Hey guys. I have a nitro ground shaker and in the middle of it being on it just shut off, just leaving the gi lights on, I pulled be back glass and turned it back on and no flashes at all ok the LED on the mpu, so I went over to the power supply board? first thibg I checked was continuity on all the fuses and they all checked good, so then I checked power at the locations at the top.

Voltages I got where 42.2 then 0 then 10.2 then 227 then and finally 5.7

So obviously I have dead line, not sure where to go from here, visually the board looks good, fuses look good, Any experts out there help me out?
