No picture; black screen; only red light blinking.
Almost 9 years old - worked great until yesterday. Sometimes if the TV is moved around, will get snowy screen and then cable stations come back. Removed old cables and attached new ones, but this did not help. Something must have come loose inside. When it works, sound & picture still great. What would be the approximate cost to repair?? Or better to discard and purchase new one?? Thanks much.

I had the same part replaced in my KDF-42WE655 (3 YEARS OLD) television about 6 months ago and it was covered under an extended warranty by Sony because of a defect found in the part after manufacturing which Sony found will malfunction after time causing multiple issues with the television. My issue was the bottom of the screen started to get a blue dot that was getting progressively bigger. I bought the extended warranty from Best Buy and the problem was fixed no charge but the technician told me that Sony is aware of this issue and they extended the warranty on this part because of it. I would start by calling Sony and letting them know of this issue and see if it's covered under this extended warranty. Hope this helps
The TV is in protection mode. An internal problem was detected and the set shutdown to prevent further damage. If the set is only 9 months old, it should still be under warranty. Call and request warranty service.
This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.
The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.
Your lamp has most likely blown out. that is what happened to mine and once I replaced the bulb it worked just fine. this is one of the cheaper stores to find a replacement bulb, www.bluestar-online.com
