I have got 2 carnevils, one has a dull picture and thats a board fault and no idea of the cause and the 2nd all passes initial diagnostics but then reports DCS2 0BAD and if you do a sound subsystem diagnostic then it cant even read the OS version and things like PORT BAD, SRAM UNKNOWN etc. Board plays fine, good picture and shoots accurate... any clues as to the likely faulty IC or component as have a doner board and can rework no problem.

Thx
 
I believe there's a rom that controls the sound subsystem. I encourage you try reseating all the roms first.

since you have another board that's pretty much junk, you could even just do a full rom swap. see if it helps.
 
Yep thats pretty much the first thing I tried with exactly the same result...just need someone who knows which IC its is referencing regarding DCS2 0BAD as it does pass the sound checks on the initial diagnostic screen before it begins loading Carnevil. Have also tried diff HDD etc , think it is def a case of a bad IC, trick is knowing which one.

May do a logic comparison on the boards whilst running see if can find an obvious bad IC or component. Just hoping someone has cured this one before and could provide a shortcut.
