I think the locations of the external connectors are not the problem. New openings in the shell can be made and the old opening can be closed with 3d printed caps.

But from what I saw on eBay listings the lvds connector to the panel seem to have different pin amounts and different connectors.
Even if the pin amount is correct I'm not sure how well the connector can by adapted.

Often the other board are layout for eDP and LVDS 41 pin and 51 pin, but not all connectors are soldered onto the board. And often the boards have FFC or FPC connectors. I'm not sure what...

Hi,
I find the service manual for the 24GL600 quite helpful. The naming is not 100% correct but the voltages seem to match.

I swapped the IC401 and the 12 MHz quartz and getting the right voltages on that coils, but I get no high signal on the pin 2 of the LED driver IC.

Do you think it is possible to check the IC200 and reflash it?
Or is it alternatively possible to get a hole new board that just works with that panel?...
