RAZR v3x keypad doesn't work, except the On/Off button. Monitor is fine and can recieve calls, but phone is not very functional without a keypad, can't call, can't get to vast phonebook, etc. Wine spill was suspected as the culprit, but opened bottom and took out keypad etc. and cleaned all circuits with rubbing alcohol and dried, put back together but acts the same. Any suggestions on what to try?
