Hello all, I purchased a used DM4800 around 6 months ago and have been loving this thing. Today when I turned it on I was sad to see a message pop up with no way around it.. Mixer Device Boot Failed (DSP-A SRAM) I am unable to get into the board's diagnostics mode so I can't reset the SRAM. From what I understand the problem stems from the Main Board (E902855-00B) and more specifically one of the DSP chips that is on that board that I assume is used for the onboard effects. Not entirely sure if I'm correct on all that, I wasn't able to find a whole lot about this issue from my research, so correct me if I'm wrong. I found the main board on ebay, is it as easy as swapping in a new one? Wondering if anyone else has had this issue or if anyone knows a fix. Any advice/help would be appreciated Thanks!
