How to set up a home network server to share photos, music and movies in all your rooms

How to perform a (soft) restart (reset) or Power cycle on Sony's Android TV, Power cycle, How to hear the television sound through the speakers of a stereo receiver or home theater system

By setting up your computer or network storage device as a home network server, you can stream photos, music, and movies over your home network to a client, such as a TV, tablet, Smartphone, PlayStation or Blu-ray Player.
Both the server and the client need to support the home network function. To verify whether your Sony devices support the home network function, check the User Manual.
For Windows operating systems (depending on your operating system and preference) follow one of the links below to set up your home network server.

If using the Windows Media Player 12 software and the Windows7 or 8 or 8.1 operating system,
Follow this procedure.

For Macintosh and Linux operating systems, “Serviio” can be used. (Search for Serviio by Google)

Serviio is a free media server. It allows you to stream your media files (music, video or images) to renderer devices (e.g. a TV set, Bluray player, games console or mobile phone) on your connected home network.

There is also a paid “Pro edition” which further enhances the possibilities of sharing content in your connected household.

Serviio works with “many devices” from your connected home (TV, Playstation 3, XBox 360, smart phones, tablets, etc.). It supports profiles for particular devices so that it can be tuned to maximise the device's potential and/or minimize lack of media format playback support (via transcoding).

Serviio is based on Java technology and therefore runs on most platforms; including Windows, Mac and Linux (incl. embedded systems, e.g. NAS).

NOTES The third-party software recommended above are provided for your convenience and should be used at your own risk. Sony does not support nor guarantee the reliability of unsupplied 3rd party software.

After you set up the home network server, follow the set up instructions for your home network device to connect to the server.

How to check and replace the magnetron – Electrolux Microwave oven

Magnetron check, High voltage rectifier check, High voltage capacitor check, High voltage rectifier check and more..

REMEMBER TO CHECK 3D
1) Disconnect the supply.
2) Door opened, and wedged open.
3) Discharge high voltage capacitor.

WARNING AGAINST THE CHARGE OF THE HIGH VOLTAGE CAPACITOR

The high-voltage capacitor remains charged about 60 seconds after the oven has been switched off.

Wait for 60 seconds and then short-circuit the connection of the high-voltage capacitor (that is, of the connecting lead of the high-voltage rectifier) against the chassis with the use of an insulated screwdriver.

If the oven becomes inoperative Because of a blown fuse F2 (F8A) in the monitored latch switch SW1 – monitor switch SW3 circuit, check the monitored latch switch SW1 and monitor switch SW3 before replacing the fuse F2 (F8A).

MAGNETRON TEST

CARRY OUT 3D CHECK

Isolate the magnetron from high voltage circuit by removing all leads connected to the filament terminal.

To test for an open circuit filament use an ohmmeter to make a continuity test between the magnetron filament terminals, the meter should show a reading of less than 1 ohm.

To test for a short circuit filament to anode condition, connect ohmmeter between one of the filament terminals and the case of the magnetron (ground). This test should be indicated an infinite resistance. If a low or zero resistance reading is obtained then the magnetron should be replaced.

MICROWAVE OUTPUT POWER (IEC-60705-1988)
The following test procedure should be carried out with the microwave oven in a fully assembled condition (outer case fitted). Microwave output power from the magnetron can be measured by way of IEC 60705, i.e. it is measured by how much power the water load can absorb. To measure the microwave output power in the microwave oven, the relation of calorie and watt is used. When P(W) heating works for t(second), approximately P x t/4.187 calorie is generated. On the other hand, if the temperature of the water with V(ml) rises ΔT (°C) during this microwave heating period, the calorie of the water is V x ΔT.

The formula is as follows;

P x t / 4.187 = V x Δ T+0.55 x mc (T2-T0)

Our condition for water load is as follows:

Room temperature.....................around 20°C

Water load..........................................1000 g

Heating time........................................47 sec.

T2......................................Final Temperature

P (W) = 4.187 x V x ΔT / t

Power supply Voltage........Rated voltage

Initial temperature(T1).............10 ± 1°C

Mass of container (mc)....................330 g

P = 90 x ΔT + 0.55 x mc (T2-T0)/47

Measuring condition
1. Container
The water container must be a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190 mm.
2. Temperature of the oven and vessel.
The oven and the empty vessel are at ambient temperature prior to the start of the test.
3. Temperature of the water The initial temperature of the water is (10 ± 2)°C.
4. Select the initial and final water temperature so that the maximum difference between the final water temperature and the ambient temperature is 5K.
5. Select stirring devices and measuring instruments in order to minimize addition or
removal of heat.
6. The graduation of the thermometer must be scaled by 0.1°C at minimum and an accurate thermometer.
7. The water load must be (1000 ± 5) g.
8. “t” is measured while the microwave generator is operating at full power. Magnetron filament heat-up time is not included.
NOTE: The operation time of the microwave ovens is “t + 3” sec. (3 sec. is magnetron filament heat-up time.)

