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.

No picture


This is most likely your Backlight on its way out. Try looking closely at the screen to see if you can still see a dim picture if so then I am 100% sure that is the fault.

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.

the tv turns on fine, but after 5 - 30 min or so, "sometimes MORE " the picture all of a sudden go's black. Sound is ok it is 100% loose contact problem. 1 please check for any connector or print for loose. 2 in signal processor ic there might be loose. remember there is no component failure.

Black comes across right side of screen


Sounds like you've got whats called a cold solder connection somewhere in the horizontal width control circuit or a connection in the sweep section. Should'nt be two expensive but unless you have had some soldering and troubleshooting experience I would leave this on to the pros. Good Luck
