Its when It is tapped/hit (not hard) in the back right corner of the laptop. Is this a GPU problem or is it something like the Backlight or the logic board? the backlight hasnt shown any pink or anything so I know its most likely not that. I need a response quick because i need to know how much this repair will cost so i need to know what it is that needs to be repaired so that the seller on ebay can give me some money back to pay for it. Thanks - Chris
is not videocard problem but backlite problem. i think it is an easy fix as it appears to be a loose connection.
actually depends on version of g4 if its a second gen its a flat connector that is soldered to the main board so no luck in replacement however if it is a first gen its most likely a loose connection but getting to it is not easy and not for the faint of heart.
