Backlight not working until I push top-right corner of the screen

Hi, I bought a 3GS off a friend and I have a problem with it. My backlight won't work, everything else is working good except the backlight. If I push on the top-right corner of the screen and lock/unlock, the backlight will go on. If I release the pressure on it, it will go off. Here is a picture of where I have to apply pressure to make the backlight work.

Could anyone tell me which connector needs to be pressed inside the iPhone so I could maybe shim it so the pressure is always there?

connector 1. It often pops up when you're closing the display after repairs. sometimes you get a plain metal connection, Most times it has a thin (1mm?) piece of foam that the rear of the display assembly sits against, it is this pressure that keeps the connectors on completely. If this piece of foam is missing, or the connection has come loose from a drop or repair, it might be why the backlight is working when you press top right.

It is the connector labeled 1.

Have a look at the 3GS teardown to see where it is located. It is marked with a red label and number 1 in the iPhone.

Most probably you just need to press the connector back into the socket. The connector tends to come loose a little sometimes causing these intermittent problems.
