Powerbook G4 - Scrambled Screen

[Innes]

Hi All

Anyone able to diagnose whats up with the example linked below? I'm not interesting in buying (although it is a relatively blemish free case which is uncommon)

I guess im just curious, the image its outputting is bizarre

Failing Graphics chip perhaps?

Cheers!

Yeah that looks like a failing graphics chip, The 2011 MBP's can come up with similar patterns when the chips go in those

I wouldn't be surprised if an OS reinstall fixed that, there's always the possibility that a few bits were flipped on the graphics card driver and that's what resulted.

Considering it happens during the Boot screen which is strictly the OpenFirmware frame buffer it looks like indeed something is up with the Graphics chip or related circuitry

Flaky cabling? Bad timing/sync? It looks like it's drawing the screen but duplicating bits of it.

Maybe the video cable. Sucks because it looks mint oitherwise.
