Hola, tuqui.net,
Comienza (si aún no lo hiciste) resoldando chopper y periféricos, también flyback.
Controla estado de electrolíticos en fuente.
Saludos.

1. DIAGNOSTIC TEST INDICATORS
When an error 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.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a "0".
Diagnostic Item No. of times Self-diagnostic display/ Probable Cause Detected Symptoms
Description STANDBY/TIMES Diagnostic result Location
lamp flashes
• Power does not turn on Does not light • Power cord is not plugged in. • Power does not come on.
• Fuse is burned out (F5050). (E Board) • No power is supplied to the TV.
• AC power supply is faulty.
• +B overcurrent (OCP) 2 times 2:0 or 2:1 • H.OUT (Q502) is shorted. (A Board) • Power does not come on.
• IC1701, Q946, Q947 is shorted. (C Board) • Load on power line is shorted.
• Vertical deflection stopped 4 times 4:0 or 4:1 • +13V is not supplied. (A Board) • Has entered standby state after
• IC 541 is faulty (A Board) horizontal raster.
• Vertical deflection pulse is stopped.
• Power line is shorted or power
supply is stopped.
• White balance failure 5 times 5:0 or 5:1 • Video OUT (Q306, Q307, Q308) is • No raster is generated.
(not balanced) faulty. (A Board) • CRT cathode current detection
• IC301 is faulty. (A Board)
• G2 is improperly adjusted. (Note 2)
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.
