If you can quickly get to menu before picture goes blank, then go picture / backlight / set backlight to minimum and it will work fine.

Sony kv35s66: No picture, just sound and red blinking


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.

Keep us posted.

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,

Sony kv35s66: No picture, just sound and red blinking


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.

No picture just comes sound


sounds like the Backlight has failed, if you look closely at the screen you should be able to see the image changing, but as there is no back light there is no luminescense so it will appear black or grey, It is probably the backlight inverter or element that has failed, if this is within warrany organise with them to fix it for free,
