I can only assume that there must be a piece of award lodged somewhere or the display and raduino. needs to be removed and? a very thorough examination made of all connections and pcb.Something is clearly drawing excess current and there is a remote possibility
that the raduino has failed.Hope you manage to locate the problem
Happened after drilled hole on casing with board installed, use compressed air to blow off any metal dust.
Close inspection did not see any. No smoke or smell after turned on.
Stuck at LSB A:7.149.950, cange change frequency.
Encoder changed, same problem, revert back to stock.
