Question about Sony FD Trinitron WEGA KV-36FS120 36" TV
My Sony Trinitron Wega kv-36fs120 wont turn on, standby/timer LED flashes 9 times. Occasionally the tv comes on but wont cycle on/off again. I've tried leaving it unplugged for over 24 hours, no difference. Any ideas?
1. Place set on flat solid surface (garage floor or driveway).
2. Bang into it with SUV 3 or 4 times.
3. If set fails to respond, crush against garage wall or drive over it

My Sony Trinitron Wega KV-32FS120 will turn on occasionally and works great when it comes on. If it gets turned off it takes 2 hrs of messing with it before it will come on. The Led light flashes 9 times. I have also tried leaving it unplugged nothing works. Please help or I will never buy a sony again. By the way the tv is only 2 years old.

My t.v. had the same wording on the screen. I fixed my by when power came on I hit number 5 you will see feature NTSC then you will see IDO then you hit 6 to make all 0s. Then you hit 1 you will see ID 1 hit 6 again and hit all 0's and so on keep doing that until ID 7. You can cut it on and off with the power button and the wording will be gone. If you loose power or unplug it you will have to do it all over again I have not figured out how to save it yet.

Replace standby D647 with a good 1N1007 1kv protected diode and most will then work OK, if not the other parts in the standby voltage has been damaged or just cold solder connections at fault.

Try checking the soldered joints on the main circut board that attach the larger metal components...I re-soldered aprox 40 connections and now the tv works great!

I had the same problem - soulution- try using a different socket. thats what worked for me, after they are plugged in so long in one outlet they over use it, making it not work at all.

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.

Thank you for your question.
Fortunately this is a common symptom and there is a fix for it.
There are two power supply IC's and a capacitor that need to be change. In particular IC6501, IC8002, part number, Mcz3001db, and C6556, 33uF @ 160V.
