a dying iBook display?

Hold on a sec! It could just be a dirty or faulty connection with the screen- I had this once on an old Sony PC laptop- It was too much hassle to fix it so I just learned to live with it, but if you wiggled the screen around it would come back fine and last until you jogged it again. It worked like this for months before it properly died and wouldn't come back on again. How long has yours been like this? have you tried wiggling? (incidentally the first rule of engineering, just above kicking)

Sounds like a inverter cable problem, it could be the inverter, but from past experience if the inverter has a fault, it simply wont power the bulb(s) at all.
Either the inverter or the cable would cost around £100 to replace at an AASP.

I can get what replaced? The cable or the hinge? My auto-sleep hinge switch hasn't worked for years.Hector said:
The problem has gone away for the moment. Earlier, it was sometimes responsive to moving the iBook, but also to clicking the scrollbar. (Apparently from pressure on the trackpad.) Now, using it on a desk, it seems to be more stable than when I was using it on my lap earlier.
It started after I got a memory upgrade Friday, so I don't know if it makes sense to consider that may be part of the problem. Is the backlight power cable anywhere near the memory slots?
the sleep thing is caused by a magnet just under your keyboard on the right side which triggers a switch in the lcd, the magnet could have moved or the cable could be damaged, take it to an apple store to have it check out, i just replaced my whole bezel which replaced all the cableing.
DavidCar said:
Not the hinge just the cable.
One end of the cable plugs into the logic board just by the ram slot.
The fact that the sleep function in the lid (the reed switch) isn't working suggests more that it is the cable as the inverter and reed switch cable are one.

I have some display cables I could unload cheap (I'm not home right now and don't remember exactly what ones). I replaced the metal bezel and hinge on G4 iBook with a G3 display and have most of the G3 wires. PM me if you are interested in replacing some cables yourself. I will warn you it's not the easiest job. It's not all to hard, but if you are not comfortable working on computers I would not recommend it.
Thanks for the offer, but I don't want to try that approach.DaveP said:
It is sounding more like the cable is the problem, and I appreciate the advice. It seems to work fine as long as I use the iBook on a table, but this morning the brightness decreased 50% for several minutes, then even briefly blacked out when I was using it on my lap. I'll take it back to where I had the memory installed to have them double check the cable connection.alexprice said:
When we tried to reproduce the display problem at my Apple Authorized Reseller, the most predicable way to make the display flicker was to push on the case to the left of the trackpad, or in various places in that area. I understand there is another display cable in that area, and I could have them work on it for a while to try to reseat the cable. It is still usable most of the time, presently it is dimmed a bit, and it can also be used with an external display. I don't want to put a lot of money into it while I'm trying to justify getting a new computer.
