I fixed the code, but it won't help, just after re-connecting 5V power pin,- LCD started to behave as normal. Hence power pin re-connect works as "factory reset" button for LCD. Cool ! You saved my life :-) | |

Anyway, I fixed the 20,4 to 16,2 just to be sure and if it starts acting up again I'll have a close look at the backpack. | |
