I was gutted earlier this evening when a bright green line appeared on my PowerBook's screen, about a fifth of the way over from the left, top to bottom, one pixel wide. I've done a number of restarts, advised by the Mac types in #joiito to hold down certain keys whilst doing so, but no dice. The line remains when I move the screen back and forth, but if I push on it just so, on the top left of the screen downwards towards the hinge, it vanishes temporarily, which makes me believe that the problem may actually be in the left-hand hinge. (This model, a G4 TiBook, has two hinges on either side, each with two screws in the back.)

Does anyone have any advice? Can anyone recommend a good Mac place in London that could look at this and won't charge me a small fortune to do so or take my Mac away for days? My life is on this Mac. I can't work without it, (not metaphorically but literally), and I can't afford not to be working right now. Because this Mac is both pretty old and second-hand - I was given it by a friend and have added a new battery, memory and an Airport card - I don't have AppleCare, so there's no chance of getting this fixed for free.

I am so sad, so disappointed. I mean, the thing's usable, but I can't really afford to get it mended, and I can't afford to buy a new one. If everyone who visited Chocolate and Vodka donated a single pound, then I could get a new PowerBook, but people don't. Someone once told me that it's easier to get one person to give you a million pounds than to get a million people to give you one pound. Scale that right back to two grand, and the principle is the same. A big thanks to those who have given me money for this, but if you have any spare right now, please give it to the Asian quake relief efforts instead.

I suppose I will get used to the line in due course and filter it out, but it's not nice and I worry that it'll just get worse and then the whole screen will go.

UPDATE: I plugged the laptop into my desktop monitor this morning to see if the green line is still there, and it's not. I presume this means that the problem lies between the video card and the screen and not with the video card itself, which may or may not be a good thing. I still think it's a connector. I just need to find someone to look at it and tell me for sure.
