The connector that connects the first board to the lcd flex cable is slightly damaged because very fragile and didnt know how to unlock it. It should still be fine but can i use some kind of clip like a paper clip to clamp the flex cable to the board. Paper clip is much to strong.
i'm sorry dude, i can't understand your english enough to know exactly what you mean is the problem. can you post pictures?
does anyone here speak portgugese? maybe they can help you.

I understand
There are two main types of FFC socket: The good type has a piece that you push into a solid body to lock the cable in place. The bad type has a hinged flap that you close on the FFC cable. Those have tiny plastic locks on the corners to hold the flap closed. Both the hinges and the locks are very easy to break.
Since the LCD monitor manufacturers "servicability plan" is for you to just buy another monitor, they use the cheaper flap sockets. (That saves them about 25 cents US!)
I broke one of the locks on my LCD, but one lock is enough to hold the flap shut. If you can invent something to hold the FFC cable tightly against the socket contacts, then you can save your LCD. As long as you still have the flap, then you could try holding it shut with a small piece of rubber, with a piece of metal or plastic glued to the board to push against the rubber. But there are other alternatives:
You may be able to have the socket replaced, if you can find the exact part (maybe Digikey.com?) and a really good electronics technician. If you can't find a replacement socket, then a good tech could solder wire-wrap wires between the board and a better "push-in" FFC socket. This kind of repair has to be done with a temperature-controlled soldering iron under a microscope!

Yup thats the one I have. I still have the hinged flap and when I close the flap it still seems to hold the FFC cable in place but probably not very well. The white corner thingys are broken on both sides. Had I know the flap flips up this could have been avoided.
Not sure what you mean with holding the flap shut with rubber. The flap stays shut just not locked tight due to the missing plastic sides.
Are you saying get 2 small pieces of rubber, place them on either side of the hinged flap in the closed position and then get a small clamp to hold the rubbers tight against the flap on either side?
I was just thinking to clamp the FFC cable to the board just a little past the white 2mm line.
I took another look. Ok the sides of the socket lock still has a bit of white sides so its not as bad. Second the flap actually slides in on the top side before you flip it down to shut. Looks like its still holding the ffc fine. When the flap comes down to lock it looks like its locking due to the small white plastic borders left and right. So its not all gone. I guess i just broke the very small pieces on the top. Ill tell you i think everyone can make this mistake if you dont know how to open the socket.
I thought it was a socket that pulls out. I was very gentle using a watch screw driver to displace the ffc.
Sorry i dont have digital camera still.
You could use a binder clip like this one:

clamp
Actually, I meant something like a very weak binder clip with some flexible material (like rubber) between the clip edge and the flap. You can't really use a binder clip, because the FFC has to come straight out from the board. But you could fabricate a right angle spring-loaded clamp, or maybe a single-sided bar clamp bolted into machine nuts that are glued to the board on each side of the socket. The rubber between the metal bar and the flap would distribute even pressure all along the flap.
The whole point is to find a way to keep the flap held tightly closed, but not damage the board or FFC.

go to a machinist, they might have an idea, like using a set screw and u shaped clip out of metal.
machinists can figure anything out.
