Mayer, I beg to differ. I have one now in my shop with this problem. Logic board is working fine, external video is working fine, but backlight is NOT working on an set (LCD, inverter, and cables) verified working on another A1181. The problem *IS* on the logic board in this case. The logic board is to be repaired or replaced. Unfortunately, I don't see another way around it. I admit this is only the second time I've seen this, so it is rare, but I can confirm it *IS* a real problem. So is there a trick to repair of the logic board in this case?

Mayer, with all due respect, I beg to differ. I have one now in my shop with this problem. Logic board is working fine, external video is working fine, but backlight is NOT working. I swapped the logic board for a known good A1181 board (therefore re-using the old LCD, cables, etc.). In my case, the problem *IS* on the logic board. The logic board is to be repaired or replaced. Unfortunately, I don't see another way around it. I admit this is only the second time I've seen this, so it is rare, but I can confirm it *IS* a real problem.

I'm putting this here in case someone, like me, already exhausted all other t-shooting. Fortunately, I have 2 A1181's and was able to install a working logic board to confirm that all cables and accessories are all working. The A1181 with suspected bad logic board seems to have a problem. Even wiggling the "backlight" cable going to the upper-left socket on the logic board also did nothing. Again, swapping in a confirmed good logic board into this machine solves the issue, but I'd like to find a cheaper solution if anyone knows of one.
