Having had this problem and thought it impossible to undo the LCD screws, I managed it. I did this with a regular cheap Y aka 3 point screwdriver that came free with the replacement LCD.
The steps are as follows:
1) Place the backside of the screw (and so the LCD shield edge) against the edge of a table/bench. This is so you can push down in the screwdriver with enough vertical force to have it stay engaged in the screw.
2) Observe where the three slots of the screw are aligned so you can tell if you have moved it at all after step 5.
3) Place the screwdriver carefully so the 3 points on the screwdriver line up with the slots in the screw.
4) Push down very hard vertically to engage the screwdriver in the slots.
5) '''Slowly''' turn the screwdriver. You only need to turn it no more than 90 degrees (quarter turn) to break the initial torque/thread lock.

6) After step 5 the screw should be loose. You do not need to exert too much vertical pressure anymore. it should spin out quite freely.
