Question about Sony FD Trinitron WEGA KV-36FS120 36" TV

Sony Trinitron won't turn on most of the time

Our Sony Trinitron Wega will only turn on occasionally. Once we have it on and it is turned off, it has to sit for a long time before we can try again. The standby/timer light flashes nine times and then pauses. I have checked the timer when the TV was on. It is not set. After reading some things online, I assume it needs a repair. Any recommendations?

Our TV is a 36 inch but I am not sure which of the two models it is

Sony Trinitron Wega kv-36fs120 wont turn on, standby/timer LED flashes 9 times.

The relay is in the power supply area. I am sure that the fault is not the relay.

It is very common that there are various components starting to go off spec from age. Most of the failures are in the scan amplifiers and power supply areas.

It is also possible that the CRT emission is too low from age. What happens is that it is on the minimum edge and this explains why the set may turn on some of the time.

When the main uPC in the set sees any potential fault conditions it will go in to a protection mode to prevent damage and to be safe. Your set is probably borderline to operate.

Considering the age of your set, I would be shopping for a new TV set.
