Picture but no backlight
I recently bought a tv which had no backlight for 20 euros. I changed the backlights and the backlight inverter (which i thought they’re not in lcd led tv’s) but still the backlight doesn’t come on.
If i look at the voltages that go to the inverter board they are okay. But the inverter board gives for under a second a 94v to the backlight(to short to turn them on) and then goes to 0v.
If I understand correctly, does this mean the mainboard is not telling the inverter to come on? And if so is this fixable by resoldering a resistor or chip to get it working?
The exact model is: 40PFL3208H/12.
Esta é uma boa pergunta?
