Q: Blue lines all across the display and external monitor (not mirrored)
Hi
I have a Powerbook G4 15" running OSX 10.4.11. For the last 6 months my mac monitor has displayed blue lines running right across the screen, making it unbearable to use. I connect the mac to an external monitor and expected the blue lines not to come up on the external monitor but they do. I've not got "mirrored" on so I'm wondering how to fix this? I thought it was just my monitor that was stuffing up, but is this something to do with a video/graphics card and so all displays will have the blue lines? Please help as I'd still like to use this mac to run but the display is terrible and kind of useless. If anyone does know the problem and that it would require some professional fixing, how much roughly would it cost?
Thank you very much for any help.
PowerBook, Mac OS X (10.4.11)
