I have the exact same problem with kit #152.
– LEDs not working
– rotor displays not working, except for the dots
Occasionally, when the board was off more than a few seconds and no power was left in the circuit, a very short flash from some LEDs on startup.
I have verified over TTS and the serial monitor that all buttons and rotors work fine. Also, the Plugboard does work.
There is one difference to the original post:
My kit was provided with a VK16k33 Chip instead of a HT16k33.
I think I will look for a new ht16k33 chip, or do you guys have found a fix or have an idea what I can try?
