Question about Mitsubishi WS-55805 55" Rear Projection Television

1 Answer

The Green Shadow...

My 6 year old Mitsubishi 55” W.S. HD 1080 Projection TV has developed a green shadow around most everything on the screen. This has become very annoying! The only adjustment I can find on the remote is for the blue & red and the factory default convergence setting has little affect. I “want” to remove the back and see what I can find, gun adjustment, settings, cleaning, etc... But I thought I would ask if someone knows of a repair manual or instructions available for a Tech Savvy, but no TV repairman, person on how to make these adjustments? The HD on this unit was UNBELIEVEABLE when I bought it and I really miss it!! I really don’t want to haul this ½ ton crate to the repair shop so if there is a way I can work on it myself PLEASE let me know!!
Oh, is there a way to remove and clean the front screen as well?
Your help would be most appreciated!!

    I also have the green shadow that was fixed when turning on IRIS, however even doing that doesn't help anymore and when I adjust the sharpness there is no change to the picture, so I believe if I can fix the sharpness issue it'll solve the green shadowing...Help Mr. Wizard..help!!

SheriDans, I am not an expert or a TV repair person but I do have a WS-55805 like yours and am trying to repair mine. But in trying to do so I did figure out how to remove the screen. So If still want this info here it goes:
Remove the speaker cover by pulling at the left and right edges. It is held by pressure pins. You'll need a philips screwdriver to remove 7 screws. First the 4 screws that attach the cover that is between the speakers. Now follow the wires that come from beneath the center of the screen and into the TV. These wires will be attached to 2 plugs before it goes all the way into the circuit board. Disconnect these plugs. If you notice on the underside of the screen that was hidden by the speaker cover are 3 screws that hold the screen in place. Remove the screws. To remove the screen you'll have put your chest against the top of the screen and put your hands at the bottom of the screen, right hand at 5 o'clock left hand at 7 o'clock, more or less and push up gently. This will release the screen from the clips that is holding it in place at the top. Now you can grab the screen from the sides and remove it completely.
To replace the screen remember to position it an inch or two above the top of the TV and let drop slowly.
Hope this helps.

most likely the convergence Ics have failed. Check F9a04 and F9A05 pico fuses if they are blown you will need to replace them and the convergence Ics.They are located on the center board they are green and look like resistors without the color band. see the photoa193b32.jpg82b89b8.jpg

Your television needs convergence adjusted. Seek your owners manual to do this.
If you need help locating it, let me know.

Problems with my Mitsubishi hd1080


If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad.
I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced.
I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's.
Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability.
Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat.
If you are a "do-it-yourselfer" here is a link with the directions and pics.
