Gentlemen, some developments...

OK, monitor arrived, but I had to source a cable. Managed to get one via a post I made to Usenet, for free too! It's an Apple cable, 13W3 to DB15, but the 13W3 end only has half the pins that seem standard, but the chap assured me that it is the correct cable for the portrait monitor I have. Here it is:



Now, I hooked it up to my LCIII to test the monitor and here's what I get:



What's the issue here? Can any of you guys diagnose this as fixable or terminal?

I've opened the case to see if there was anything I could adjust but I'm working blind here, no idea what I'm looking at...



Cheers!
