Suddenly the screen of this PB 100 stopped working.

The PB 100 completes the boot either from the HD or the floppy, but on the LCD there is nothing, just the backlight ring works, while the contrast does not change anything.

Ideas?

Let me guess, it looks like the contrast is turned all the way up? Alll the pixels are black, perhaps? (a little hard to tell maybe but watch it as it boots up).

This is a common way for pb100's to die, in my experience. Something is loose somewhere perhaps, I've had this issue get "fixed" for a while by shipping them across-country via UPS :)

I've taken my display all the way apart and checked the values on the dial that adjusts the contrast while I turn it, they do change, I'm not sure what the original values are supposed to be.

If someone knows what component is failed, I have 2 pb100's that could come back to life. I like the pb100 a lot.
