I have a Mitsubishi projection T.V that turns off after I turn it on. Before this started happening the edges of the screen would look bowed like 3-D. Can you help to tell what is wrong and how to fix it?

Projection sets have two very common problems outlined below.

The first common problem is 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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.

You can get more information and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Picture Bowed towards the center


It is a convergence problem, probably one of the convergence ICs has blown and must be replaced. Call the number in the last pages of your user manual to get repair service in your area.

Bowed picture with color divergence


Hi, The Mitsubishi TV set you have uses two of the STK 392-570 convergence correction IC's. These IC's can be purchased from here http://www.mcminone.com/search.asp?keyword=stk392-570&btnSubmit.x=6&btnSubmit.y=7 These are the original Sanyo replacement type IC's. No aftermarket cheapo ones. Unfortunately this board that the IC's come on is part of the main Printed circuit boards. If one was available for a replacement, it would cost in the range of about 400 bucks. The way it sound that your TV set is intermittent, is that the IC's are not bad, but need to be simply re soldered. This happens a lot with this model number or set of convergence IC's. To tell you the truth, I have had to replace these types of convergence IC's very rarely. Mostly when the set come on with bad convergence and does not change. Find a friend or a neighbor who can solder, find the black STK392-570 IC's standing up against a large metal plate, turn over the printed circuit board and resolder all of the pins, just double check all of the solder points for solder bridges. Good Luck
