Damaged 16x2 HD44780?

Hello, I have tried connect ENABLE pin of HD44780 display direct to Vcc. It seems the display is not working since that. It possible I have damaged it?

Thank you.

It seems the display is not working since that. It possible I have damaged it?

It is possible but why not do some troubleshooting to find out?

Was the display working properly before you connected E to VCC?

What do you see now? Nothing, garbled text, a row of blocks …

I have seen garbled text befor I reset it. I seen nothing now.

I suggest that you remove all of the wires and start over. Follow the tutorial at http://www.ladyada.net/learn/lcd/charlcd.html. If you cannot get the row of blocks on the photograph just before the section called 'Bus Wiring' then your display is probably bad.

No blocks are displayed. I have made an order for a new one already. Thank you Don.
