Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

The R, G and B guns on my rear proj tv have gone out of alignment and I am unable to re-align them. I suspect a major control board has gone south forever. Is it worth fixing?

Your symptoms sounds like it may have damaged convergence IC’s.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.

You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair

I hope this information allows you to resolve this issue.

Tv works but picture color is off and its kinda dark looking there is no duel image so i know the color tubes are ok but there is a problem it almost looks like someone took a magnet to it


You have two problems, you have a convergence problem, the convergence board needs repair, and the other problem is the coolant needs change in the guns, (CRT's) and you are looking at 500 on repairs, you would be better off getting a new LCD.

The guns are out of alignment so its showing in shadows, so how do i get them back align?


Hi,

The first step would be to use the original remote to fix the convergence problem. You need to go to menu > convergence and then try to align the convergence.If you are unable to fix the convergence by remote, you need to open the TV and replace convergence IC's. This is a simple fix.

If you have an electronics repair experience and would like to repair the TV yourself, revert and i would guide you how to replace the convergence chip on this set.

Let me know,so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Blue Projection Gun


It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

The board sits up high above the larger boards....one screw &
