Insert the sim card removal tool into the hole located at the top of the phone. Press the tool firmly into the phone to get the sim card tray to eject from the slot.
Remove the two Phillips head screws located on the top of the phone.
One is hidden under an orange sticker, removal of this sticker will void your warranty, this sticker can be removed using a set of tweezers.
Removal of the orange sticker reveals a hidden screw that needs to be removed.
We now want to insert a pry tool into the upper portion of the phone, where there is a small gap between screen and frame of the phone.
Be careful when working the pry tool on the phone as it can result in damage to the phone's screen or other components.
Once a pry tool has been inserted into the phone, work it around the entire perimeter of the phone until the screen of the phone separates from the frame.
Once a pry tool has been inserted into the phone, work it around the entire perimeter of the phone until the screen of the phone separates from the frame.
The phone should now be separate from the exterior frame portion of the phone.
Place the phone screen side down with the camera located at the top.
Remove the 7 Phillips head screws, located on the upper portion of the phone.
One of these screws is hidden under an orange sticker at the top right corner of the phone, removal of this sticker can be removed using a set of tweezers.
Remove the 3 screws located at the bottom of the back side of the phone.
Using tweezers, remove the rubber dust cover on the back panel of the phone.
Not necessary for this goal. Do this for your own fun, if you like. Insert a plastic opening tool into the bottom of the phone, then work it around the lower portion of the phone in order to remove it from the plastic cover.
Insert a plastic opening tool into one of the top corners of the phone, then work it around the exterior portion of the phone until the plastic cover can be easily removed from the phone.
After working the pry tool the top cover can be easily removed.
Some models have their NFC antenna on the back of the battery glued to the top cover. It is not possible to remove the top cover without the battery. In that case, check the touchscreen guide.
Using a spudger, remove the small ribbon cable that is connected to the battery.
Now grab a hold of the "Battery Removal" tab that is attached to the battery, located at the left side of the back portion of the phone. Lifting up on the tab should remove the battery out of the phone.
It may take some force to remove the battery as it is also adhered to the phone with two pieces of double sided tape.

Echo Dot – Specification – Disassembling procedure

SPECIFICATION
1. Dual-band, dual-antenna 802.11 a/g/b/n Wi-Fi with MIMO
2.  Alexa Voice Search
3. 7-microphone array
4. Light ring volume adjustment
5. Bluetooth 4.0 for sending and receiving audio
6. 3.5 mm audio output for external speakers
DISASSEMBLING PROCEDURE
Peel away the grippy rubber pad, fully expecting to find first screws
lower case simply clips in place, but when the first opening pick fails to pop it free, insert another.
First look inside reveals what sophisticated tech insiders will instantly recognize as a big metal thing.
This steel plate appears to be the culprit behind somewhat frustrated .
Fortunately, this metal thing has screws. Some long T6 Torx screws are threaded through the Dot from bottom to top.
It’s a speaker, albeit a small one. It connects to the Dot by way of a couple pairs of spring contacts.
It's not punchy enough for playing music, but it gives Alexa a way to talk back if your other speakers are turned off or disconnected.
With the screws removed, only a thin ribbon cable ties all these layers together.
At one end lies the motherboard and ports, while a separate board at the other end hosts the volume controls and microphone array. A single cable threads its way through the intervening layers to connect the two boards.
shuffle the layers of plastic and silicon back together temporarily; it's all coming apart soon enough
After tweezing away the ribbon cable, ready to inspect the motherboard.
Chips on one side, ports on the other. Here's what this motherboard is packing:
Texas Instrument DM3725 Digital Media Processor
Micron MT46H64M32LFBQ 256 MB (16 Meg x 32 x 4 Banks) LPDDR SDRAM
Samsung KLM4G1FEPD 4GB High Performance eMMC NAND Flash Memory
Qualcomm Atheros QCA6234 Integrated Dual-Band 2x2 802.11n + Bluetooth 4.0 SiP
Texas Instruments TPS65910A1 Integrated Power Management IC
Texas Instruments DAC
With disassembly nearly complete, tear into the control wheel. It's a dead ringer for the one we found in the original Echo, complete with its geared encoder wheel.
That's just fine by us, since it means at least some replacements parts can likely be shared between the original Echo and the Dot.
It also means servicing instructions for one will likely be echoed by the other. All in all, it's a win for fans of repair and bad puns everywhere.
We slap the control ring back together just long enough to see the encoder wheel doing its thing.
There's just something soothing about gears.
And buried in the top layer find another control board, functionally identical to the one we dug up in the original Echo.

