    Well, if I understand it correctky its not needed if you use the default stuff, but I tried to add the whole define-block mention in the manual, and there is no difference.

    I also tried to put a LED on a pin and make it flash so I know that the pic is "running"..

    Try putting the xtal and the caps back on there anyways? Just in case the config fuses didn't take.
    Put an LED on an unused pin for grins and see if it blinks for ya... I ALWAYS use a heartbeat LED or two on all my projects. It takes sooo much guesswork out of the equation...

    Code:
    @ device INTRC_OSC_NOCLKOUT,MCLR_OFF,LVP_OFF,WDT_OFF,PROTECT_OFF
    DEFINE OSC 4	' Lets work at 4MHz
    CMCON = 7        ' Disable comparators
    pause 500          ' grace time for the LCD to initialize.
    led var portb.0
    main: led = 1 
            LCDOUT $FE, 1, "Hello world" ' Clear display and show text
    	pause 500		          ' Wait 1/2 sec
            led = 0
            LCDOUT $FE, 1, LED Off"
            pause 500
            goto main			   ' Go back

    Yes, I accidenticaly made it a pulldown first, but when it didnt work I checked all connections and fixed that.

    As I wrote I already did that ..I also like the idea with a heartbeat (Even if it doesnt look as nice at it does on my old HP PA-RISC machine if I have a spare pin.

    It flashes so the oscillator doesnt seem to be the problem.
