I'm troubleshooting an EBD. The machine plays, but I have a couple problems I haven't been able to track down yet: The sound is only a garbled heart-beat sorta sound and the displays have some distortion (extra or dimmed segments occasionally). The caps and ROMs on the sound board have been replaced with only little change in the sound. I've noticed the SB LED seems to flash with the sound.

The MPU was replaced (with AllTek) because of corroded battery and bottom of board. While the old board still functioned, adding the new one had no change on the sound (as expected)

I've started to think it may be a power issue and wanted to confirm if the below are the expected readings at the TPs of the AS-2518-54

TP1 - 6.4VDC
TP2 - 230VDC
TP3 - 11.9VDC
TP4 - 6.5VAC
TP5 - 43VDC
