Inverter does not oscillate, in this case the voltage of the LEDs is only 12v and the normal one would be 35v | In my case, I solved it by simply inverting the two identical circuits on this board, as 1 of them did not activate the MOSFET, I inverted their position and the defect was remedied. | Alberi F S | |

Does not turn on, pfc circuit does not bend 400v. Vcc supply of cis u101 and u600 is low, causing the 400v not to double | Shorted components close to u501. | Replace of components: zd500 zenner 15v, smd transistor q501 "I took it from scrap from a similar PCI", cracked c509 smd. I didn't find the schematic for this power supply. | rafaelmoraes99 |

Turns off by itself, with loud noise in the audio, with OSD scanning. | Microprocessor defect. In most cases, this defect is resolved by changing the 10u x 16v capacitors. But if that doesn't work, change the microprocessor | Changing the micro u11, mt8222 or mt8221, check as tsound are two versions. | rafaelmoraes99 |
