well I took a clean tooth brush and gently removed the corrosion from the circuit board and put back the screws together and now it works like a new one !!! watch out when you open it, once you remove the circuit board from the casing nothing hold the buttons and they flew into the air when I opened it. probably from beer leaks hmm I mean battery leaks. I had the same issue with my ti-83+, I opened it up and realise there was some corrosion on the circuit board.
