Hi and thanks for your email! There's hope!
I know some people are out there who feel our pain!
Good News! I found
ScreenTek their LCD's are inthe $500 range and I also found an Apple repair shop that will do the work for $100. (Without sending it to Apple-- sometimes NOT having AppleCare really helps!) So, I'll be able to fix my little guy pretty soon. If you'd like the same repair done, let me know- I'll be happy to give you the repair shop's phone and address.
If you have a M5884 Tibook, call and ask
ScreenTek for a display. Give them your model number, etc. and they will look it all up and cross reference it for you. When I called, they were out of stock on my screen, but had a shipment coming in later this week. The website doesn't list our model Ti Book--CALL FIRST!
Ask them about an LG Phillips LP152W02, W1 or W2 or an Unipac B152EW01. It seems that these two models are direct replacements for what we've got.
In the mean time... more good news. You can mirror your current set up. That's what I'm doing right now. In OSX, go to your System Pref, click Display, and select the Arrangement tab. Now drag that tab over itself or click "mirror displays" in the lower left hand corner of the window. If you're running 9, you can do the same thing through your "monitors" preference. You should be in like Flyn.

It's only a "get me by", but it'll do in a pinch.
