The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically

begin to flash.

The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER

lamp flash indicators is listed in the instruction manual for the user's knowledge and reference. If an error symptom cannot

be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past

problems and how often these problems occur.

DIAGNOSTIC TEST INDICATORS

When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the

problem. If there is more than one error, the lamp will identify the first of the problem areas.

Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a "0".

Symptoms

· Power does not come on.

· No power is supplied to the

TV.

· AC power supply is faulty.

· Power does not come on.

· Load on power line is

shorted.

· Has entered standby state

after horizontal raster.

· Vertical deflection pulse is

stopped.

· Power line is shorted or

power supply is stopped.

· No raster is generated.

· CRT cathode current

detection reference pulse

output is small.

· Power is shut down shortly,

after this return back to

normal.

· Detect Micro latch up.

Note 1: If a + B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.

The symptom that is diagnosed first by the microcontroller is displayed on the screen.

Note 2: Refer to screen (G2) Adjustment in section 3-4 of this manual.
