Blue convergence not adjustable on AKAI PT4298HD. "Red" was out too this morning, but could be readjusted with the remote control, but not the blue.


hello idagostin more likely you have a bad stk convergence amplifier or i could be some loose connections, remember when you have to replace both of them and check for any open resistors
thanks and good luck

your tv is having convergence problems if you can't adjust it out with the customer controls you  probably will have to have the convergence circuit repaired witch should cost about $300

My tv


If the colors are red,blue,and green, then look for you convergence controls in the menu or off remote. If problem is more intense, then the convergence amps maybe needing soldering or replacing.

My Picture is in Red and Green??


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....
