It doesn't turn on, it doesn't light anything. | Defective primary. | Identified several burned components. ((q1 - mdf13n50), (f1 - 6.3 a), resistors r13a, r14a, r14, r15, r16, all (0r68 - 2w) and 2 smd resistors on the solder side, r18 and r19 of 4r7, after changing everything, the power supply turned on, but the lamps kept blinking and the pfc voltage was low (160v), when checking it was identified r 21 of 470r open., after the replace everything worked..... a lot of work to find, phew... . | |
