Question about Akai PT4298HD Rear Projection Television
I'm a newbie to this board and this is my first HDTV. I recently purchased a used AKAI PT4298HD and everything has been awesome until this morning. The picture looks like it's in 3D with only red and green colors showing. You can still make out a picture. Is my tv toast?? I can use any advice you guys can give me!! Is this an easy and inexpensive fix?? PLEASER HELP!!
Be sure to check any/all soldered-in pico fuses in power supply circuitry.Also,STK392-040 IC replacements should be first quality== I use Panasonic with no re-calls.

This is a convergence problem. From your menu, go to Menu, Function, Convergence and then use you remote to try to adjust your colors. If you can not get them to line up this is a problem with the convergence board. The convergence amps (STK392-040 x 2)are internally shorted. These can be replaced or the whole convergence board can be replaced. It's cheaper to replace the amps, but more convienent to replace the board (especially for the less electronically inclined!! :) Hope this help you out....
