Hi, I've been searching the net looking for the exact same answers but to no avail. I'm working on the same model and can't locate the problem, which links back to the board. Here in New Zealand you have to buy a new board, there's no-one repairing them here and there's no information around either. They're way overpriced - what a monopoly! The board was pretty dusty so I cleaned it with pure alcohol and mostly the only thing which goes wrong with the board anyway is the power supply, which can be found in the Diode circuits but even then if that is the problem there's no parts available. Just wondering if you came across a wire diagram since you left this question last year and did you manage to fix yours? Evan
