It is good that there is no solder mask and appears to be a single layer (or double layer) PCB. Should be an easy fix.

@phooky one of the Psion units has a broken display cable - the tooling hole in the flex PCB was too close to the traces and since it is constantly flexing it breaks the copper layer.

@th @phooky do you have experience with the replacement cables? I heard that they're sturdier than the OEM ones and I've been meaning to buy one or two for the future

@th :( I feel like there should be a service where you mail OSHPark a flex cable, they toss it on a scanner, clean up the artwork, and mail you a replacement

@phooky oh noes indeed. I think i put the wrong bias voltage at the wrong time, and now the screen with the good cable is borked.

@phooky I should have paid more attention to `Note 1` in the datasheet, even though it was for the wrong panel.

@th double noes!!! I'm curious how the LCD itself could be damaged, though; is there silicon on there that's fried? I was under the impression that the panels themselves were pretty bulletproof.

@phooky I'm not sure -- anything outside of normal TTL signals confuses and scares me. However, I get another chance thanks to a (temporary) repair job on the bad FPC.

@phooky I'm going to try to power it up again with an external PSU, although I think the LT1617 is the right way to go for a PCB design.
