Display has 23 vertical columns with blue ladders. Won't boot into OS. 10.4 or install disk but will get to first install screen so I can run disk utility to find specs and do clean-up.
I can run Disk Warrior successfully but display has vertical hash marks even on the Apple start-up logo.
Any ideas on fixing? Costs for parts?
Has 10.4.3 installed.
PowerMac 12.1
Это хороший вопрос?
