Ok. When I yanked off the ribbon on the LCD, I got some gold things attached to the green tape like this:
I just wanted to ask if it was normal for those things to get pulled off. Here's the picture of the LCD and Circuit board after i took off the cable.
Altogether, I just wanted to ask if I'm still able to buy a ribbon cable and replace it. I don't know where the gold things came from. Hopefully, it didn't come from the phone. But if anyone had this problem, please notify me. Because I don't know if a new ribbon cable would still work. Thank you. P.S: Do you know where to buy a new Ribbon cable?

To replace the screen of the samsung g800, get there appropriate screwdriver and follow the process below;
Remove your back cover, battery, sim and memory card. Remove the
six screws (two at the bottom are covered by rubber stoppers
which are easily removed). You can now remove the battery compartment.
Below you can see the battery cover removed. You now need to
disconnect the circled ribbon connector. It attaches like a plug and
socket. Simply lift the connector up to unplug it.
Lift the circuit board up to reveal another connector. It attaches like the last one. Unplug this
You can now remove the circuit board. Note that the ribbon running
along the right of the circuit board, with the volume buttons at the
end, is lightly stuck down with a tacky glue or double sided tape.
Remove the grey part. Note that the ribbon with the
camera button at the end is stuck down lightly. Next remove the four screws.
Part of the slider can now be removed.
the two rubber stoppers at the top of the phone to reveal two more
screws. Remove the four screws.
Remove the ribbon which is stuck to the black rectangle. It'll just peel back.
Run your plastic tool all the way around the join of the front cover to
Lift the screen away from the phone at the point on the opposite side. The screen is stuck down lightly
with double sided tape.
You should now have the LCD removed.
Turn the LCD screen over and remove all the green tape you see. You now
need to detach a number or ribbons. The ribbon attaches like a
plug and socket. All the other ribbons have a hinge which you need to
flick up to release.
The reason your screen wont work is because there is a problem with the flexi ribbon that connects the screen to the panel of the phone.
To fix the screen, you would have to dismantle the phone and replace the flexi ribbon.
To disassemble your phone, you have to follow the process below;
Get the appropriate screwdriver(Phillips screwdriver, plastic
tool such as a guitar plectrum or credit card.),
Remove your battery cover, your battery, your sim and your memory card,
screws you can see.
Peel back the sticker. You may need
something with a thin, sharp point to peel the sticker back (samsungmobile.com). Two
rubber stoppers need to be levered out to reveal two more
screws that must be removed.
Run your plastic tool along the join of the battery compartment to
separate the phone into two halves. Next you need to
disconnect the ribbon. This attaches like a plug and
socket. Simply lift the connector up, away from the circuit board to
unplug it. Remove the screw by the left. You can now lift the green
circuit board away from the phone. A little force is required.
You should now have the circuit board removed. Note that
a ribbon, will have disconnected when you removed the circuit
board. Again, this attaches like a plug and socket.
Remove the identification sticker. Remove the volume
button which will be loose. The buttons underneath will be
lightly stuck to the side of the phone and need to be peeled away. Lever
off the grey part.
Remove the four screws you
have access to (one is under the ribbon cable).
You should now be able to separate the phone into two parts. Two rubber stoppers need to be levered out to reveal two
screws. Remove these plus the two others screws you see.
Run your credit card around the join of the housing to release it. Once
you have the two parts separated as far as shown below, pull in the upward direction (towards the camera).
Pull the little metal bars in the direction of the camera.
Lever out the camera, speaker and ringer. They'll be stuck
down with double sided tape. Lever out the the screen.
Slide your plastic tool under the green circuit board to release the LCD
You should now have the LCD screen removed,
Turn the screen over. Remove the green tape at the top. Now release the
circled ribbons. To do so, flick the black latches up and then pull each ribbon away.
That is the ribbon that needs replacement.
Reverse the process to reassemble the phone back together.
if the lcd and ribbon are seperate, then pls check the connections, if ok then its goof. However, if it does nolve the probelem, it is better to try new lcd and ribbon...to know which one is deffective.
Remove battery cover and battery. There are four small screws visible on the rear cover, remove those. Wiggle and distort the back cover a little at the bottom of the phone until it pull partly free from the phone, slide a guitar pick or small flat blade screwdriver between the phone and the rear cover, at the side of the phone, pry this cover off until it snaps free. You will see the main board now. Remove the two screws holding this board on, carefully fold it back towards the battery area. The main ribbon cable is visible now. Remove a green tape on the socket where the ribbon cable joins the board. pull the ribbon away from the board gently and use a screwdriver or something else to cut the adhesive between the board and the cable. The socket has a hinged brown piece closest to where the cable comes in, that flips up to release the cable. The small cable coming from the number pad is removed by gently prying up the rectangular connector from the board. Now with the board free you can remove six screws from the plastic backing plate, and remove that plate from the slider assembly (one of the screws is hidden by a piece of green tape). On the front half of the phone there are six small screws on the rear side (the camera side). Four are visible, two are hidden behind rubber plugs at the top of the phone. Separate the chrome trim from the backing plate by starting at the bottom of the phone, by the key pad, and it may be stuck from a little day-to-day dirt but separate it there, then swing the bottom end out and release the front cover from the two clips that hold the top end together. You now can separate the ribbon cable from the screen assembly in a similar way as you did with the other end of the cable. Reassembly is the reverse of disassembly. Be sure to replace the pieces of tape, and the wire mesh shield attached to them, they serve to prevent radio frequency interference between parts of this device, and between this device and others.
sounds like you need a new ribbon cable
1st buy ribbon cable from ebay
here are the instructions to change your ribbon cable
remove battery/sim card
undo 4scews tiny cross heads they are
slide phone open ans at the bottom of the phone theres 2 more scews to undo these are under little plastic covers
once removed starting from the bottom of the phone insert a thin wedge i use my fingernail just get it inbetween the bottom of the casing and slowly move it round the phone open the casing a little but not 2 faras you have 2 slide the casing off the tophalf of the phone
once you detached the casing there will be a plug(loud speaker)just unplug this
now you should be a stage where you have removed the back casing,we continue
carefully prize out the main baord this will be attached to a ribbon cable so be careful
remember to first remove the button and then run your fingernail where the buttons are affixed (there stuck to the casing)
ok you have the main board free now turn it over so as you dont damage the cable remove the green sticker which covers the cable then you need a soldering iron to free the cable as its attached to the main board flip up the holding strip and remove the ribbon cable from the main board
ok next there are another 6 tiny little screws which attach the sliding chassis remove them
and remove the slidehousing
ok now you need to undo 4 more screws 2 are in plain view the other 2 are hidden under the top plastic covers once they are removed the slide mech comes away freely and you can see where the the other end of the ribbon is attached again remove green sticker and desolder the pionts lift up plastic retainer and remove the ribbon replace with new ribbon and put back together the same way you undid it
sound a bit tricky but its quite simple really.
well i hope this helps
I just finished disassembly and it wasn't that bad. Take off all four screws around the battery, then carefully but forcefully take the plastic casing off. Then, take the 2 screws on the main circuit board. That will reveal one connection for the ribbon cable, take that off. Under that is the backplate sliding mechanism of the phone. There will be 6 screws on this assembly, one of them under cable the connects to the keyboarb (bottom right). You will have to take off a green tape and also a gold padding to get to this final screw. After that is off, you will see the other half of the ribbon. Take that one off also, just yank it off. Install the new ribbon tape, make sure you don't rip it, and you're set.
