Sony KV-34HS420 Random Shut downs

You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

if you have the circuit diagram of your tv,check the horizontal polarisation IC closer to the line transformer and replace it.If it doesn't work,send the question again.

tv won't turn on red blinks 5 times , some times it will turn on like every 3o04 days

normally this is because of a failed capacitor or two that is located on the power supply board. replacing the power board in this unit will fix this issue.

That is an error code that tells the tech where the problem lies. It is probably somewhere in the power supply stage. Your best bet is to take it to a TV repair shoppe and let them deal with it. They have all the documentation in order to repair the unit, and they can tell you what the problem is before they work on it.

Cheers

Sony FD Trinition Wega KV-32HS510 Try to turn tv on -it starts then shuts off -stand by lights keeps flashing. Memory stick light flashes then goes off.

Hello there,
7 times blinks shows that Horizontal Deflection Circuit doesn't work properly.
I think, its not big fault and can be resolve in low cost at nearest Sony repair shop.

KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.
I have a similar problem . mine blinks 6 times or 7 sometimes also,and comes on with sound ,no picture for about 2 seconds then shuts off. Anything?
