I have a 1g TiBook with a display problem that I believe stems from a broken hinge (I have the hinges on order and will replace). In the meantime when I move my screen it will flicker, unless it is just in the right spot, and will also go completely dark or freeze altogether. Do I need to replace the cable also that runs from the screen through the hinge to the computer. If so, what kind and where can I get it?

replacement cable? eBay, eBay, eBay!

My wager is that the cable (if it's not defective) is being twisted by your manhandling and is becoming slightly damaged leading to signal loss.
You might want to try purchasing a new cable (eBay, or your local Apple repair depot will be able to order them in for an ASSLOAD of money -- way too much) and having the hinge repaired (now here's something your local Apple repair depot can do).
The titurdnium powerbooks use a micro coax cable to carry the video signals. These cables are so fragile that simply pressing into them with your fingernail is enough to short the center conductor to the ground jacket.
Huh? I'm not sure what you're describing but whatever it is ain't in any of the dozen or so 400mHz - 1gHz TiBooks I've got sitting around my shop in various states of (dis-)repair.
Can you perhaps clarify your remark?
I do agree however that TiBook display data cables are very fragile and should be treated as such.

The individual wires in the LVDS bundle on those machines are actually really tiny coaxial cables. Cut one open and look at it under a microscope and you'll see. This is also why they are so fragile.
Yes I realize that they look like 30 gauge wires, but they really are coaxial.
Har, har, har . . . riiiiiiight! Sure, heh heh heh, lil' teeny tiny eensy weensy coax cables. Heh heh heh . . .
:o SoaB!!! :o !!
Ya know, I never looked that flippin' close before! Each cable is only about 0.3 mm in diameter, so them there's mighty small coax cables. Wow! Thanks drbob, 'tis nice to learn something new!
Haven't cut open any others (yet!), but I'm wondering if (all?) other similar-type cables have similar construction?

The titanium was the first to use that technology, but we were depertate to get away from flex cables. Most future products switched over soon after. I can say with relative certainty that if it looks likes a simple wire than it's probably a microcoax as they would never use a simply wire for transmitting signals at such high frequency.
I had the same problem but it was not the cable but the socket (the female on the logic board) when I pressed on it the display was fine- my guess is that it came in contact with the bottom case cover and this after a while made it loose (I can see some indentations on the aluminum-foil there). Taking a close look I could see that many contact of it where indeed not attached any more to the logic board. Some soldering (with a very steady hand) fixed the problem. - Does anybody know if there should be washer under the case-screw on the left side close to this socket (as there is on the right side)?
