    LG 60PV450. Help to identify burned resistors.

    Can anybody help me
    I have the LG TV model 60PV450, there is no video, only audio, after checking the Y plate, I noticed that the resistors in the SMD surface of the bottom part are burned, also the FGPF4633 transistors.
    Could you help me identify the values of the resistances that are circulated in red that are shown in the attached photo?
    Thanks.

      Can you see any numbers on them ? If so what are they ?

          No, I can't see any number. Just the location number. R430, R439 and R517 I think the value is 10 ohm, but I'm not sure.

              What is the part number on the board? If it's EBR73561201, I have a bad one in my shop. I'm out of town until tomorrow night, but I can look when I get back if you haven't figured it out yet.

                  Well, I think it's the same, mine is EBR71516301, I would appreciate it if you could check if the resistances are 10 ohms. Thank you very much.

                      If those resistors are connected to the GATE of the FGPF transistors and to the output of the driver IC, then they will be around 10-33 ohm in value. The exact value is rarely extremely critical.

                      If they connect from GATE to the SOURCE, they will be around 10kohm in value.

                          All 3 are 10 ohm.
