Hello,

Yesterday the backlight on my Dell XPS 1530 effectively died. The picture is still there (incredibly dim -- can't really make anything out) and the computer works just fine when hooked up to a monitor. I would guess that the CCFL tube died and would just buy a new one, but is there any way to sure it is the tube and not the inverter that is busted?

Thanks.

From what you describe, to me, it sounds like an inverter problem instead of backlight bulb.

I do not know of a way to easily test it without swapping in known working parts.

These videos have helped me in the past and may also help you:





Good luck :thumbup2:
