This TV had multiple problems that I've encountered one after another.
When I first got the TV it had standby light, turned on and off with the power button but no backlight and no picture.
I opened it up and found a transistor Q1 on the main board that was obliterated (see picture)
I purchased a used main board from ebay and installed it, same symptom as before so I checked voltages on the PSU, all voltages were present and correct.
I opened up the panel and found a burnt to a crisp LED so I removed that cleaned up the pads and took an LED from a Vizio LED strip put it back in the tv and powered it up.
Backlights came on and blinded me so I re-assembled everything and powered it up.
No the picture is upside down with solariztion.
What would be the cause of this? Main board? T-Con?
