Question about Philips 55PP9753 55" Rear Projection Television
My set has blue ghosting along the outer 1/4 screen (both sides) with the center 1/2 looking normal. I'm able to converge both the blue and red single points (fyi, both are good). The multipoint red is aligned but the multipoint blue is WAY off on both sides.
My problem: I can't converge the multipoint blue settings. The + will not move left/right but will move up/down.
Is this indicitive of a bad chip/board/circuit? Any idea of the cost to repair if I go to a shop or if I can do something myself?
The most likely cause is shorted convergence chips and possibly a few pico fuses.
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. 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 and others.
You can get a convergenece repair kit with instructions from the links below.
