This model is a bugger to disassemble. Remove front & rear panels and then remove main board.
Slide out ac board from main board, then you can slide main board off of transformer pins.
Resoldered between 175 and 200 cracked connections.
Reassembled and unit was repaired. Al outputs, drivers and transistors has cracks around pads, as well the connector where the transformer pins slide into, had no solder left on the connections at all.
