Calling wpc sound gurus..I have a cftbl sound board [was from a gilligan originally] that will not bong. The sound/voices all work in test.
Also tried it in a gilligan [ironically with a dr who sound board in it with gilligan roms] with its roms and same thing. No 'all good start up bong' but sound still works normally.
Which eliminates speakers,cables,roms. Cpu ic was swapped and 6264 swapped for known good examples. to no avail.
Anyone seen this? Know how to get my bong back?
Has good clock signals, power and reset but no bong. Also some of the address lines and data lines read different than a known good sound board in game over state.
But yet it works....so odd. I also checked the 74ls374chips with a dmm and they test good. Dmm's can lie though so...
Just curious if anyone has had or repaired this issue before.
