Diagnosis needed: PowerBook screen dead but DVI works

If DVI out to external monitor works, does this mean that the GPU works?

When I run the hardware test I get a Video RAM error, 2DIS/16/2, googling that is inconclusive.

The LCD panel is new and verified to be functional, so that's not the problem.

Could a faulty video cable or something else that is cheap to replace cause a Video RAM error? Or is it in need of a new logic board? (It will not get one!)

Thanks,

The LCD screen has been replaced, the old one was cracked.
