    Thank you Duke, a gentle flux and heat of LP8550 (U7701) did the trick

    Very likely that it is just a bad LP8550 or corrosion around it.

    Had a WLED cause this on an air recently.

    I'm trying to find out if there is a problem with the actual backlight or the circuit.

    I'm getting around 24v on PPHV_S0SW_LCDBKLT until the brightness is turned up, then it jumps all over.
    I don't have another assembly for this model in stock to simply try another.

    What do you recon the odds are that its the actual backlight in the screen thats the issue?