Nokia Lumia 610 – Disassembling procedure – How to replace the touch screen

Slide the back cover off, and remove the battery
There are 8 Torx 5 screws you have to remove, 4 on each side
After removing all 8 screws, proceed to prying off the back cover
This is done very easily; by prying it from the 3 grooves depicted
This step might also be done using your nails, as the clips are not strong at all
Watch out - the buttons easily fall out; just make sure you don't loose any.
Lift the back cover up, and pull it back - most likely, the 2 sided tape sealing the camera module will be the last thing to break loose
Make sure you stick it back to the rear case assembly after this step
Disconnect the 2 ribbon cables connecting the LCD & Digitizer to the motherboard
Lift the motherboard up from the back, and pull it backwards
Apply the same motion as with the back casing
You should now have separated the motherboard from the LCD/Digitizer Assembly
To detach the LCD, gently lift it from the sides - be careful, and don't pull too hard on the ribbon cable.
It's secured in with pretty weak double-sided tape, so this step shouldn't be a problem.
Remove the ear-piece speaker from the Digitizer Assembly
It's held in by - again - pretty weak double-sided tape
2nd picture gives you a look of the front of the speaker unit - it's pretty hard to damage the membrane - though, be too careful
Something very easy to forget - removes the tiny rubber gasket for the microphone, and places it in the new front panel.

Apple Thunderbolt Display - How to remove the display – How to remove the power supply – how to remove the mother board

SPECIFICATION 

27" TFT Active-Matrix LCD
2560 by 1440 Pixel Resolution
Built-in Thunderbolt and MagSafe Cables
FaceTime HD Camera with Microphone
49 Watt 2.1 Speaker System
16:9 Widescreen Aspect Ratio

The Thunderbolt Display contains a sweet lineup of USB, HDMI, VGA, and DisplayPort ports
The luscious backside of the Thunderbolt Display contains only a small line of specified ports:
Three powered USB 2.0 ports
FireWire 800 port
Thunderbolt port
Gigabit Ethernet port.
The Thunderbolt Display also comes with a built-in Thunderbolt cable attached to a Universal MagSafe cable.

DISASSEMBLING PROCEDURE 

Much like the iMac we tore apart earlier this year (and the iMacs before it), the Thunderbolt
Display's front glass panel comes off with the help of some heavy duty suction cups.

It's time to take a look under the hood. A few connectors and a ground screw are all that prevent the freedom of the LCD

The 27-inch (diagonal) TFT activematrix LCD has a resolution of 2560 by 1440 pixels, the standard for displays of this size and price. Its 12 ms response time and 16.7 million colors, however, fall short of the 6 ms response time and 1.07 billion colors

The back of the LCD display has only a few cables, none too exciting:

DisplayPort
LED backlight
LED backlight sync
Ground loop.
The LG display reads model number LM270WQ1.

It appears to be the same display found in the iMac Intel 27"

With  LCD removed you get a full frontal view of the Thunderbolt Display's inner layout.

The fan is easily removed simply by detaching a couple of connectors and unfastening a few screws.

Apple has, as usual, chosen to go with a large, brushless fan to keep the colossal Thunderbolt Display nice and cool.

 In pursuit of self-preservation, begin by disconnecting the power supply connector from its socket on the logic board to prevent any electrifying experiences.

A few more T10 Torx screws bite the dust at the hand of our bit driver kit, and the logic board is detached.

Remove a plethora, of connectors from the logic board, leaving only the brains behind the Thunderbolt port between us and the display's control center.

A few T6 Torx screws are knocked out to remove the connector cover, and the Thunderbolt cable is disconnected.

Interestingly enough, the Thunderbolt cable that routes into the display also plugs into a standard Thunderbolt socket on the logic board. Apple could have just soldered the cable wires to the board, but instead chose to implement a cover that prevents the cable from being detached from the logic board's Thunderbolt socket

St. Damien's beard! The front of the logic board includes these stellar packages:

Pericom PI7C9X440SL PCIe-to-USB 2.0 host controller L129NB11 EFL, which looks to be the Thunderbolt port controller 
Analog Devices ADAV4601 audio processor
NXP LPC2144 USB 2.0 microcontroller
Delta LFE9249 10/100/1000 Base-T LAN filter
SMSC USB2517-JZX USB 2.0 hub controller
LPC 1114F

Sweet grandmother's spatula! The back of the board also contains doodles of chips:

Maxim MAX9736B Mono/Stereo
High-Power Class D Amplifier
Texas Instruments LC573A Dtype Latch
Silego SLG8SP568VCK505 Clock Generator
LSI L-FW643E-2 Open Host Controller Interface
Broadcom BCM57761 Gigabit ethernet controller
Texas Instruments NH245 Dual Supply Translator
Supertex HV9982 3-channel switch-mode LED driver IC

With the logic board removed, we move on to the power supply board.

