Question about Sony KV-36XBR250 TV
It looks like this might be a common problem, but my Sony 36XBR250 tv has worked great for 7 years and now I try to turn on the TV and I get great sound from both cable, satellite and DVD, but no picture. The red blinking light just blinks once a second with no pauses. I can't seem to make out a pattern for a diagnosis code, so I belive it is just a blinking light telling me to service the TV. Does anyone have a remedy to the problem. The TV is too heavy to take to the TV repairman and I think they will charge me an arm and a leg to come to the house. Please help!!! Joey
This is a common failure mode (which I now share), and has nothing to do with the picture tube or surge protection. From the forums I have searched to-date, it appears to be a failed component in the flyback circuitry, but Sony will not admit to an inherent defect. If anyone has ACTUALLY FIXED this problem, please post a reply. Guessing won't help anyone. Thanks.

Sony has a problem with a lot of their sets-namely,poor solder points.I bet that is your problem.Circuit board has to be inspected for cold solder points,especially around the flyback transformer,which supplies most of the operating voltages.

I have similar problem. But after a few minutes of standby light blinking, the TV audio went on, but no picture. I then turn the TV off and back on, then I get both audio and video. The duration of blinking varies from 2 mins to 60 mins. Anyone have any idea?
Thanks in advance.

It might be surge protection (though if you get audio it might be #2 - see below), try unplugging the TV from the electricity for 5 minutes and see if it helps. 2. If the above didn't help, than it's probably the tube which might be done for (7 years is a respectable time) in which case you might be better of buying a new set (tubes in the majority of cases cost a lot to replace).
