well, we have some progress... I can now confirm that the cable works! However, my portrait display now doesn't...
I thought I'd have another go at seeing what I can adjust inside the case, so removed the case and top shield and hooked the monitor up to my 9600. On booting the computer, the display was garbled as upthread. There's a bunch of adjustable components dotted around so I got a long screwdriver and started adjusting to see what'd happen! None made any difference until I hit this one (circled and arrowed):
And when I say "hit" I mean hit! As soon as I made contact with the component, the screen snapped into perfect, crisp resolution. I marvelled over it for a minute or two before shutting everything down, putting the case back on and hooking up again. Upon booting now... garbled mess again. Ho hum. I took everything apart again, hooked back up, booted and had a proper adjust of that component. A couple of times I got what looked like a magnified portion of the desktop, but even that wouldn't stay. And then the screen went black, exactly as it looks when there's no signal going to it (computer off or no cable hooked up). Hmmm, I thought, let's have another adjust. And then this happened to that component:
Whoops!
So, can anybody tell me whether I've killed this off for good? What might have been the fault? Seems very strange that it was great as soon as I put the slightest pressure on the component, I'm thnking must be a poor solder joint, although that all looks fine to my (untrained) eye...
What should I do?
