Question about Toshiba 50H82 50" Rear Projection Television

1 Answer

Http://www.fixya.com/support/t456116-toshiba_50h82_service_manual Hi, I'm sorry I'm a hvac tech and had my fair share of circuit board problems and I came to this site with some hope that I could get an honest answer to fix a 5yr old T V that wouldn't be worth the service costs to fix it. One of my good friends works at a company that builds computer components and was willing to repair the hyper board on my t.v. if I removed it with the info that I looked up on this site. The repair instructions this technition gave are useless if not destructive to the common tech. The way it sounds in his answer is you should just remove 2 screws and with some patience anybody should be able to remove this board and caps and replace them with "cut to fit" ones. From what I've seen everything on this board is soldered in, even the metal cover that's attached to the board itself. Maybe I'm looking at the wrong vertial metal case just behind the jack board, but it seems this tech either hates that other people might have a talent for the same trade, or is just an a** hole!!!!

Toshiba 50H82 Wavy Lines - Jittery Picture.


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

Toshiba 50H82 hyperboard caps


Service manual won't help much in the hyper board and that's likely the problem.. Simply remove the hyper board and open the can. Inside you'll see a number of smd caps. There are 11 10mf/16v that need to be replaced...
