good friend, if you have already tried with the sinto and the eeprom, remove the buttons, sometimes they get a little resistive and cause that failure, test and comment

amigo.no before checking the diodes and resistance of the area from the micro to the swich. If everything is good you can do what you indicate or try a new and recorded eprom with the micro data.
