Sony Trinitron KV32S42 Picture Blinks on and off 60 times per minute

Hi there Jomaru, I also have the same set and experienced the same problem, Never recieved a true fix . But,What i have found is that if you remove the Video fiie cable from the KSB And re-seat it, it seem's to solve the problem. At least temporarly, The problem has not re-occured on my set. I hope that have the same result.

I have looked on the net for a similar problem. It seems a common failure but yours is slight. If you can use a voltmeter and can find where to check voltages, then try to find a (low) voltage which is going lower periodically. You may be able to hear a relay clicking where the trouble is. The cause which is common to these sets is probably a bad soldered component. Use well insulated finely pointed probes to avoid shorting anything.

You can find the date of manufacture in the back label,if the set is a 1990 maybe then is not worth repairing but is only a 2002 set is only 4 yeras old and the set has most likely a good picture tube,the symptom you are giving us does not indicate a bad picture tube,you should get a second opinion ,it might something as simple as a loose conection in the horizontal drive transformer.Let Us know how it goes or if you need more information.
