Question about Panasonic PT-47WX42 47" Rear Projection Television
I have a 3 year old projection tv. I just started having problems with it last night when it started showing a double image. The red is also way off center. What can I do to fix it?? Please help!! The picture on my Panasonic PT-47WX42 Rear Projection HDTV has a horizontal wave of distortion which seems to be the most pronounced at the top and bottom extremities of the screen, but is visable throughout. The colors are improperly alligned, and the convergence adjustments described in the manual do not seem to have any effect on the problem. This problem did not develop gradually. I turned the tv off with everything working as usual, and turned it back on to find this. I removed the screws that hold the screen to the main body of the unit, but the bottom edge seems to be secured beneath the plastic valance where the front AV connections are located, which in turn seems to be secured beneath the speaker dust jacket. I find no visable fasteners keeping the valance or the dust jacket in place, and I dont want to break anything by guessing incorrectly which way to yank or twist or pry, so thats as far as my repair attempt has gotten.
The problem you are seeing is a convergence problem. This is a common problem and is fixed either by resoldering bad connections on the convergence ICs or replacing the ICs. These are large black ICs attached to a heatsink and are marked STKxxx. Try resoldering the pins on these ICs first.
