Could be bridge rectifier
You must start by checking the panel supply voltages, if you look on the panel inside the unit you should see a label with a lot of voltages on it, such as V-set, V-scan, Va, Ve, there are test points on the power supply board and DC _DC board, that has the test points and the small adjustors for those voltages, check and see if they are correct or not, then start unplugging the cables connected to the other boards and check all the voltages again, those supply boards have a latch on circuit that will cause it to shut down, if you have back lights though, it could be only a board swap, most of the time it's a logic board or main board or a Y-main board, but you poweer supply could still be defective, good luck
