Replacing a laptop LCD

Did you try to turn it on when you had just connected the screen and not put the machine back together? Maybe you cracked the solderings when you put it back together and that's why it doesn't work?

I think it wasn't broken in the beginning but some of the wires were loose (likely a result of pulling the connector cable out of the old screen), but I didn't notice until later.
Yes I did try to turn it on before putting it back together. Well, I at least mounted the screen without putting the case back on.
The soldering shouldn't have been affected by putting the case back together but I think I might have cracked it when I tried to push the connector in a bit too firmly.

However, could the malfunction be related to what cracked the LCD in the first place :-\
A cracked LCD screen sounds a bit extreme to me.

Heh, I highly doubt that dropping the laptop would have any clue to the problem, especially if the old screen still worked aside from half of the screen, which showed some fancy colors and a haphazard black shape.
Any LCD screen can crack from enough of an impulse force.
JoonasTo:
So why did you put it back together if it didn't start?
Or did I misunderstand something?
I'm out of ideas currently. Something came into my mind just before going to sleep last night but can't recall what it was. :P
Freedom Kira:
I thought maybe the laptop detected that the case was taken apart and refused to start. Obviously not the case :P

You're right it's the screen alone, or was before you dismantled it, given this.
Even if the screen isn't hooked up properly, you should be able to power the laptop on okay, just not seeing anything. If it's starting to power up and cutting out, you might have a loose wire or a short somewhere or the battery may need charging. I'm assuming you left the cable in and allowed the battery to charge a bit before trying to turn it on?
Your first problem is getting the laptop to turn back on with either the old screen or no screen, if you can do that, then you know you haven't introduced a new problem, like a bit of solder floating around the case somewhere or too much pressure at some point when screwing stuff back together that's causing it to cut out during POST checks (does it get as far as making a beep of any sort when trying to power it?)
Someone might be bale to help your more easily if you could put up a pic of the connectors on the new screen, particularly showing detail of the damage you are talking about. But again, a broken screen should not be stopping the thing booting.
A lot of BIOSes are set to allow both VGA and LCD output by default, you don't expect an incompatible screen to case a shutdown, but it can't hurt to see what happens with if you hook it up to a standard CRT monitor, I've actually found this useful in the past simply for verifying the components around the mainboard were working correctly before attaching the new screen. (I had a similar problem following an "accident" with an annoying youtube video and a slightly overzealous gyaku tsuki)

Totally off-topic but I just had to quote that.
