Hey all. I just bought a used Macbook pro 13, 2009 model with a bad backlight. I've read about inverter board, inverter cable and logic board issues but I'm not sure what to look at in my specific case. There are two things that it does: If I turn the computer on - The backlight will flicker once and then go out. The computer boots normally otherwise and if I shine a light on the display I can use it just fine. If I do the SMC reset and then turn it on - The backlight will work just fine until I get to the login screen. The backlight will flicker immediately before going to the login screen and then is off. If I hard reset (hold down power switch) and then turn it back on - The backlight works fine. I'll get the Apple logo and the little status bar below it but as soon as it goes to the login screen the backlight goes out. If I were a betting man I'd assume it's a driver or software fault but I'm stumped. I know my backlight actually works. I think I can rule that out. So what's left? Any help is obviously appreciated. I'd love to get this working. I bought myself a new i7 13" and my wife is so jealous that I got this used one for her. Just got to get it working... Edit: I have done the PRAM reset as well. No difference.
