Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
I have a Phillips Model 60PP9753/17 projection tv.I have the top and bottom of the screen bowed inward toward the center. I read the article on convergence and set manually the convergence.The color is corrected but that is when I could see the bowing. Do I need to replce the entire ACS board or is there something else I need to do. I have the phillips service manual and have some skills.
Projection sets have two very common problems outlined below.
The first common problem is convergence
These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.
When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.
Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.
You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.
Here are some of the most common problems with these sets...
*Screen Looks 3-D
