Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television
The set is a couple years old. When it displays images with dark areas bordering light areas, especially with dark appearing to the right of the light, a ghost image appears along the light side of the border. The ghost consists of red stripes that appear stationary relative to the image (i.e. moving images appear to pass by the stripes) but it only appears in the area along these light/dark borders. It appears in HD and SD, as well as signals through different inputs (cable box and DVD player, both connected via component cables). Adjusting the image revision didn't fix the problem.
When you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...

I have the same problem - exactly as you described.
Thanks for the input. I'm 99% sure it wasn't caused by a static image, because it has rarely if ever had static images left on it, or been used very much (mostly just weekends and holidays). And unless I'm misunderstanding what happens with burned-in images, the stripes appear and disappear according to what's being displayed. Also, the aforementioned striping effect occurs over the entire screen, and there has definitely never been a static image of narrow stripes left on the screen. Are there any other possible causes for this?
Yes, I am experiencing the same problem. I have tried the image revison with no success.
I have had the same red/pink ghost image for a couple of years. It is to the left side of the images. If you use a smaller screen image the ghost image runs along the entire right side of the frame. Sony is no help. From having worked with microscopes and projection aligners in the semiconductor industry, it behave like a lamp collimation issue, where the lamp needs slight adjustment in its position in the holder. But there is no way to do that, that I know.
I had 1/2" red stripe on right side and green ghosting on images. A Sony tech came to my home and using only the remote, he completely recalibrated the picture using the procedure from a service buliten. He did not even touch the set itself except to get the model #. It took about 30 minutes for the entire procedure. I was charged $99 and he was gone with atotal time spent of about 1 hour. The picture is like new!!!
PS: A local TV repair shop said the set was not worth repairing.
