Dookie I think the best way to troubleshoot this problem is to remove the display and test all segments one by one using a power supply and eventually a series resistor . Google the partnumber of the display for connections . I once had a similar display with a kind of "leakage fail"( segments lit while not powered ) . The led problem might be a processor issue (multiplexing problem) Hope this helps , happy 2021 !Bob ( retired avionics repair tech )

BG223217432 The variable resistor is to adjust how fast the blue LEDs on the base "breathe." I have not found a schematic; however, everything is self-evident with the exception that you need to solder M3X10 screws to act as a guide for the springs. It's too bad they didn't program some Christmas music instead of Fur Elise.

Q: Where are the programming instructions? Which resistors are 1K and which are 10K?

warmbell Hi, I think I can help with the LDR and the NTC. I ordered with a case and it has an oval cutout for the the LDR nearest to the switches so that would make the LDR has to go in position RT2 tnd the NTC in position RT1 which has a small round hole in the case. Has anybody found out the instructions for the switches yet? Gerald