A few screws and connectors are all that are stopping us from removing the board.
Make quick work of them and the Flextronics power supply board comes free.

Thunderbolt Display's power supply board

About 250 watts of maximum continuous power

You will see some fairly large speaker enclosures (well, for a monitor) near the side edges of the Thunderbolt Display and eagerly remove the screws holding them in place.

The Thunderbolt Display comes with a 49 watt 2.1-speaker sound system, including a miniature subwoofer.

A couple screws and a single connector keep the HD FaceTime camera secured to the case.

LUBRICATING TREADMILL RUNNING BLT AND DECK
It is necessary to lubricate your treadmill running deck every six months or 150 miles (240 kilometers) to maintain optimal performance. Once the treadmill reaches 150 miles (240 kilometers), the console will dispHay the message “LUBE” or “LUBE BELT”. The treadmill will not operate while the message is showing. Hold ‘STOP’ for 5 seconds to suspend message for 5 miles.
Your treadmill came with a bottle of lubricant which can be used for two applications.
# Turn off the treadmill with the on/off switch, then unplug the power cord at the wall outlet.
# Loosen both the rear roller bolts. (for best results, place two removable marks on both sides of the frame and note roller position). Once the belt is loosened, take the bottle of lubricant and apply it to the entire top surface of the running deck. Tighten both rear roller bolts (matching up the marks for proper position) to original position. After you have applied lubricant, plug in the power cord, insert the safety key, start the treadmill and walk on the belt for two minutes to spread the lubricant.
# Lubricate the air shocks with Teflon based spray.
RESETTING LUBE MESSAGE
Once lubrication is complete, reset the console by pressing and holding ‘STOP’ and ‘SPEED +’ buttons for 5 seconds.
TENSIONING & CENTERING THE RUNNING BELT
If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common adjustment. To eliminate this slipping, turn the treadmill off and tension both the rear roller bolts using the supplied Allen wrench, turning them 1/4 turn to the right as shown. Turn the treadmill on and check for slipping. Repeat if necessary, but never turn the roller bolts more than 1/4 turn at a time. Belt is properly tensioned when the slipping sensation is gone.
The running belt has been properly adjusted at the factory before it was shipped. At times the belt can move off-center during shipment. Before operating the treadmill, make sure the belt is centered and remains centered to maintain smooth operation.
If the running belt is too far to the right side: With the treadmill running at 1 mph, turn the left adjustment bolt counter-clockwise 1/4 turn at a time (using the supplied Allen wrench). Check the belt alignment. Allow belt to run a full cycle to gauge if more adjustment is needed. Repeat if necessary, until the belt remains centered during use.
If the running belt is too far to the left side: With the treadmill running at 1 mph, turn the right adjustment bolt counter-clockwise 1/4 turn at a time (using the supplied Allen wrench). Check the belt alignment. Allow belt to run a full cycle to gauge if more adjustment is needed. Repeat if necessary, until the belt remains centered during use.

Precor Fitness Equipment – Precor Treadmill – Precor Elliptical - Error Code Troubleshooting

ERROR 01, 02, 03, 04 - Memory, Ram & EEPROM Test Errors

Applies to All cardio equipment
Issue Symptoms
Errors 00 through 04 check upper PCA memory locations, RAM memory locations, and the EEPROM checksum during the power up test sequence. If a fault is found during the power up test sequence, the appropriate error code will be displayed. While rare, these messages may display intermittently due to external causes. If the unit's AC input significantly dips during the power up test sequence the test could fail resulting in triggering one of these errors. In addition, treadmills operating on non-dedicated branch AC circuits may see these errors on an intermittent basis.
Troubleshooting
1 Reproduce the error and evaluate
a. Turn off unit.
b. Turn on unit. Repeat.
c. If the error message is consistently displayed when the unit is powered up, replace the upper PCA

