It makes sense to avoid exposure to electrical shock.  While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

SELF-DIAGNOSTIC FUNCTION

The units in this manual contain a self-diagnostic function. If an error occurs, the POWER/STANDBY will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the POWER/STANDBY flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom is difficult to reproduce use the Remote Commander to display the record that is stored at the internal NVM to specify the cause of the failure.

Diagnostic Test Indicators

When an error occurs, the POWER/STANDBY will fl ash a set number of times to indicate the possible cause of the problem. If there is more than one error, the POWER-STANDBY will identify the first of the problem areas. If the errors occur simultaneously, the one that corresponds to the fewest flashes is identified first.

Results for all of the following diagnostic items are displayed on screen. (No error has occurred if the screen displays a “0”.)

DISPLAY OF POWER-STANDBY OR LAMP LED FLASH COUNT

One flash is not used for self-diagnosis.

RELEASING THE POWER-STANDBY LED FLASH

Unplug the power cord from the outlet to temporarily stop the POWER-STANDBY lamp from flashing.

Self-Diagnostic Screen Display

For failures that are difficult to reproduce, or accompany occasional power off and/or picture mute, the Self-Diagnostic screen display is useful to specify the cause.

VIEWING THE SELF-DIAGNOSTIC SCREEN

The TV MICRO service menu contains a Log category that stores the errors. To view the fi rst error detected, display the SHUTDOWN-LOG1 Adjustment Item of the STATUS category. If other errors are detected, they are stored in the SHUTDOWN-LOG2 Adjustment Item of the STATUS category.