Measuring method

1. Measure the initial temperature of the water before the water is added to the vessel. (Example: The initial temperature T1 = 11°C)

2. Add the 1 litre water to the vessel.

3. Place the load on the centre of the shelf.

4. Operate the microwave oven at HIGH for the temperature of the water rises by a value ΔT of (10 ± 2) K.

5. Stir the water to equalize temperature throughout the vessel.

6. Measure the final water temperature. (Example: The final temperature T2 = 21°C)

7. Calculate the microwave power output P in watts from above formula.

Room temperature ................T0 = 21°C Initial temperature............. T1 = 11°C
Temperature after (47+ 3) = 50 sec................................................... T2 = 21°C
Temperature difference Cold-Warm.................................................ΔT1 = 10°C
Measured output power
The equation is “P = 90 x ΔT” .................................. P = 90 x 10°C = 900Watts

The measured output power should be at least ± 15 % of the rated output power.

CAUTION: 1°C CORRESPONDS TO 90 WATTS. REPEAT MEASUREMENT IF THE POWER IS INSUFFICIENT

HIGH VOLTAGE TRANSFORMER TEST

High voltages and large currents are present at the secondary winding and filament winding of the high voltage transformer. It is very dangerous to work near this part when the oven is on. NEVER make any voltage measurements of the high-voltage circuits, including the magnetron filament.

Disconnect the leads to the primary winding of the power transformer.

Disconnect the filament and secondary winding connections from the rest of the HV circuitry. Using an ohmmeter, set on a low range, it is possible to check the continuity of all three windings. The following readings should be obtained:-

a. Primary winding ............................approximately 2 Ω

b. Secondary winding ....................approximately 127 Ω

c. Filament winding ..................................less than 1 Ω

If the reading obtained are not as stated above, then the power transformer is probably faulty and should be replaced.

HIGH VOLTAGE RECTIFIER TEST

Isolate the high voltage rectifier assembly from the HV circuit. The high voltage rectifier can be tested using an ohmmeter set to its highest range. Connect the

ohmmeter across the terminal B+C of the high voltage rectifier and note the reading obtained. Reverse the meter leads and note this second reading.

The normal resistance is infinite in one direction and more than 100 kΩ in the other direction

Isolate the high voltage rectifier assembly from the HV circuit. The asymmetric rectifier can be tested using an ohmmeter set to its highest range across the terminals A+B of the asymmetric rectifier and note the reading obtained.

Reverse the meter leads and note this second reading. If an open circuit is indicated in both direction then the asymmetric rectifier is good. If an asymmetric rectifier is shorted in either direction, then the asymmetric rectifier is probably faulty and must be replaced with high voltage asymmetric rectifier.

When the asymmetric rectifier is defective, check whether magnetron, high voltage rectifier, high voltage wire or filament winding of the high voltage transformer is shorted.

FOR MEASUREMENT OF THE RESISTANCE OF THE RECTIFIER, THE BATTERIES OF THE MEASURING INSTRUMENT MUST HAVE A VOLTAGE OF AT LEAST 6 VOLTS, BECAUSE OTHERWISE AN INFINITE RESISTANCE MIGHT BE SHOWN IN BOTH DIRECTIONS

HIGH VOLTAGE CAPACITOR TEST

A. Isolate the high voltage capacitor from the circuit.
B. Continuity check must be carried out with measuring instrument which is set to the highest resistance range.
C. A normal capacitor shows continuity for a short time (kick) and then a resistance of about 10 MΩ after it has been charged.
D. A short-circuited capacitor shows continuity all the time.
E. An open capacitor constantly shows a resistance about 10 MΩ because of its internal 10 MΩ resistance.
F. When the internal wire is opened in the high voltage capacitor, the capacitor shows an infinite resistance.
G. The resistance across all the terminals and the chassis must be infinite when the capacitor is normal.
If incorrect readings are obtained, the high voltage capacitor must be replaced.

