This is a strange one...

My missus's cat knocked her laptop onto the floor and now the screen doesn't exactly work. When you boot the machine up it activates the backlight a little bit, but it all stays black until Windows gets to the login screen where it displays a nice and clean turquoise image, and nothing else.

It isn't cracked at all, so I'm thinking it's a connection that is now dodgy, it outputs via VGA fine, but it means her laptop isn't so portable now. :p

Any ideas as to what can be done? I'll probably be claimed on house insurance, but even so, would be good to be able to fix it, saving on the insurance claim and all. :)

sounds like the cable has come adrift, theres a connection on the back of the lcd itself and one on the mainboar, both will need some stripping of the unit to access and reseat, not overly difficult but some care is required when removing the lcd bezel as they are rather thin and break easily.
 
Ok, sounds like an easy enough job. I've had fun doing similar fiddly jobs, I had to take a mate's mobile apart and replace the screen, that was fun.

I'll see if I can persuade her, but she doesn't seem too keen on me taking it apart. :(

Ok, I have the laptop in front of me, I've taken out all of the visible screws, remove the HDD and DVD drive, and battery, and the bottom of the laptop will not come off, it appears to be attached still, which doesn't make sense as there are no more screws.

Also I can't spot any screws on the bezel, unless they are covered by the rubber pads (which don't seem to want to move just yet).

Any help greatly appreciated. The laptop in question is a Presario C300

On a some laptops, to get the bottom off you just have to prise it off with a flat head screwdriver or similar as they tend not to be attatched with screwdrivers but rather clipped on so they're not as easy for the average user to just remove whenever he wants.

Try gently levering it off with a flat head screw driver.
 
I got all the levering bits off, but there was something right where the graphics card/cpu is that would not let the base go.

I have since making my previous post, done a quick google and found that I don't need to remove the bottom of the machine to get to the screen...I just need to remove the rubber plugs and some screws on the screen itself...talk about making a mountain out of a mole hill. :D

yes remove the screen bezel pads and take the screws out, gently prise the bezel using your fingers around the inside of the screen, then there maybe a few more along the top edge in order to get to the back of the panel and to the connector.
 
Just thought I'd post some pictures to see if anybody has any idea as to what is wrong.

It appears to be outputting the central line of pixels from left to right, across the whole of the screen, so repeating the line of pixels giving a blurred view of things.

Booting up...

In Windows...

Windows via the VGA output...

So it isn't the graphics card playing silly buggers. And all of the connection on the back of the screen are fully connected still....

This means I want to check the connection on the laptop side of it, rather than the screen. So if someone knows how to take the underside of the laptop off that'd be great, as I can't seem to work out what is holding it on as I've removed all screws and clips that I can see.

It's being held on by something around the circular vent area in the picture below...

It would be nice to be able to fix her laptop, as it defeats the idea of it being a laptop/portable if she needs a separate screen to run it.

you dont need to take the whole thing aprt for this, under neath near the rear edge look for screws with a small triangle next to them usually 3 or 4 and some in the battery bay, they hold the keyboard stripcover on, then just gentely prise it up and to the left should be the lcd mainboard connector
 
I currently have the laptop like so...

Got to go out soon, but it appears that all the cables/wires are attached and in full working order...this is really strange.

The connection on the top of the laptop is still in place, it doesn't appear to have ever moved, and the one on the underside appears to also be fine.

Whatever Warranty that was on there would surely be voided now.

Thats a known issue with that model, definatley a problem with the TFT display and not the VGA card itse;f I'm affraid. See a lot of these come in to work with this problem. If it is still under warranty I know Compaq turn around is pretty good, usually takes about 10 days and you get your laptop back with the parts fitted, properly :)
 
As far as we are aware it had run out of Warranty, hence me taking it to bits. :)

She'll just have to put up with a non portable laptop till she can get a new one...as looking at ebay new screens are rather costly.

Cheers for the help with it though. :)
