I have a issue with backlight as one quoted Backlight works for a split second, inverter or inverter cable?, GPU is fine, I can see the screen content from an angle.
Backlight stays off all the time and also when moving the lid up or down, but it flashes for a split second when changing the brightness upwards. This rules out the cable.
Anyone seen similar before, is it an inverter issue or the fluorescent bulb?
Is this a good question?
