Hi - I have a 20" aluminium cinema screen, and the pins on the DC plug (the one that goes in to the PSU) have become damaged in transit. I attempted to bend them back into shape as best I could but I am getting no power from the screen.
I found out that Apple don't actually repair this - they simply provide a replacement screen at something like 80% of the cost of a new unit. For one broken plug. And I can't get hold of a spare plug to even attempt to resolder myself (typically this is an Apple proprietary item).
So the only solution I can see would be to put a new male/female on the plug/PSU socket. Or wire directly into the PSU. But of course it doesn't look easy getting into the case of the PSU - no screws on it. So if anyone has any ideas, I'm all ears! Otherwise I now have a very expensive aluminium paperweight.....
