II replaces the remaining ICs and its working! Woohoo!

Reflowed the ttasnsistors on the top side and now I am back to 12 LEDs on. I'm assuming the LEDs shouldn't be on, but otherwise that feels like an improvement as it means I get mattias switch events for 12 of 16. I'm also getting events for depresses on the right 4 encoders although they seem a bit random in the actual event details. I've also replaced IC2, IC3 and T3 based on advice from ChatGPT but that made no difference.

Thanks, perhaps I'll shoot over to the UK ;-) I've rebuilt the core board now and I'm back where roughly where I started. At least I feel confident I have eliminated the core as a possible cause; the problem must be with my LeMec board. Done some more reflowing on that board and now: - just 4 LEDs light up on power up now - all encoders generate counts when rotated but not depresses - botton left 4 buttons generate no events; bottom right four are working - mattias switches generate events for the four that have illuminated LEDs but not the rest
