Question about Toshiba 42H81 42" Rear Projection Television

1 Answer

Colors separating...convergence issue

I have a Toshiba 42H81 purchased in 2002. The colors now separate and some wrap around...looks like 3-D. The repair quotes I am getting are outrageous (in my opinion...Best Buy wants $150 just to come out, another tops out at around $350). Please, we can't afford such nonsense. If someone hass a less expensive solution, it would truly be appreciated.

If you have any electronic soldering skills you can replace the convergence amp IC's which are part # STK 392-110. Buy the expensive IC's which are made by Sanyo and they last longer.You can buy these from www.encompassparts.com for about $30 each.
Buy some desoldering wick from radio shack to assist in removing the old IC's.

My Toshiba cinema series HD separates the red & blue color.


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.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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 Model # 42H81 Picture Problem


Can you describe the issue a little more? It may be a convergence issue which is quite common on big screens. But there are quite a few issues that can cause a bad picture.

If it's convergence, you'll be able to tell by going to a news channel and looking at the text. If the convergence is bad you'll see a ghosting like image of 2 or 3 letters for each one that should be there.

Red & Green seem "off centered"


Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.
