THIS is why I always tell people to buy AppleCare on the portables... Anyway, the problem is most likely the LCD itself. The easiest way to tell is to connect an external display and turn on mirroring; if the problem only shows up on the internal display, it's a cable or the LCD panel; unfortunately for you, the cables are part of the LCD panel. The inverter pretty much never fails, and it's only related to the backlight anyway. More often when the backlight goes out, it's also an LCD panel problem. However, I have some good news for you. There seems to be a lot of confusion by MANY people about Apple's repair pricing, and I don't know where the misinformation is coming from. Their laptop repairs are all flat-rate, UNLESS the problem is caused by abuse or something similar (most commonly, dropping the computer). So, in your case, you're covered under flat-rate repair, not tiered repair. Flat-rate will probably run you around $380, not too much more than AppleCare, so hopefully you won't have any other problems with your computer. ;- Kynan Shook kshook at mac.com http://homepage.mac.com/kshook/index.html) John Pariseau <simplymail at ururk.com> writes: > I chose (why oh why, it was only 300 dollars) not to buy AppleCare. > Don't ask me why, I should have bought it when I had the chance. > > Anyways, how do I pinpoint where the problem is - the LCD, the > inverter, or the motherboard (please tell me the inverter is NOT part > of the motherboard)?
