Hi
If you can dismantle it and pay close attention to the buttons
If you get some isopropyl alcohol and some cotton buds you will be able to clean it up and it should work well again
I would also clean the traces (should be on a thing plastic piece) with some isopropyl alcohol too just in case
Hopefully this helps
Any questions please ask
Thanks:-)

My guess is unless you're familiar with disassembling and repairing electronics, this may be well worn out unit to consider replacing it altogether.
