Not exactly familiar with this model but sounds like the projector lamp is burned out. Hopefully it's a replaceable type. Try calling these people - http://www.purelandsupply.com

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.

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 projeciton 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 photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

SOURCE: bottom 4 inches of my

LOOK AT ATTACHED PHOTOS AND TELL ME IF THEY LOOK FAMILIAR.

THE MODEL INDICATED USES TWO of the STK-392-570 CONVERGENCE CHIPS.

I have step by step, start to finish instructions for this repair in this set. It involves getting the middle circuit board out of the set and replacing the two chips.

Total parts cost on EBAY WILL BE UNDER 25 DOLLARS AND repair takes on average about a hour--I have done hundreds of these sets and if you are doing it for the first time it may take longer.

The instructions tell you everything you will need and how to do the repair from start to finish and they are free.

If the information helped you, rate this solution as "very helpful: as I do this here for free.

If you want the instructions let me know and I will post them here for you for free. I will assist you from start to finish if you attempt the repair.

REGARDS, SD TECH

Why do we have sound but no picture?


This is an older picture-tube projection TV.
There are just a few things that can affect all three color tubes at the same time. One of these is "Blanking" and the other is the High Voltage.

Blanking happens when there is not a good signal to the TV, and the high voltage and therefore picture are shut off to protect the high voltage system. Make sure there is a good, strong signal to test it from, like a DVD player, otherwise the TV could blank off from low signal levels. A signal good enough to produce sound may not be good enough to keep the picture on, so that is not a good indication of good signal.

The other, High Voltage, is complicated and dangerous to work on and best left to a qualified technician to work on. High voltage in a TV can hurt or even kill you if you get across it.

The Color On My Mitsubishi Rear Projection Tv model- WS-55908 looks to be off, picture looks blue and Yellow.


its sounds like the convergence on your TV needs to be adjusted. (this adjusts all of the color guns in the back of the tv to line them up again, when they get off, you start to get yellow blue or red halos around objects in the picture. In the setup menu on your TV under picture or Display there will be an item that says "convergence" follow the instructions in there so all the crosses on the screen no longer have colored halos anymore.

Mitsubishi HD 50" rear projection tv is only showing picture in black and white. What is the problem?


Is sounds like to need to go to SETUP and set the unit to color. Also, weak signals will cause the unit to switch to B/W. Try using OTHER inputs (like DVD) to see if you still have no color. If no color, it could just be a SETUP problem...or..(ugh!) you have lost your color wheel or related circutry. (no easy fix)

Mitsubishi Diamond Series T.V.


When a tv (Rear proyection) shows this coloration is the meanning that the red color is not there (the red color is generated by a red CRT). Now it can be really bad not having the tube working but before conclution make sure of this: (and if the red color gets back then the tube is ok)
  • is this condition the same in all inputs? or the picture looks ok with a different video source (VCR, DVD other)
  • are the menu letters same as the picture looks or are they fine?
If we cannot see any red color back with this testing, still chances that a technician find an electronic problem that make the tube to be off. so don't rush conclusions and get to the end to save the tv with out replacing the red tube, but if all was done and nothing then the tv needs the tube replacing.

Tv lost color


Your problem most likely is on the signal board is my guess. If your not a technician it would be in your best interest to have him check L2C60 on the signal board.
