Why my monitor is showing vertical lines and freezing after the boot?

Hi, hope someone can help me with this.

I was using my iBook G4 yesterday and suddenly it started showing vertical grayish lines. I restarted a couple times after that and one time it came back as it should (no vertical lines) for a couple minutes and then the vertical lines came back up.

I tried to restart it again, unplug it form the outlet, take the battery out and put it back in (just to make sure I tried almost everything) but nothing different happened.

I use an external monitor as well, but it shows the same problems that are showing on my ibook. Sometimes shows the vertical lines and sometimes it's just plain blue or black.

After that I rebooted the computer a few more times and noticed that I could see the mouse arrow (pixelated and with the vertical lines above it) and even move it around for a couple minutes, but after that the computer just froze. It didn't go to sleep nor reacted to any of the keyboard buttons/mouse pad interactions.

I was reading some of the questions here in the forum today, but i couldn't find anything more specifically related to my problem. Can anybody help me?

Thanks in advance. Eduardo.

p.s.: Some pics to illustrate my problem.

The GPU, video chip, on your mother board has a compromised BGA (ball grid array) or the chip itself has died, more than likely the BGA is the problem. If the BGA is the problem it usually can be repaired by reflowing it, instead of reballing it. I would recommend attempting the reflow yourself or replacing the motherboard. There are people on eBay charging $250.00 for such work on an Apple. The ifixit has your motherboard here. for about $279.95 + shipping. I haven't been able to find a decent guide for you that is done specifically on your board model. If this is something you may want to attempt please let us know and we will find a guide(s) for you.

+ I'm learning things today from you ;-) Do you have a link to show a picture of this problem


I have a Vizio flat screen tv and it had the exact same symptom. I reset it to the original configuration and it went back to normal.
