Re: sony kv32s42 trinitron color tv blinking

Sounds like a bad picture tube. Picture and bright settings cranked up for a good pic? Test/rejuv with a crt tester and/or look at the Ik signal on the crt board. A good tube has 3 small pulses during blanking. The crt cathodes are checked with these pulses, pulses too low and the jungle IC will blank the drive. If the picture fades in and out I would check the filament ckt but that doesn't support the "blinks"

I have a Sony Trinitron 32 color tv KV 2168MTJ (quite old - 10 yrs old), and the standby light blinks exactly 200 times (just over 3 mins) before it turns on. Once it is on, it works perfectly. What's wrong with it and how can i fix it?

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

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.
