This TV has already changed the LED bars 2 times this and 3 times | So as not to burn the LED on the bars, I did this procedure, I changed the resistor r765=2r2 smd to 4r7 smd, the 160v voltage drops to 150v, and the voltage of the LED bars was 94v 220ma drops to 88v 1.6ma, the TV worked It worked and it didn't come back, but my client has been in my workshop for 7 months, everything is ok. | Defect resolved | Andrei |

Arrived at assistance completely dead. After visual inspection and with no apparent defect in the power supply, I verified that the fuse was open. In basic measurement of the diodes, I found the n-channel MOSFET, reference 13nm60n, 11a/600v, in the qp801cs position, shorted. | After changing the MOSFET and fuse, it worked normally again. | AnisioH | |
