SOURCE: Mitsubishi rearTV has intermittent wavy lines running throughout

Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

This is a picture of the DM Board in your TV. The wavy lines are tell tale signs of a failed capacitor. The capacitors are the cylindrical components on the board. One or more of them have failed. There is also a FMT Board with capacitors that could be causing this also so test them all. The DM board alone is 1000 bucks so it would be well worth it to invest in 50 bucks worth of capacitors and change them all out. Your boards would be fresh and good for another 4 years.
Your other option is to call a TV repair man and he would come pick up your boards and bring them back to his shop and test out the bad 3 dollar capacitor and swap it out and hand you a bill for 500 bucks.
Hope this helps you out.

Basically i have an older rear projection model mitsubishi not sure of the model #, it is currently having lines run from top to bottom like waves on the picture screen! is there anything you can tell me...


Many different mitsubishi's have problems with voltage regulators going out and causing wavy diagonal lines that scroll the picture from top to bottom or vice versa. Without a model number it's difficult to clarify.

I have a samsung 65in hdtv rear projection and the colors dont line up it looks like triple vision what could it be


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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

I've worked on a few of these sets and have found C2P08 to cause something like rolling bars in the picture and have found C2P05 to cause lines jumping in the picture.
