What is the part number for the power supply?
Did you check for shorts on the transistor?

A27UAMPW-001 is the board #, which transistors do I check and can they be checked in the board.

start by checking the bridge rectifier then the other transistors on the the heat sinks etc also theres a few diodes on the primary side too check you can check these on the board if any test odd remove them and retest them.
