Display backlight failures and PMU check fails
Hello. My iBook has had a bad backlight for a long time. Recently I investigated the problem, and temporarily fixed it. Then all insanity broke lose. The display backlight basically does not work at all, and now the computer fails the PMU check. This all happened days later after it was sitting on my desk .It does boot however if I pull the monitor up in weird positions. My suspicion is something is shorted, maybe the display inverter.
As as one large detail, on startup it also beeps loudly for a few seconds. Also it no longer charges the battery, and said battery no longer displays charge.
thanks for any help!
