[QUOTE="MacDude121, post: 1533485, member: 173432"] Hey guys, I'm having a very irritating issue with my MacBook. (Model A1181) For some strange reason, the backlight in my MacBook seems to turn off randomly. I know it's the backlight because if I take a flashlight to the screen, I can still see all of my icons and desktop. If I keep my screen set to the absolute lowest brightness setting, it seems to last for quite a while (it's been an hour and it hasn't turned off yet) but on higher brightness settings it lasts anywhere from 10 minutes to 5 seconds (depending on how bright you make the display) before it turns off again. I thought maybe a loose connection is at fault, but I've tried moving/banging/shaking the MacBook and nothing happens, so I doubt that's the case. I have also reset the SMC and PRAM, no change. Now I think it may be the inverter that is giving me the trouble, but I've come across another thread that shows other people replaced the inverter, screen, etc and this exact same problem persisted, making me wary that it may be the logic board that's going. That thread can be seen here: [url]https://discussions.apple.com/thread/2524176?start=0&tstart=0[/url] Any ideas? I'm not in the market for a brand new laptop, nor am I going to put a new logic board in this thing. I might just have to squint and use it on minimum brightness. [/QUOTE]
