Yes is is your convergence IC's. One has gone bad, but consider replacing both of them because if one has gone bad then the other is not far behind. They are located on the middle board of your set. They are mounted on a large heatsink, the part # should be STK-392-040. Replace these and your set will work fine again.

HELLO . it sound like you need to replace the convergence board or just the IC'S ON THE BOARD. IT WOULD BE CHEPER THAN THE HOLE BOARD. "GOOD LUCK"

Akai replacement parts

You are not likely to find the board easily, but you should be able to replace the convergence ICs relatively easily. Look at the board. Try resoldering the pins on the STK ICs. If that fails to resolve your problem, replace the ICs. There may be some pico fuses located close by or low valued resistors that may be open. Check for those as well.

Keep us posted.
