Mitsubishi WS-65511 Red and fuzzy picture

All of a sudden my TV has a deep red hue on the screen and the picture is not well defined. I tried the convergence reset (to factory settings and a manual reset) but no change in the picture. Any suggestions? Thanks!

    No, I do not see any blues or greens and would not call the fuzziness in the picture 3-D effect.

    Problem turned out to be anti-freeze from the red tube that dripped onto the ckt board. Tech cleaned off the ckt board, removed/resoldered 3 capacitors to make sure all anti-freeze was cleaned off, and put a small plastic shield over the board to prevent any future drip from hitting the board. Fixed all in less than an hour. Thx for help.

Sir,

First u look for bad connections on the convergence ICs. These are large black ICs attached to a heatsink. They will have 15 pins or so. Resolder all of these pins and report back with your results.

Also Sounds like you have cold solder joints, or solder joints on the mainboard which have cracked over time due to thermal expansion and contraction of the circuit board.

Repair is to find and reflow the cracked joints. You may want to consider hiring the services of a reputable repair professional to deal with getting your set back into normal operating condition.

In the meantime, stop using that TV in its current condition! Continued use in that state could make the problem worse or create new headaches that may only allow for a more expensive repair bill.

thanks
good luck

Let me know do you see Green and Blue colors in picture or they just disappeared?
Does picture give 3D effect ( 3 pictures) If yes, its convergence failure.

    OK, Its issue of over gain of red picture tube in this TV.
    Let me know, do you want to repair it by yourself? If yes, you should have TV repair experience, knowledge of electronics and good soldering skills.
    upon then I will provide you service manual of WS-65511 to carry out repair.

    hummm, its not anti-freeze, it calls coolant oil and its very necessary in rear projection CRT to keep its surface cool.
    You need to put coolant oil again at CRT surface and TV tech will do the job. Please do not use TV mean while as it can damage red crt permanently.

Would you like to bypass, defeat or reset your Mitsubishi 65511 HDTV Parental V-Chip parental lock? Have you forgotten your V-Chip passcode or password?

If you forget your V-Chip passcode, you can view the locked TV without entering your password.

When your passcode is requested, press the number 9 and the QV button on the original TV remote control at the same time. This process temporarily unlocks your TV.

When you enter the V-Chip Lock menu, pressing the number 9 and the QV button on the original TV remote control at the same time will delete your old password and prompt you to enter a new passcode. Pressing HOME at this time will cancel the entire passcode.

I hope that helps.

My picture getting dark red and moving slowly to the left. My manual is missing and I can't remember what to do.


Ok I have found you a user manual. http://www.retrevo.com/support/Mitsubishi-WS-65511-TVs-manual/id/276ci860/t/2/

Below is the service manual. http://www.eserviceinfo.com/index.php?what=search2
I cannot be sure, if that is something that simply needs resetting or some problem. However I suspect that there may be a problem with the Color Wheel or Alignment. Of course it may be a filter. have a look through the service manual and run through the set up again. This may fix the problem. But I wonder if it will be that simple, we can only hope.
