Question about Akai PT4298HD Rear Projection Television
I am having a problem with a blue line on the top of the tv that arc's downward....I tried the manual convergence function, and I see the lines move, however this blue line is arc'd way to far downward. Any ideas? The blue and green are just fine....Thank you very much for your service!!!
Use first quality IC's (no generics).Be sure to check all fuse devices-usually one or more pico fuses opens.

Most likely, 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 helps ...
