3 Answers

Picture Problem I have a Mitsubishi 1080 series TV Model WS-55805. The picture is starting to convex and I'm seeing all 3 colors of red,blue, and green. Any suggestions on how to fix the problem? Is it something that I can do? or will I need a TV repair person for this? If so, how much would something like this cost?

    I have the same problem and I don't know what to do about it. These TV's cost too much for this to be happening in a a 4 your period.

    I have also recently developed this problem. I purchased my TV used 2 weeks ago and it looked great until last week. it almost seems that you are seeing the picture in 3-D, only mine it at the top of the screen. I used to work for a home theatre reatiler several years ago and sold, installed and set up convergence after TV delivery. This was the first thing I tried to do since the tv was recently moved to my house. This seems to be a convergence problem no doubt but it is not going to change by setting the convergence. Does anybody have a solution? Any help would be greatly appreciated.

    Add another consumer to this list. I've had mine for over 6 years and begining to experience the problem now. Auto convergence did nothing for me. I took off the back and vacuumed out all the dust (not really to dusty), still no real improvement. Seems to me that some electrical part is wearing out. So now is it better to have this repaired or buy a newer T.V.?

    Mine is about 6 or 7 years old and looks like 3-D. Color alignment problem. It looks like the convergence is out but curves from top to bottom. I make a fist and hit the TV frame on top near the corners, sometimes on the sides and it often fixes it but it's annoying to have to do this. Once the TV is working fine we just leave it on all day so we don't have to pound on it again.

Make a fist and pound on the outside frame at the top corners, both on the top and sides, sometimes in the middle. NOT the screen itself but the frame. It knocks the convergence back together. Sometimes it changes the direction of the convergence problem but if you hit it in another area it will straighten it out. This will not solve the problem forever but will work for about a day. I do this everytime I turn the TV on. Best part - It's free. I'm just milking as much out of my TV as possible until it dies and I buy a new Plasma.

There is a Convergence option in the Menu under Advanced Options. It allows you to set the colors so they line up. I've had my TV for about 6 years and I need to do it every week or so now.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

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.

I have a Mitsubishi HD 1080 55


Your unit has some sort of Thermal problem either with the PSU fault, or a thermal problem elsewhere that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. T

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

I have a WS-55805. Was working great, then suddenly no picture, just audio. When I press the Menu button, I get the menu but I see three separate colors for each menu item. Could this be the lamp, or...


This TV does not have a single lamp but a set of CRT tubes.

If you get menu displayed on wrong clors or colors are not matching then it is either a bad CRT, a bad CRT high voltage power board, or sometimes a problem with convergence board and convergence ICs, however in this last case you usually get no picture and no sound .