HIGH VOLTAGE TRANSFORMER REMOVAL

1. CARRY OUT 3D CHECKS

2. Disconnect the main wire harness from the high voltage transformer.

3. Disconnect the filament leads and high voltage wire of high voltage transformer from high voltage capacitor and the magnetron.

Remove the two (2) screws and one (1) washer holding the transformer to the base plate.

5. Remove the transformer.

6. Now the high voltage transformer is free.

The line voltage is supplied to the primary winding of the high voltage transformer. The voltage is converted to about 3.3 volts A.C. output on the filament winding and high voltage of approximately 2000 volts A.C. on the secondary winding.

2. The filament winding voltage (3.3 volts) heats the magnetron filament and the high voltage (2000 volts) is sent to the voltage doubling circuit, where it is doubled to negative voltage of approximately 4000 volts D.C..

3. The 2450 MHz microwave energy produced in the magnetron generates a wavelength of 12.24 cm. This energy is channeled through the waveguide (transport channel) into the oven cavity, where the food is placed to be cooked.

4. When the cooking time is up, a single tone is heard and the relays RY1 + RY3 + RY6 go back to their home position. The circuits to the oven lamp, high voltage transformer, fan motor and turntable motor are cut off.

MAGNETRON REMOVAL

Disconnect the H.V. wire B (part of H.V. transformer) and filament lead of the transformer from the magnetron.
3. Carefully remove three (3) screws holding the magnetron to the waveguide, when removing the screws hold the magnetron to prevent it from falling.
4. Remove the one (1) screw holding the magnetron to the chassis support.

5. Remove the magnetron from the waveguide with care so the magnetron antenna is not hit by any metal object around the antenna.
6. Now, the magnetron is free.

WHEN REPLACING THE MAGNETRON, BE SURE THE R.F. GASKET IS IN PLACE AND THE MAGNETRON MOUNTING SCREWS ARE TIGHTENED SECURELY

MONITORED LATCH SWITCH, STOP SWITCH AND MONITOR SWITCH ADJUSTMENT

If the monitored latch switch, stop switch and monitor switch do not operate properly due to a mis-adjustment, the following adjustment should be made.
> Loosen the two (2) screws holding the latch hook to the oven cavity front flange.
> With the door closed, adjust the latch hook by moving it back and forward or up and down. In and out play of the door allowed by the latch hook should be less than 0.5 mm. The horizontal position of the latch hook should be placed where the monitor switch has activated with the door closed. The vertical position of the latch hook should be placed where the monitored latch switch and stop switch have activated with the door closed.
> Secure the screws with washers firmly.
> Make sure of the all switches operation. If the latch head has not pushed the plungers of the monitor switch with door closed, adjust the latch hook position. At that time, the latch head should have pushed the plungers of the monitored latch switch and stop switch. If the latch head has not pushed the plungers of the monitored latch switch and stop switch with door closed, loose two (2) screws holding latch hook to oven cavity front flange and adjust the latch hook position.

After adjustment, make sure of following:

1. In and out play of door remains less than 0.5 mm when latched position. First check the latch hook position, pushing and pulling upper portion of the door toward the oven face.  Then check the lower latch hook position, pushing and pulling lower portion of the door toward the oven face. Both results (play of the door) should be less

than 0.5mm.

2. The contacts (COM-NO) of the stop switch and the monitored latch switch open within 1.8mm gap between right side of cavity face plate and door when door is opened.

3. When the door is closed, the contacts (COM-NO) of the stop switch close.

4. When the door is closed the contacts (COM-NC) of the monitor switch and monitored latch switch open.  And the contacts (COM-NO) of their switches close.

5. Re-install outer case and check for microwave leakage around the door with an approved microwave survey meter.

2. Deviation of door alignment from horizontal line of cavity face plate is to be less than 1.0mm.

3. Door is positioned with its face pressed toward cavity face plate.

4. Check for microwave leakage around door with an approved microwave survey meter

Note: The door on a microwave oven is designed to act as an electronic seal preventing the leakage of microwave energy from oven cavity during cook cycle. This function does not require that door be air-tight, moisture (condensation)-tight or light-tight. Therefore, occasional appearance of moisture, light or sensing of gentle warm air movement around oven door is not abnormal and do not of themselves, indicate a leakage of microwave energy from oven cavity.

After adjustment of door latch switches, monitor switch and door are completed individually or collectively, the following leakage test must be performed with a survey instrument and it must be confirmed that the result meets the requirements of the performance standard for microwave oven.

the appropriate key (e.g., AUX, DVD, CBL, or STB) for the device you are checking. Write down the codes in the appropriate boxes..

