Thanks Mister_e,
Fuse config is now clear to me ;-)
Back to my display, I did what keithdoxley suggested but still it's not working.
Finally, I connected my usual display on the PIC with an 8 bit data-bus. It works fine so, for sure, the PIC is not the problem.
I have contacted ELECTRONIC ASSEMBLY and asked for more informations. I still can't believe I would have broken both displays...
For normal use, the display must be set in Read or Write (R/W)?
One last thing about the contrast control: would be the syntax to change the contrast's setting "LCDOUT $FE, $74"? According to the table (Initialise_LCD.bmp) in post #10, it should but how to change the amount of contrast???
