I bought a Pioneer LD-660 that has perfect picture, but the audio sounds like it is underwater. It looks to me like it is going into the audio board like that, so I am thinking audio demodulator maybe - but I may be wrong. I need a schematic and/or a service manual. Does anyone have one I could get a copy of - preferably PDF. Or, better yet, if anyone knows how to fix this problem, I'd really appreciate it!
