Toshiba 42H81 42" Rear Projection Television Logo

Anonymous Posted on Jan 31, 2011

I have a Toshiba 42H81 42 in. Rear Projection Television. The picture has shadows like you would watch a 3D image without glasses. I ran the focus on it and the vertical red has noise in it and at the end comes up with an error written in red that I can't read. Is there anything I can do and how much the repair would cost? Thanks

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors

sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

Convergence problem

Replace the Convergence amplifiers. Mine did the same. It was like watching a 3D movie without the glasses. It is not hard to do for someone who knows their way around a circuit board repair. Otherwise call a reputable service shop.
