Try changing out the Pico fuse. Only 50cents from online West Florida Components. Buy a few. Mine went out twice. It is Item # F021. It is a .5amp (500 mA)fuse-green and looks like a resistor. Location on the circuit board is near the transformer and on back edge or board behind the 2 brown wires connecting to the board and to the side of the 4 diodes there. I left the bad fuse in place and soldered the new fuse to it's legs-a lot easier and does not damage the PCB.
