I have had my dell inspiron for 5 years now. two years ago, I dropped it and the LCD shattered. I purchased a new LCD from Amazon and took it to a PC repair store nearby. (Fry's Electronics was the first choice but couldn't install the LCD due to liability issues.) I got my computer back and it worked perfectly. Now fast forward a month later and i haven't used it in about 2 weeks. I go to start up and the screen is black, I check the brightness and that didn't seem to be the problem, then i see that the LCD is fine but the backlight is very dim and keeps flickering like a light about to burn out. Could this problem be hardware and a part stopped functioning?(motherboard/inverter I hear are common culprits) Or could this be a software issue?
