The problem is this. When powered on , I simply get one row of blocks on the 1st lines of the LCD very very dim.

Any ideas? I've tried both RS232 9600 and also tried TTL settings on my Basic Stamp which I wasn't able to do any commands at all.

Any ideas?
Are there any way for resetting memory ...

I know difference between Rs232 and TTL.

I check with my other display and everything is ok.

Nothing can be display on the other one.

I think is sick ??? or the Eprom is erase ??? or ???
