Help identifying display

Hey everyone. I've got a PowerBook I'm trying to restore. The screen flickers on, but no backlight and/or image I can see. I'm fairly sure it's the actual display but don't know what screen I need to replace it. Any info is greatly appreciated, and if someone has one lying around, I'd be happy to work out a deal.

Looks like a Powerbook 145 unit or similar. 

Capacitors are prone to failure on those units. 

When they fail the screen has a blue hue with no picture.

This display, SHARP LM64P51 has been used for the PowerBook 140 and some 145. You can replace it by the same or by the second model for 145/145B (SHARP LM64P58), but it is paired with the inverter board (find the pair, display + inverter). The CCFL backlight lamp is easy to replace.

There is a third model that goes in these PowerBook (140/145/145B): HITACHI LMG5200XTFC (to find with the cables and the inverter)...

I agree with bibilit, he problem with them is about capacitors failure.  I had several down (bad picture or no picture, just the backlight that displays a blue halo).
After changing the capacitors (on the inverter board too), they work very well.

Done by bibilit, thanks to him ;-)

The two SHARP display are very similar, like your picture, but the ref is different.

HITACHI model (with cables and inverter board) :
