Ok i've had intermittent sound for awhile but now i have none.. some channels got fuzzy and now nothing...
Heres the back story. This cab had been waterlogged bad, bottom foot of cab was replaced. At that time i rebuilt the mcr, replaced the ribbon cables, scotchbrited the fuses and all was happy..
Over time sounds started dissaappearing or having static in them. I found that if i wiggled the connectors at the pcb or at the amp sounds would come and go. SOund bard was reflowed. I basically made a while new shielded harness between the pcb output and input of the amp board.. new wires and connectors. no diff.. also while i was working on this sound issue all of a sudden the graphics got krappy/sprites, pcb started only getting 4 volts. also Lost monitor power..
I fouind that the 3 fuse fuseblock had basically crumbled apart.
I replaced the fuseblock tonight. Reseated all the pcb ribbon cables again tonight.(they are new bob ronerts ones) Powered up.. monitors back, graphics are now error free, but still no sound... none in selftest either. SOmetimes on powerup i get a "sound board interface error", whatever the hell that means..
Have any of you guys been down this horror-path and if so what all did you do to correct your issue? stupid 25 year old wood boxes.....
