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.
1.
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".
Diagnostic

Description
· Power does not
turn on
· +B overcurrent

overvoltage
(OVP)
· Vertical deflection

PICTURE)
· Micro reset
Detected
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.
