Generally when troubleshooting these types of power supplies, Check the bias
resistors for these driver devices, and also check to see if there are any
caps that are off value, low in ESR, and especially if shorted. Also look
for any opened series resistors on the incoming side of the supply, or any
opened fuses. There may also be some fuse resistors.
