screws holding the housing together.? I don't have a teeny tiny phillips head screwdriver to remove the screws. Do they even sell screwdrivers that small. The wire of a small paperclip barely fits inside the screws.

you will need to buy/beg/borrow/steal a teeny tiny Philips screwdriver otherwise you will probably damage the casing or screw so even if you undid the teeny tiny thing you would be unable to put it back together again.

you need a electronics technician
