Question about Mitsubishi WT-42311 42" Rear Projection Television

1 Answer

Convergence The vertical lines on my 42" tv won't line up. I've tried the red & blue line up- Also the grid line-up. It will let me adjust the vertical lines, but not the horizontal line. I get red, yellow and green seperated on the icon for the tv station and almost a 3d blurred screen. My tv was moved and droped about 3".

    I own a Mitsubishi WT-42311 42in rear projection tv and one day I turned it on and the blue convergence was way off. I tried to adjust and it won't line up. I tried the advance convergence and same deal. Red convergence is fine. The picture is horrible. Sound and all other functions are great. What is wrong and HOW DO I FIX IT?! Repair man said $350. I got a great deal on this tv from a friend of mine a year ago and no way am I paying 350. I'd rather throw it away! HELP!

    I had the exact same problem, my tv wasn't dropped but I did smell a slight hint of something burning the first time this problem surfaced. We did replace both convergence IC's and the it didn't correct the problem.



    Any suggestions what the next step might be? Thanks in advance for your help.

Mitsubishi ws-48311 blue and yellow shadows


I would suggest you go into the menu and select convergence and then advanced convergence (set will display on screen instructions) and call up the grid of lines by doing that---the grid of lines you see should all be yellow---if you see red or blue lines out of position try with the Mitsubishi remote to adjust them.

If they will not adjust the set needs the convergence circuit repaired.

For many if this is the issue it can be a do it yourself repair--I have complete instructions for this repair in this set---start to finish.

Look first to see if this is your problem.

Mitsubishi Rear Projection WS


5ebe434.jpg A projection television and a convergence control method thereof are provided. The projection television, which magnifies images displayed on cathode ray tubes (CRTs) for the colors red, green, and blue using lenses and projects the magnified images onto a screen, includes a convergence control apparatus capable of adjusting the convergence while an input image signal is displayed, the convergence control apparatus including: an image signal decoder which processes the input image signal to generate a data signal, horizontal and vertical synchronous signals, and a start signal indicating the start of either the horizontal or vertical synchronous signal; a convergence control unit which normally projects an image signal output from the image signal decoder onto the screen and performs convergence control using a predetermined region of the screen displaced from a visible region of the screen according to a convergence control command; and a main microcomputer which inputs the convergence control command to the convergence control unit when the start signal is input from the image signal decoder, stops the convergence control when a completion signal is input from the convergence control unit, and performs a control operation to continuously display the image signal during the convergence control.

the pro in convergence control circuit only..so better change tat..

Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synchronizing.
RP TV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Hope this will help in solving the problem....

Picture is saturated in green with vertical wavy white lines"


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.
