For two weeks i have been working on repairing the WMS UNI-750-1 power supplies for the bluebird 2. There seems to be more to just replacing the exploded transistors and U206 and U205. Need help :99-

The symptoms of the power supplies that have the exploded Q5 and U206 on control board, these are the components that will need to be replaced. the major problem is, all the power supplies blow different but this is a start.
Main Board: U1, D5, D17, D18, D20, D21, Q5, R4, R2, R123
Control Board: U204, U205, U206, Q2, Q4, Q5, D3, D4, D5, R41, R85, R86, R87, R88, R89, R113, R114
Worst power supply to work on. It takes about 3 to 4 hours to work on one. Good Luck
