Mike,
     
     Sounds like the code doesn't implement a full initialisation, and 
     instead relies on the LCD POR. See the data sheets for HD44780 or 
     clone chips,
     
     or see

     for initialisation codes

Hi,
     
I am using a 16x1 lcd display with a 16C71. The C71 has a maxim 
reset circuit (I think it is a 705, but can't remember exactly).
     
If the power to the circuit is removed and then returned quickly, 
the display stops working. I guess this is because the 705 resets 
the PIC, but the supply doesn't go low enough to properly reset 
the LCD.
     
Is there a way round this?
     
Thanks for your help,
