Power Macintosh 4400/200 (7220) – No video output
Hi guys
In my collection, I've got a "mutant mac", a Power Macintosh 4400/200 and I'd like to bring it back to life again!
The owner wanted to throw it away, so I got it (with mouse and keyboard) and the same day, I also saved a boxed Power Mac G4 AGP 350 Mhz from being recycled...
Well, the problem: No video output at all! As I don't have any old Apple CRTs (yet ;–) ), I tried 5 other CRTs with a DB-15 to VGA adapter (tried all possible resolutions). The CRTs lights don't even get green when I connect it to the 4400.
But I think that it still boots (start up gong, hard drive seems to be working). I've done PRAM-reset several times...
So:
1. Adapter dead?
2. VRAM dead?
3. PRAM battery dead? But that wouldn't affect the graphics, I guess...
Where would you start?
Thx a lot!
