The screws are TORX-6 I think, my screwdriver says T-6 and was perfect for removing the bottom screws

I just successfully fixed my TI which had about half of the horizontal lines completely dead. I opened the calculator and used hot air gun to carefully warm the connection between the black ribbon cable and the board behind the LCD. All the bad connections were between the board and the black folded ribbon cable.

After warming it up I used a blunt small plastic object to glue the ribbon back to the board. The purpose of the hot air is to melt the glue.. The connection in question is hard to access because it is between the fold so you have to remove some of the black tape before you can stick something between the folds and access the connection.

Good luck Smile
