I recently put together a gra and afch nixie tube clock kit and everything works fine except that whenever the 1st digit in the groups of 2 tubes is a 5 every digit in those 2 tubes lights up. I figured there was a short in the HV5122PJ chip but I resoldered it and I am still having the issue.

Hello,

It looks like leakage of currents, as more numbers in the same nixie are activated.
It can be there is a problem with the nixie driver.

IMHO I would actually suspect a logic error, or code got corrupted during transport in the MCU, before I'd think hardware, based on what you've shown/described. Can the clock be reflashed remotely?

I believe it can be reflashed. I’ll look into trying that.
