So I have this LG TV that started flashing. Thinking the symptoms were consistent with backlight issues, I replaced them. But the problem persisted. The flashing is a little odd in that the LEDs are not very bright when flashing. So I put my voltmeter on the LED socket on the power supply board and the voltage cycles between 30 and 90 volts (backlight plug not plugged in). I am assuming the voltage cycling is not normal, right? When I disconnect the cable to the mainboard, the LED socket reads 0V. Any idea if this is a power supply board issue? Or is it the mainboard? How can I check? What component might be bad?
Any suggestions would be much appreciated. Thanks!
