Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

Three color dots

I have a Mitsubishi WS-55511 television and every time I turn it on there are three small color dots in the center of the screen. I assume this means the bulbs need to be replaced but I'm worried that it may not help. The dots are colored red, majenta and yellow and they are always visible when the tv is turned on.

I have a 55 inch rear projection mitsubishi tv. it recently has started showing what looks to be white spots when viewed at a distance on a dark screen. when you look at it closely it actually is red green...

It is called Convergence. You have three CRTs. Red, blue, Green. When they are not aligned, you will see the individual colors. See if you can do some alignment in the users menu. Look for Converge or Convergence in the menu. Either under video or setup.

Mitsubishi HDTV 1080, model WS-55511. Color convergence is off but only on the outsides of the screen; in the center it is fine. Can this be fixed or do I need to replace the television?

Yes, it can be repaired, replace convergence out chips (two ICs) on main board.
If you are not comfortable with TV repair or have no experience, call local tech to fix it. Cost of repair would be $180 or so.

Powers on for three seconds then goes off

The first thing to do is to try to determine why the set is not turning on. It is equipped with a self diagnostic feature. On the front of the set push the MENU and DEVICE button at the same time and hold until the LED starts flashing a two sequence code. That will narrow things down for us.

Ws-55511 power problem

Ok the 12 code means no error detected. Try this you will see three small wire plugs that run from the convergence yokes on the picture tubes. not the three big plugs, they will be real small plugs all identical. try unplugging them and then try powering up the set. But remember where each one was plugged so you can plug them back in correctly.
