I would like to see a CRO on the D/C pin during GUI RESET LCDPANEL
A CRO, not the logic analizer and with the LCD attached. CRO lead on the LCD end.
Compare the good board with the new board.
You said you could see data going both ways so my guess is it is either stuck in data or stuck in control mode.

PS If it makes you feel better, I spent a week trying to RF proof my rain gauge. It is near a high power transmitter.
After a wasted week I realised it was playing up when the backup power supply was turning off (normally solar but a cloudy few days) and the AC extension lead was too close to the weather station pico.
Move the cord and problem fixed. Not The transmitter after all.
Simple once you find it.
