Doesn't start. main fuse open. | Short at the output of the rectifier bridge, causing the fuse to blow. | Shorted diode d603 (byv29fx) next to the primary power supply capacitor, and check the two smd fets that are underneath it. one of them (13nm60n) was shorted. I also recommend measuring the primary power supply capacitors as I found one altered. replace everything and carry out preventive repairs. | PIXEL ASSIST |
