SOURCE: Sony KV-36XBR250 - no picture, good sound

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.

Hi,

Your receiver is the Denon AVR 2105 and not the Sony STR-DG510 5.1 Channels Receiver?

SOURCE: blinking picture

TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.

The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.

He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...

SOURCE: HDMI port does not work on the KV-30SH420

I dont have a TV with HMDI input but i do have a computer moniter. To change i have to press a button that changes from VGA to HDMI. My computer supports HDMI and when i tried it, it works. Try looking in your manual for a way to switch input methods.

just try unplugging it for a little bit and see how that works.
