sorry, when i tested the LE80 chip, i didnt receive 8volts, just millivolts at all pins..
so as i was testing voltages on the 5 pin chip, i accidentally touched 2 of the pins at the same time, and popped a hole in the mosfet opposite to it (the 3 pin one) as you can see in the image.
But i think you may be onto something, with that 8 pin chip as i wasnt receiving 8v from that either....
I think these guys in the link below have worked out what the problem is with these screens and exchanging them, as they are charging $716 for an exchange screen. so i assume that they fix your old one, and give you another repaired one they have fixed previously.
