Re: 55 apex HD tv

The APEX and most rear projections are notorious for poor solder joints. The convergence circuits on your TV get very hot and the solder joints weaken over time. In your case, the convergence STKs are the large chips mounted to heat sinks right up front on the left hand side circuit board. Remove the board and resolder the STKs using a good low wattage iron. If this doesn't fix your problem try replacing the STKs. They aren't that expensive. They have 15 or so legs so you'll need some skills removing them. Good Luck!

Blurred picture red and blue shadows

Please run the convergence feature on your TV. Its giving you double image because the red, green, and blue guns are dis aligned. By running convergence it will realign the guns properly. You need to run the convergence feature at least once a week. Please note this is only for CRT rear projection TV's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to refer to the manual on how to go about it
Good luck!

55 inch mitsubishi rear projection tv red lamp out of adjustment

Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

The Green Shadow...

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.
