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

We got our mitsubishi in 2000. it was working fine and then little by little the picture has wavy lines and you can't see the movie, it has gotten much worse. what can we do?


The wavy lines are caused by the aging of the vertical deflection unit = the defective parts (some capacitors and resistors) must be replaced.
The fix wont be very expensive - the parts will cost less than $25 - but you need a good electronics repair guy to do the job and this is going to cost you.
Remember, it's an old tv that has started to show its age. Maybe it's time to start saving for a new one.

Toshiba rear screen projection tv theaterview colors wavey? It no longer is visible, the colors are separated


1.) It sounds like you have a convergence problem; in the customer menu with the original Toshiba remote select convergence--if blue or red will NOT move in some direction you have a bad convergence IC.

2.) This set uses 2 STK-392-110 convergence chips; they and any open resistors around them need to be replaced and the set adjusted.

3.) If you are able to do this repair yourself you can save a lot of money--Most TV shops will charge 300-400 for this type of repair on this set.

4.) If you cannot do the repair yourself look in your area--now is the slow time of year for TV repair shops---if they say it "has to go to shop" keep looking----almost any good tech can do this repair in your home in about an hour--I have done hundreds of them here and charge 200-250 total depending on brand and model.

5.) I am here to help people and if you have questions or need advice let me know--the two chips this set uses you can buy on Ebay for about 12 dollars plus shipping.

I do this here for free, so if this information has helped you give me a vote here---let me know by replying here if you need more help.

Blue Flickering Screen - Which Repair Kit?


yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.
