Hi,
I have a PCM 9375 that on book provides a POST beep code of 7 6 6 (DECIMAL) after which it emits a continuous tone. I cannot find this POST code listed. Can you please advise what it indicates.

The 7-6-6 POST code on your PCM-9375 isn’t a standard beep code and likely comes from a debug card showing decimal values. It usually indicates a serious hardware fault often memory or CPU related. The continuous tone afterward also points to a hardware failure; try reseating RAM and checking CPU connections.
