Hello friends of the forum ... I have an LG smartv which does not turn on, only the standby LED flashes (approximately 7 times) and goes out ... measured at source board voltages which are:
P-DIM1 = 0.57 v
DRV-ON = 0.10v
P-DIM2 = 0.59 v
PWR-ON = 3.43 v
13.2 V = 13.3 v

Generally some LEDs are shorted, as they are in series, the others receive excess voltage. To verify and change the LEDs, the panel (screen) must be opened very carefully. You have to take into account the voltage of the LEDs (6v. Or 3v.), Once changed you have to measure that the new and the original ones have the same voltage. A "Blester - led tv panel tester - Creatronica" is available online, with a single button you test a led or a series (the voltage is automatically adjusted). Regards
