Question about Toshiba 50H82 50" Rear Projection Television
Saw the post requesting a soft-copy or link to service manual for 57H82. I'm having the wavy line problem on my 50H82 and thinking about attempting the fix myself. I was wondering if you could send me a soft-copy or link to the service manual for that model, or point me to a site where I could find one? Jim C.
Dont have the manual - sorry - but this is the most likely cause.
Projection TV sets have two very common problems listed below.
Problem #1) 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. 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 more information and a DIY convergenece repair kit with instructions from the link below.
Here are some of the most common problems with these sets...
*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound
Problem #2 - Another common problem is dull or washed out video.
Your set may have one or more of the following symptoms....
*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
