Issue is with MK t-unit. The sound is messed up. I get the initial chime on boot at the rom check screen. After that there is no sound at all. Occasionally there is a garbled / strange beeps/screeches when playing but it is sporadic. On my diagnostic screen the sound IRQ detect is okay, but I get no tones on the test.
Voltage from PS/ 50K pot/ ribbons-cables/ and all game roms are good. I even tried switching out sound roms from a working Y-unit sound board to see if it would fix the problem, but no good. Caps on sound board look fine, all traces look good and I do not see any discoloration or burned components.
Anyone have a similar issue? Unfortunately the Yunit sound board itself can not be used as a replacement because of different components.
Any help would be appreciated, thanks!
