Question about Apple iBook G3 Mac Notebook
I had a problem with the screen blank at switch on. i was told to get the graphics chip re flaoted, which i did via a local mac shop. but they refunded my money as the refloating did not seem to work. it worked a bit! the screen works for a wile but sooner or later it freezes or goes blank. i don't know which chip it is , i know it's near the hard drive. and how hard is it to reflaot as this seems my only coarse of atction. shit or bust as they say. i am an electrical technician and sparky trained person, so any help in locating the chip and adviceon coarse of action would be welcome.
There is no such thing as refloating the graphics chip on a mac laptop. The video card is intergrated onto the logicboard. You should first connect an external display to the machine to see if its the display or video card. Once youve eliminated that, you can rule out whether its the video card, or the internal hard drive. If its happening when you boot the machine, and it freezes or locks up, its most likely the hard drive or a faulty OS. If the problem happens intermittenly or when the display is pulled forward or pushed back, it may also possibly be a severed LVDS cable in the display or where it connects to the video controller on the logicboard.
Keep me posted,
Your certified Apple technician.

Apply about 2 pennies height under the GPU should take care the problem. Reason, the graphic chip becomes loose.

Sorry, Fire Sine, de troof is strange.
The ATI video chip on the iBook Dual USB (12" and 14") is soldered to the logic board using ball grid array (BGA) technology. For whatever reason, this particular soldering job was prone to failure on MANY, MANY iBooks. Apple had a free-repair program running for a time, but this has ended.
MaxyMouse, I'd be surprised if your local Mac shop had the gear to do the resoldering in-house. There have been lots of amateur-level fixes suggestion, all purported to "re-flow" the solder balls involved. Very dicey.
The only fix that -I- have faith in is done by First Phase Technologies. http://www.firstphasetech.com/ibook-repair-g3-g4.html The good news is that their approach is inexpensive, using professional-grade equipment. The bad news is that (a) they want your bare logic board, they do not do disassembly and reassembly, (b) their work is "best effort". I've had an iBook 800 processed by them, and it worked perfectly. In my mind, this is only worth doing if you have a 700+MHz G3, or a G4. Let me know if you want/need help with the teardown.

Open de laptop mac and use the blower.
Put it in the video chip for 5 minutes and quit this.