ERROR  (05) - Key In The Operated Position At Power Up

Applies to All consoles
NOTE: Error 05 has not been displayed on Precor equipment since 2003. It was replaced by the simpler “Stuck Key” message, and is not recorded in the error log.
Issue Symptoms
The power up test sequence has detected a key in the operated condition. A permanently stuck key inhibits the correct operation of the unit. Likely causes are liquids present on a touch sensitive display, or a key in the display housing is stuck in the operated condition. Less likely but possible is a failure on the upper PCA.
Troubleshooting steps
1. Check for visible liquid
2. Wipe off any visible liquid from the surface of the touch sensitive display.
3. Restart the unit. If error 5 is no longer present, the liquid was the cause.
4. Test the keypad
5. Turn off the unit.
6. Remove the keypad connector cable from the upper PCA.
7. Restart the unit, if error 5 is no longer present, the keypad is the cause. Note that the keypad is typically part of the display housing.
8. Replace the display housing to correct the problem.
9. Test the upper PCA
10. Turn off the unit.
11. Remove the keypad connector cable from the upper PCA.
12. Restart the power up sequence, if error 5 is still present, the upper PCA is the cause.

ERROR 09 - Lower PCA Memory Test Errors

Applies to All cardio equipment
Description
During the power up test sequence the lower PCA memory locations are checked. Error 09 indicates that a fault was found. This error message almost always indicates a lower PCA problem when it is consistently displayed. Failures causing this error message to be displayed are rare. These messages may display intermittently due to external causes. If the unit's AC input significantly dips during the power up test sequence the test could fail resulting in triggering one of these errors. In addition, treadmills operating on non-dedicated AC circuits may see these errors on an intermittent basis.
Troubleshooting steps
1. Reproduce the error and evaluate
a. Turn off unit.
b. Turn on unit. Repeat.
c. If the error message is consistently displayed when the unit is powered up, replace the lower PCA.

Error 10 - Line Frequency Out Of Acceptable Range

Applies to Treadmills built since 2006
Issue Symptoms
The AC line frequency must be either 50Hz or 60Hz for Experience treadmills built 2006 2013, and between 45Hz and 65Hz for TRM800 v2 (2014 onward). Error 10 is triggered if the line frequency moves beyond these acceptable ranges, or if electrical noise is generated causing a perceived change in frequency. Error 10 can also be caused by electrical wiring and supply issues, such as shared neutrals or AC hot and AC neutral wires being reversed. If facility power is lost, and a backup generator turns on the frequency can be off for a short time, causing Error 10.
Troubleshooting
Verify electrical supply
1. Treadmills must be installed on an AC 20 amp dedicated branch circuit. Both the hot and neutral leads must be dedicated to the treadmill. If another piece of equipment is sharing a circuit with the treadmill it can create enough electrical noise to make AC line frequency identification impossible. The treadmill’s AC
circuit must be reconfigured as a completely dedicated 20 amp circuit.
2. Most line frequency detection systems monitor the AC line frequency on the hot AC line. In the case of a reversed 120 V.A.C circuit, the monitoring is taking place on the neutral (ground) side of the AC line. Many of the monitoring systems are incapable of detecting line frequency on the neutral wire. It must first be determined if the reversal is in the AC wiring feeding the treadmill or in the treadmill internal wiring. The hot and neutral wires can be verified by measuring each in reference to AC (green wire) ground.
3. Even though unlikely, the AC line frequency could actually be out of acceptable limits. This is more likely to occur in countries where AC power systems may not be well developed and controlled. There may be little that can be done about this condition. If a generator is used during a power outage, during the time the generator is coming up to speed the line frequency may be detected as incorrect.
4. Sometimes AC being fed into the distribution system is too electrically noisy to allow correct line frequency identification. This can be caused by other equipment within the AC distribution system creating the electrical noise. Identifying the source of the electrical noise can be difficult. There may be little that can be done about this condition.

ERROR 11 - Low Voltage Watchdog (Upper PCA)

Applies to Treadmills and powered Ellipticals
Issue Symptoms
This watchdog program monitors the voltage of the upper PCA and displays error 11 if it drops below the acceptable value. This can be present if the communications cable between the lower PCA and the upper PCA is faulty, or if a failure in the upper PCA causes an overload in the low voltage power supply, causing it to drop below the limit.
It is also possible to see this message displayed intermittently due to external causes. If the unit's AC input significantly dips during the power up test sequence the test could fail resulting in this message being displayed.
Treadmills operating on non-dedicated AC circuits may see this message displayed on an intermittent basis.
Troubleshooting
1. Test the interconnect cable
a. Clear the error log and turn off unit.
b. Substitute a known good interconnect cable in place of the existing cable directly between the upper PCA and lower PCA.
c. Turn on unit and check the error log.
2. Check the upper PCA
a. Cycle power of the unit and check the error log.
b. If the error is consistently displayed when the unit is powered up, replace the console

