I replaced the keyboard and the KEYPAD MEMBRANE STICKER PCB Mylar and I cleaned under the keyboard with rubbing alcohol let it dry. The keys worked for about a day and stopped again! so frustrating!!!! There is no water damage the stickers are still white. What else could be wrong?

OS problem?

It sounds like you don't have a hardware problem. Is this still underwarrenty? Have you considered if any apps have caused a software/OS problem?
