SonyKV35v36Sony picture goes out every 15 to 30 minutes, but the sound stays on. Then I just turn it the set off, then it on, and it stays on again for 15 to 30 minutes. Often these errors are related to a bad solder joint on the main-pcb or crt-board. You can check this by [b:5e367dc780]gentley[/b:5e367dc780] tapping on some parts on these pc's with an isolated screwdriver. Whenever you tap, and the picture goes dark, you're sure it's a bad solder joint and you'll need to re-solder it. 04-07-05
