Hi Henrik,

Try adding a LED to an unused pin and blink it a few times at start-up. Just to verify that the PIC is still actually executing code.
Will do.

Are you using an extarnal crystal or are you running on the internal oscillator?
Internal oscillator.

It does seem strange that the PIC wrote the test lines to the LCD then stopped when the back-light was fired up. It would be nice if it were something not too serious.
