Sony KV-32S40 32" TV problem

I have this Sony KV-32s40. its about 5-6 years old and its been working fine until last year. It started off just turning its off while watching the set. So we took it to the repair guy and he let it run all day until it will turn off itself but it never did. So, he said he didnt see the problem. Took it back and it did the samething. took it to the repair guy and he said nothing wrong with it. took it back and been running good until this morning. Now there is No Sound and No picture. But you do here the click noise when u turn it on and the standby red light flashes all the time. What should i do? I opened the back to see if it was dust problem and cleaned it out with those air dust remover cans. Didnt do a thing. What you guys think is the problem?

    how do i pulled the board to re-solder it, is there a safe way to discharge the tube? i do have some electronic schooling. but not tv repair. it is doing the same thing, i can hit the side of the tv and it will pop-back on, i do have sound, when it's starts losing picture around 10 to 20% then the picture shuts all the way down, i guess this is some type of shunt to protect the tube, help

    thank you paul2982@yahoo.com

I have a KV-32S40; it also has no picture, no sound, and the red light also flashes.
I called a local service man - he claimed that the nonstop flashing light indicated a bad tube.

Intermittent problems can usuall be liked to bad solder connections. And sony typically has some that will develop after a few years in the power supply. so check for bad sodler connections throught the main board & give a close look to the power supply & check you work after to make sure you have no shorted pins. good luck.

I have a ten year old 37" Sony XBR TV that works fine until you turn it off and then go to turn it back on. The picture does not come back, but sound does. The only way to solve this is leave it off...


most likely it needs repiars, (replacement of capacitors in the power-supply.)primary and secondary side.
Or loose conections (dry joints)

Sony KV-32S45 turns on at first, than blinks out, still sound


I would look for intermitent solder connections on the small horizonal driver transformer as well as other HV Componets.(HV Transformer etc.) Also solder up the Vetical output IC. These have been common causes of failures. I would not use the set until these have been checked and soldered. If you don't, a massive failure of the hoizonal circuit and powersupply will occur.
Hope this helps,

My sony wega keeps cutting off then coming back .


a couple of years old can be a long time:

has the TV been on 24\7

It's the amount of hours that matters..

electrolytic capacitors typically last 3000 to 5000 hours....

Special "long life" caps last close to 7000
but the caps in most consumer electronics, even broadcast equipment 3-5K hours.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Sony tv snow for first 5 minutes on


Probably dry solder joints in the tuner section.

When the set warms up, the faulty joint/s make contact, then lose contact again when it cools down.
