Power Problem AGAIN!! KV-32FS120

KV-32FS120. Set started with occasional problem coming on. What I mean is you would have to hit the power supply button or remote power more than once to turn on. Problem got worse over several weeks until finally set doesn't power up at all other than no matter how many times you hit power! (8 blink code.) Any thoughts for repair or just right off set.

Thanks for your help!!!!!!

    Just to add to my previous question. The TV worked great other than the power problem. Once it was on video and sound were great and it never turned itself off. Just had problems turning it on.

    Not 8 blinks but 9. Sorry!

Wish I could reach the set from here; I'm pretty sure the problem is caused by a 50 cent (maximum!) part called a capacitor in the range of 4.7 - 100 uFd that is responsible for feed back that keeps the power supply ticking. If you decide to have it repaired and the problem is as above, tell the tech to use a low ESR part and add a .1-.5 uFd ceramic capacitor in parallel to the one he/she replaces. That cap will handle the fast rise times that causes the electrolytic cap to break down chemically and fail.

Won't turn on


Capacitors in the power supply section. Same area where your power chord is soldered to the board. Be sure to discharge the set before attempting to work on it. High voltage kills. Good luck and stay safe!

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.

Sony KV-32FS120 dead


It is impossible to guess at the parts without actaully troubleshooting the set with the proper setup.

From past experience, the areas that the fault for this normaly is, are the horizontal output ampliifer, main power supply, and sometimes there may be a problem with the vertical deflection amp.

In the horizontal output stage, with this set many times I have seen the flyback and output transistor go defective. When there aer problems in these areas, most of the time the power supply is damaged.

What is interesting, is ou say that this set is about a year old. In actual fact, this model is about 5 to 7 years old.

Considering the age of the set, I would be seriously looking at getting a new set rather than put money in to this one. This model is obsolete, and many of the parts for it are no longer availabe.

The 6 blinks mean no horizontal. Check the horizontal circuitry. I'll look up your specific model later and post more details.

Sony KV-32FS120 blinks 4 times


good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.


response is highly appreciated.

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

Seven Blinks: High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into shutdown. Check power supply and horizontal circuits.
