Picked up a WCS with no 50V. What i have done to date:
Tested (twice) fuse F112 out of circuit
Checked J102 - this is strange (but hopefully gives a hint as to the problem?) - when it is unplugged, there is 13VAC across the black/yellow wires, however when i plug this into the power driver board, it drops to 0.5VAC. This occurs, even when only J101, J102 and J104 are plugged into the board
Pulled out power driver board - it looks quite clean - replaced BR3 and C8, which as far as i can see are the only components in the 50V circuit, and still presents the same symptoms
I'm a bit stumped as to what to do now, any ideas?
