Titanium Powerbook LCD problem

Not sure if this is the right place but here goes.  I have a Ti-Powerbook G4 with a 15" screen.  I've had it for a few years and after the first year the screen went black.  I could tell there is still an image on the screen just really faint.  So after some research I had determined it was either the LCD board or the backlight.  I found both on ebay and changed the board, no help.  So I proceded to change the backlight.  I had detailed instructions on how to do this along with a warning that said don't try this at home.  Well I did.  After tearing the whole thing apart and successfully changing the backlight, when I was putting it back together one wire was on the inside of the inner workings of the hinge and one on the outside.  There was no way around this so I proceded to put back together.  So when the hinge assembly was done I pinched one of the wires in the hinge.  Put it all back together and started it up.  The wire went ssssssss and now I'm back to a black screen. 

This is not a procedure that I want to do anytime soon since I am probably lucky it still works at all.  The Mac store wants to replace the whole screen for $800.  I've seen places like Apple-restore or powerbook-restore or something like that, that you send them the powerbook and they change out the screen for $300.  Does anyone know of a place that I could take it to just swap out the backlight for more reasonable $$?  In Oregon?  Thanks

Re: Titanium Powerbook LCD problem

If you shorted a backlight wire on the hinge, the inverter board (another inexpensive part that drives the backlight) might be bad now, too, but not the whole screen.  Can you still see a faint image when you hold the screen under a bright lamp?  If so, the screen's fine.  If you want to try it yourself again, this time putting the wire back the "right" way, there's some guides on ifixit.  Also, I don't know if this will help, but there's a lot of pictures of a disassembled powerbook.  If you'd rather pay someone else to do it, you might have better luck in Everyday Tech (accidentally called it balloon help).
