Question about Mitsubishi WS48511 48" Rear Projection Television

1 Answer

Blue convergence problem

There is a blue ghosting effect that typically ghosts any text (scores, channel guide, etc) in a bow across the top of the screen. So there ends up being a blue bow from the top left to top right that sags down in the middle.

I tried resetting the convergence (I couldn't figure out how to try manually adjusting convergence) and that didn't help. From reading this board it looks like I may need to replace an IC or something, which I'm comfortable trying, but I wouldn't know where that part would be in the TV and such.

Thanks for any help - this is driving my parents crazy.

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,Pioneerblue convergence problem - 2_bing.gif 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

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Convergance issue on one AV input only


This is not a convergence problem in the traditional sense as it would effect all inputs not just one. I would be looking at the video switching IC as the defective part. I'll look up your model to try to get you more details. Are you going to attempt the repair yourself?

Thanks,
Dan

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.
