hi, i have 2 MacBooks here. one has a backlight problem - if i set the backlight to 100% - it switches off. the inverter is ok (already changed it before i found out that the light only fails when it’s to bright) the other one is dead, does not respond to anything - the logic board looks fine, nothing special, no fluid damage or anything else - any suggestion ??
Since the powers goes -> logic board-> inverter cable -> inverter board -> backlight lamp I can’t see another culprit than the logic board if you replaced the inverter cable and the inverter board. I don’t think the backlight lamp could be causing the problem. Could you install the display coming from the deat unit to the problematic unit if they’re compatible and check if the problem persists ?
