Hi friends, referring to the origin of the tread, the msg of Lee Jones, I have been the same problem of miss contact on the cordless phone (Daewoo) and on the IR television remote control (Philips). After opening teh two keypad, I have found between the rubber and the PBC some liguid that seems oil, but believe me, no member of the my family put oil on telephone or remote control. After cleaning with more accuracy and delicacy the PCB and the black rubber spot all the two keyboard return to work correctly. But I'm curious to know th origin of the oil. I think a possible sweat of the rubber ?? Ciao Leo
