Question about Sony FD Trinitron WEGA KV-34HS420 34" TV

Sony Trinitron KV-32XBR37

My TV turns on fine and the picture is great except it blinks on and off. It started about a week ago and it seemed to only occur about once a minute for the first 10-15 minutes. Now it is happening more frequently. The picture goes out completely when it flashes off and then comes back completely. Is this something that can be fixed easily? Any ideas would be greatly appreciated.

Thanks,

MK

    I have a 32" sony trinitron wega kv-32xbr250. When I turn the tv on the picture comes on for a minute or so then the picture goes black for a second. There is sound all the while. The problem seems to be getting worse. I have unhooked the cable and tried another tv and had no trouble. Could you suggest how I could correct this problem. There is no service in this area.

    I have a 32" sony wega kv-32xbr250. The problem I have is the picture goes on and off and now it goes on and off more regularily. Is there anything I might be able to do myself as there are no repairman for 500miles. I have hooked a older tv to my cable and have no problems.

This may be a bad crt or picture tube. Take a good look at the picture when it's on and see if it has a pinkish or greenish tint. This is easiest to see if you turn the color adjustment all the way down. If it looks like the tint is green or pink and the focus isn't great then it's probably a bad crt. Not worth repairing if its the tube.

No picture or sound


6 blinks usually means a loss of the horizontal signal. This can be as simple as a bad capacitor or jungle IC. I'll look up your specific model, but do you intend to repair this yourself? If so, please update this and I'll provide additional details and instructions.

Sony 32" trinitron kv=32fs16 tv problem.


I had the same problem 3 years ago. I called in a Sony tech and he said this was a common problem with this model. He replaced several resistors and resoldered several "Coaled Solder" connections. The repair ran $187 but the set has run great ever since!