PROGRAMMING CHANNEL CONTROL LOCK

By default, the remote control’s channel-control capabilities are locked to the cable converter. The affected keys are 1 through 0, CH+, CH-, and LAST. This guarantees that you do not inadvertently change a channel on your TV or VCR. However, you can de-activate this feature to allow full access to these keys in the TV and VCR modes.

Unlocking Channel Control

1. On the remote control, press CBL (or STB) once; it blinks once.  Press and hold SET UP until the CBL (or STB) key blinks twice.

2. Enter 9 7 3. The CBL (or STB) key blinks twice.

3. Press CH- once. The CBL (or STB) key blinks four times.

Now the remote control provides TV and VCR channel-control capabilities while in the TV or VCR mode.

Locking Channel Control to CBL

1. On the remote control, press CBL (or STB) once; it blinks once.  Press and hold SET UP until the CBL (or STB) key blinks twice.

2. Enter 9 7 3.The CBL (or STB) key blinks twice.

3. Press CH+ once. The CBL key blinks once.

4. Press CBL once. The CBL key blinks twice.

Now, regardless of what mode you select, the channel keys only change channels on your cable converter.

CHANGING VOLUME LOCK
Volume Lock allows you to control the volume through the device identified as having your primary speaker(s), regardless of which mode you are using. On the C4000RemoteControl,Global Volume Lock is set to TV, so you can control TV volume while in the AUX, DVD, TV or CBL mode. You can perform Individual Volume Unlock on a selected device to set its volume control for independent operation.

Unlocking Volume Control for a Single Device (Individual Volume Unlock)
1. Assuming Global Volume Lock is active, select a mode on the remote control that you want to unlock (e.g., CBL) and press it once. Next, press and hold SET UP until the device key blinks twice.
2. Enter 9 9 3. The last-selected device key blinks twice.
3. Press VOL- once. The last-selected device key blinks four times.

Now, after you select a device that has volume unlocked (e.g., CBL), pressing VOL+, VOL-,or MUTE, controls only that device’s volume.

Unlocking All Volume Control (Global Volume Unlock)

NOTE: Performing these instructions sets independent volume control for all programmed devices.

1. On the remote control, press and hold SET UP until the last selected device key blinks twice.

2. Enter 9 9 3. The last-selected device key blinks twice.

3. Press VOL+ once. The last-selected device key blinks four times.

Locking Volume Control To One Mode (Global Volume Lock)

1. On the remote control, press and hold SET UP until the last selected device key blinks twice.

2. Enter 9 9 3. The last-selected device key blinks twice.

3. Select a mode (e.g., TV or AUX) which you want to use to control the volume. The selected device key blinks twice.

Now, when you press VOL+, VOL-,or MUTE, the volume of the selected device (e.g., TV) is controlled regardless of mode.

USING THE SYSTEM ON/OFF KEY

1. Press SYSTEM ON/OFF once. Your devices turn on or off in the pre-programmed sequence.

NOTE: Only devices you have programmed the remote to control turn on or off sequentially. For example, if you have programmed control of your TV, but not your DVD player, SYSTEM ON/OFF does not turn your DVD player on or off.

USING KEYMOVER

The C4000 Control includes a Key-mover feature that allows you to map (or copy)keys from one mode (i.e., source mode) to another mode (i.e.,destination mode).

Programming Key  mover

For example, if your DVD player does not have volume control, you can map those keys (i.e., VOL+, VOL-, and MUTE) from the TV mode to DVD mode as follows:

1. On the remote control, press CBL (or STB) once; it blinks once.  Then press and hold SET UP until the CBL (or STB) key blinks twice.

2. Enter 9 9 4. The CBL (or STB) key blinks twice.

3. For the source mode, press a desired device key once (i.e., AUX,TV, DVD, CBL or STB). For this example, press TV once.

4. For the source key, press a key to be moved once. For this example press VOL- once.

5. For the destination mode, press a desired device key once (i.e., AUX, TV, DVD, or CBL or STB). For this example, press DVD once.

6. For the destination key, press a key to be moved once. For this example press VOL+ once.

7. Repeat steps 1 to 6 to move additional keys. For this example, repeat steps 1 to 6 two more times to map the remaining volume control keys, substituting VOL- and MUTE as source and destination keys in steps 4 and 6.

Upon completion of the above procedure, you can now use your C4000 Remote Controls to control the TV’s volume and mute in the DVD mode, as well as in the TV mode.