ERROR 12 - Low Voltage Watchdog (Lower PCA)

Applies to Treadmills and powered Ellipticals
Issue Symptoms
This watchdog program monitors the voltage of the lower PCA and displays error 12 if it drops below the acceptable value. This can be present if the communications cable between the lower PCA and the upper PCA is faulty, or if a failure in the upper PCA causes an overload in the low voltage power supply, causing it to drop below
the limit. It is also possible to see this message displayed intermittently due to external causes. If the unit's AC input significantly dips during the power up test sequence the test could fail resulting in this message being displayed.
Treadmills operating on non-dedicated branch AC circuits may see this message displayed on an intermittent basis.
Troubleshooting
1 Test the interconnect cable
2 Clear the error log and turn off unit.
3 Substitute a known good interconnect cable in place of the existing cable directly between the upper PCA and lower PCA.
4 Turn on unit and check the error log.
5 Check the upper PCA
6 Cycle power of the unit and check the error log.
7 If the error is consistently displayed when the unit is powered up, replace the console.

ERROR 14 - Fan Fail (Lower PCA)

Applies to
Treadmills
Issue Symptoms
The rotation of the cooling fan used to cool the lower PCA is monitored. If the fan is not rotating or rotating too slowly an error 14 will be logged. Typical symptoms include the heatsink by the fan can getting clogged with dust and/or dirt, the fan connector/cable becoming disconnected or damaged, the drive motor cable routed such that it is preventing the fan from turning, or the fan itself is failed.
Troubleshooting
1 Visually inspect the fan
2 Clear the error log.
3 Turn off unit.
4 Remove any debris from the fan.
5 Reset the motor cable as required.
6 Turn on unit, test when running the belt.
7 Inspect the fan connector
8 Turn off unit.
9 Inspect and reconnect the fan connector.
10 Visually inspect the drive motor cable for clearance away from the fan
11 Visually inspect the fan for movement during operation
12 If the fan does not move, replace the lower PCA.

ERROR LS - Speed Sensor Signal Missing
Applies to
9.23, 9.27
Issue Symptoms
This error is displayed in the display’s TIME window when the drive motor speed signal is not received from the speed sensor for eight consecutive seconds. When the LS error occurs, all drive motor and lift motor motion is halted and the display is blanked except for the error display. The treadmill utilizes a reed switch and two magnets in the drive roller pulley as a speed sensing system. The most likely causes for this are the speed sensor wiring having an intermittent or open connection, an intermittent or defective reed switch, or bad drive motor brushes. Least likely but possible is a bad upper PCA.
Troubleshooting 
1 Check the reed switch wiring and connection to the lower PCA.
2 Check the reed switch using an ohmmeter while rotating the drive pulley. The reed switch will close when
a magnet passes in front of it.
3 Replace both drive motor brushes.
4 Substitute a known good upper PCA to determine if the upper PCA is bad.

ERROR E2 - Lift Error
Applies to
9.23, 9.27
Issue Symptoms
This error is displayed in the display’s TIME window indicating an incline problem. This error will occur if the incline is unable to move or if the incline position potentiometer is not functioning. When the E2 error occurs, all drive motor and lift motor motion is halted and the display is blanked except for the error display.

Troubleshooting 

1 If the lift motor has drifted too low, disconnect the motor from the lift assembly and adjust the jack screw until the motor is in range. Perform the appropriate lift motor calibration procedure. If the motor continues to drift low, replace the motor.
2 Inspect the lift motor connector, verifying the pins are secure in the connector. Attach the connector to the lower PCA and ensure that it is locked into the header.
3 Enter Diagnostics, Machine Test, Incline or Crossramp test. Run the lift all the way extended and back to minimum. The A/D number should climb and decrease smoothly during the test. If not, replace the lift motor.
4 While in the Incline or Crossramp test scroll to see Glitches, and run the lift to both extremes. Glitches are anomalies recorded by the lower board during lift movement, indicating a possible or existing problem with the internal potentiometer or the gearing that turns it. Very few if any glitches should be recorded. If greater than 50 glitches are recorded during a full movement to either extreme, replacement of the lift motor is necessary.
