Hope this helps some one
It is most likely that there was some other issue rather than both LCDs being bad.
QuoteIt is most likely that there was some other issue rather than both LCDs being bad.There definitely seems to be an issue as this scenario has shown up more than once lately. My guess, based on very limited information, is that the LiquidCrystal library may not be working reliably with LCD modules that are slower (lower internal clock frequency) than normal. The 8-bit mode seems more tolerant than the 4-bit mode which doesn't surprise me. Perhaps a bunch of these marginal or out-of-spec devices just got dumped on the market.Don
But to get it working i had to use 8 Bit mode.
