Question about Sony KDL-55EX640 55" Bravia LED 1080p HDTV with Internet, Wi-Fi Adapte

1 Answer

All of a sudden there is green dots (snow like) all over the screen/picture. Just bought this tv about 2 weeks ago, and it was working fine until last night. When I turn off the tv, wait a littlebit & turn it back on, it works fine for about 30 seconds and then the green dots appear all over the screen. Mainly in dark areas (black). What can I do top get rid of this issue? I tried turning the tv off, waiting for like 30 minutes & turning it back on. I also unplugged the power cord of the tv & plugged it back up, same result. I even reset the tv to manufacturer settings, but still I turn it on & 30 seconds later the picture is covered with green dots in certain areas (depending on the color). Help, please....this tv is basically brand new & it's still not working right. Sony customer support wasn't very helpful either, they couldn't help me fix the problem. Does anybody have the same issue & how I'd you fix it?

SOURCE: Sony TRV-19 Camcorder - Black screen in camera mode

Fixed it, at least temporarily I had the side off my trv250 examining it, especially the CCD connection. I had read the post about soldering a capacitor to pins 1 and 3 (from the left) on the bottom row. I didn't have the specific capacitor on hand, but I started touching some of the small ones I did have to those pins. I found that after I touched a 100uF, 10V cap to pins 1 and 3 the picture suddenly came back to life and stayed that way after removing the cap. I have no idea how long this will last, and I've set up the cam on a tripod in the livingroom with the LCD display facing me so I can monitor it. If you, like me, figure you have nothing else to lose, you might want to give this a try. Note: my camera was suffering from the green smeary horizontal lines problem, and wasn't completely black. I'm not sure if this makes a difference or not.

I have the same TV which had the same issue ( green in picture ) - back on 10/2007. I called Sony. They had their technician replace the optical box ( factory defect ). There was no charge for the repair even though TV was out of first year of warranty. Call Sony.

There is a fault in the main processor that is causing noise. The set will have to be serviced. The tech will probably try the main video processing board to start.
