I think this a problem related to the flex cable that connects the main phone body to the sliding screen. Over time the flex cable wears down as it slides and results in a whole range or problems such as: display acting weird (eg. mirror-image and inverted colours), speaker not working, off-button not working etc.
Flex cables are cheap to buy on ebay (a few dollars) and there's internet sites that show you how to open the phone and replace them. (google: samsung u700 replacement flex cable)
next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all.

take all the screws out and then carefully pry it open. it will seem like it wont open but it will. then the ribbon will have a flap to enable it to be free
The You-Tube video is useful. http://www.youtube.com/watch?v=dP0Yr4YXM9Y Care must be taken when removing the ribbon-cable connector from its mating half on the camera ribbon-cable. The black strip on the mating connector has to be flipped back, away from the display ribbon, to release the display ribbon. Then after locating the new ribbon fully home, the same black strip has to be flipped forward in the direction of the display ribbon and pressed down to clamp this connector in place. All this is shown, but quickly in the video. Do not touch the bare surface of the new display or the inside surface of the removed display protective surface which has an optical coating which easly shows fingerprints.
I had the same problem with my U700, when I cracked it open I noticed my flex ribbon cable was torn. So I ordered a replacement one from ebay, cost me about $15 (Aussie Dollars) and now it works fine. Hope this helps.
Yes, most likely you have missed the proper technique of installing the ribbon strips correctly into the connection block. I did the same thing and it took me three tries to get it right... I stumbled on this by playing with other ribbon strips on the phone that I could access better and found that there is some sort of “step” or “threshold” inside of the connection block that makes you feel like to have "seated" the ribbon strip at the bottom of the block when in fact you have to push harder to actually push the ribbon into the block fully and make contact with the connectors, and then snap the locking bar down. It's an easy mistake to make since the connection block and ribbon strip for the screen are hard to get hold of with your fingers... try using some tweezers or small long nose pliers to hold the ribbon and seat it fully. Now I still am trying to figure out how to unlock and install the touch screen ribbon into the connection block… it’s really small and does not seem to what to unlock to allow for a full installation of the really small ribbon strip and lock it in, so I used a piece of duct tape to hold it in place and it works fine… not my perfect fix on this one, but my ph works… Robert R.
to remove the top screen the back cover actually slides off after removing all the screws from the front, once thats off you can see the ribbon cable coming through the hinge, what you need to do is coil the ribbon cable up into a tight little roll and push it through the hinge it's easier if you pull the two little cables out first. hope this helps
my lcd turns off when i slide up my phone but it turns on when i slide down again
