Re: Faulty voice on a EII+HD, need help

2009-07-21 by synth.junkie

Sorry about the extra posts, I was having difficulties with my pc and didn't think they went through.
Anyway, I have reseated all the IC's on the output board.
I even went as far as swapping over all the IC's for voice 1 on the output board except for the D/A Converter and 1 of the logic IC.
Can the digital board on the right side cause this problem, i will probably try to re-seat those ic's also.
Regards
Rob
