Hi I have an old PowerbookG4 15" Aluminum 1.5 GHZ at start up, the screen has a rosy color instead of the usual grey then, when the is running the display show some horizontal lines when .

The pram battery is dead as well as the battery.

The logic board passed the hardware test as well as the Video RAM.

If I play a DVD it does not seem to act up.

Could it be just the PRAM battery which need to be changed?

Thanks for your answer

I hate to say it, but you might have a PB with a failing video chip. While I have the same PB with no issues, I have seen this before on my G3/800,900 and G4/550 TiBook.
While there were some DIY fixes with the G3's there is really no such luck with the AI's aside from a sysboard replacement.

I don't now what you financial situation looks like, but I would start looking for a suitable replacement as soon as you can.

It's the screen. Solder joints are failing on the back of the Powerbook's 15 inch screen. Afraid the screen may cost you more than the value of the powerbook. The A1095 is valued at about $70 and the screen itself will cost you some $100 new.[/url]
