Question about Toshiba 55H70 55" Rear Projection Television
The blue layer of the screen is warped leading to a seperation of the viewing image. I was wondering if anyone had any suggestions, I've heard that it may be a convergance IC. If it is I would like to know what part I should order and maybe where I can find it on the TV board.
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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.
