I'm not permitted to post a link, so just go to YouTube and look for the video called "Blackberry Curve 3G 9300 / 9300 Screen Replacement Take Apart Guide " from RepairsUniverse. the hard plastic tool is VERY handy, I tried using other things like screwdrivers and damaged the housing a bit.
As I said, the OP's device is almost certainly water-damaged. Replacing parts will not change that. It's not worth the effort or the money.
