The display that I"m finding on eBay has the model number:  PVI PA050XS1 (LF).  Does the "LF" designation indicate that its not compatible with the Origin?

Thanks

Many of the displays in this family has the "(LF)" prefix. I've not been able to find out what its meaning is, but I son't think it's anything to worry about compatibility wise.

There's a nice overview of the variants of this LCD module panelook.com. You can get versions with LED backlight which should work, but you'd have to arrange the LED power of 11V (not available in the Origin, but could be added using a DC-DC converter).

BTW, you can get these for as little as around $16 here.

Cool.  I just ordered the PA050XS1 LF.  Considered going with the PA050XSJ, but decided to play it safe instead.  Also ordered a new Microsemi inverter and new pots.  I'll let the forum know how this all turns out.

Ug!  I ripped the ribbon cable on my new display module!  Not sure how that happened.  Treat these ribbon cables like paper!   :-[

Ouch! IME that type of cable is reasonably durable and doesn't rip like that from normal handling (still treat them carefully, of course). It looks like the rip is where it meets the housing - could it have been damaged by a kink or crack in manufacture/packing/transport? Might be worth asking for a replacement.
