Pin 10 should be at the positive convergence power voltage. The ICs run on a plus and minus voltage from a power supply. Usually +/- 15V to +/- 30V. (don't know this brand.) (not sure if -570 is replacement for -560; could be.) I'd look through main power supply for these 2 voltages. Ohm to pin 10, etc. Check PS fuses there.

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.

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.
