Question about Sony KV-32S45 32" TV
My Sony KV-32S45 has worked great for years, no problems. Just a few days ago, the picture started disappearing. The TV turns on fine (red light flashes for a few seconds before picture appears), and will work great for about 5 minutes. Then the picture gets compressed to the upper third of the screen, in kind of a trapezoid shape. The picture is full width at the top, and only a few inches less than the screen width at the bottom of the picture. The picture wavers quite a bit during this time. This usually lasts for 2-5 seconds, and then the screen goes blank (no flashing red light though). The sound is working fine the whole time. I've read through solutions to similar problems, but this one seems unique enough that I'm not sure of the solution. I do have a service manual that I found free on the web, with instructions on how to safely open up the chassis and replace parts. I am also comfortable enough with a voltmeter and soldering iron that I feel I can do some minor repairs. I'm just not sure where to start. Anyone have any ideas? Is this something that can be fixed with adjustments or do I need to order replacement parts? Also, if this is fixable with replacement parts, can anyone suggest a good place to order from?
Lightly tap circuit board using any non conductive thing like plastic ruler or wooden stick. If picture apears then look for bad or cold solders. Resolder all Vert. IC pins.
