iMac screen going down

[Shtekeris]

I have white(!) 20" iMac, but now the screen just won't stay in position i want.
like, if i turn my screen to look totally up, after a while it goes down looking totally down. I want it to stay in fixed position. But it does not! Son of a !!!

Visual example:

So, any suggestions on how to fix this thing? Whats wrong with it ... Can i even fix it at home or should i just spend a lot of money on this ... THING ... and let some pro fix it!

I could be wrong on this, since i don't own an iMac, but there should be a screw at the pivot point that you can tighten a bit.
