Hey Folks,
When I first picked up my Freddy, I unplugged either the 5 volts output or the 12volts unregulated off the power supply board. This caused a couple problems. 1 the sound went out, 2 the DMD controller died. I have since rebuilt the HV section on the DMD controller and replaced the U8 custom gal. I have DMD now. But I have no idea where to begin on the sound. I know that the 12 volts unregulated went into the PS and came back out to go to other things. And I think unplugging the 12 volts was what caused the problem. Either the lack of the 12 volts to somewhere else or lack of 5 volts to control something caused both boards to fail. Like I said, DMD controller is now working. The sound board's LED will sometimes come on and stay on. Other times it goes off and stays off. I can hear amplification in the circuit, and sometimes a high pitched whine or shriek like its trying to do something but can't. My question is does anyone have any advice for me, or has done something similar. I thought that it might just be blown ROMs, but I thought someone else might have a better idea. I think the auxiliary digital voice board may be good as one time, mine spoke some dialog(very creepy at the time). So I figure the sound board just isn't controlling anything. But it could have just been a freaky glitch. Any advice. Anywhere....Thanks in advance.
