If you have a problem with a laptop screen is there a definitive way of telling whether it is the inverter that has failed or the screen? I have seen a number of forums mention the possibility of either but no way of actually definitively telling.
I have a HP NX9105 where the display is extremely dim but is just visible in light and an inverter will cost a third of the price of a screen but I don't want to buy both if only one needs to be replaced. Have tried the Fn buttons and the screen button.
Any help greatfully appreciated.
