My powerbook is 4 years old (out of warranty) and recently when it is moved, often the screen goes blank. The machine is still running, but I have to restart to get the screen up again. When I don't travel with the machine, it's fine, but when I move it, it gets glitchy. Any suggestions? It happened months ago and Apple ran me through diagnostics and had me remove some software. It didn't reoccur for months, but also I didn't take it anywhere. It certainly seems like hardware, not software. Thanks much.
Maybe turn on the PowerBook and plug the laptop into a TV or Projector and when it come up on the other screen, move it around a bit, when the screen goes white, if the other screen is still on then you know it's the connections between the motherboard and screen. Also try pushing the hinge in a litte bit and see whether the screen works when it's say half-open.
It could well be the ribbon cable between the screen and motherboard is knackered. Depends how brave you are at dismanteling computers, if you search on powerbook parts you may be able to find a company that scraps computers who could sell you the cable if it is a separate item otherwise it will be an expensive Apple repair!

Well the issue isn't with the graphic card. It actually is the screen of the PB (PowerBook). I had somewhat of the same issue about 6 months ago on my 17" PB G4. But when it started to do that with mine, the screen would also make sharp vertical lines when opening and/or adjusting angle. So before my Apple Care warranty expired I had the screen fixed FREE. So, if you do have your Apple Care warranty still and not expired, I'd suggest to you to find a Apple Certified computer shop or the nearest Apple store and drop it off with the explanation to have the screen replaced. Otherwise you will have to pay a pretty penny.
And if you do not have the warranty then i suggest you not to take it to a Apple store due to the extreme cost of a new screen on an old machine. Instead goto ifixit.com. This site is great for anyone who has anything portable from Apple (including the non-portable MAC-mini) for replacement or upgrade parts, cheaper and also helps with the install (DIY instructions and pictures to go with it)
Sure, the warranty on that machine was up over 10 yrs ago. Those laptop had a going life of 7-8 years, the internal hard drive that shipped with it, 4 at the most. It's called wear and tear and parts being outdated. So it comes down to how much your time is worth, what is it you choose to gain and the law of diminishing returns.
Did you run the cart initialization? Try this: (use new carts because it consumes some ink) press menue then start mono (blue) then fourtimes arrow up button (tel-index). machine will be in maintenance mode and lights will flash. press 7 then 6 then 4 then start mono. machine will refill tubes and ph with freh ink and do some cleaning. Leave maintenace by pressing 9 then 9. Do run a quality test print by pressing ink etc. Iy you cant see the letters and colored blocks well the ph has to be replaced. I guess your machine is a 2.5 years old. Unfurtunately brother ph didnt last longer than that time when useing generic ink.
