touch pad control panel

Some of the key pad on control panel do not work. Mostly the center of the panel( numbers 1-9) with exception of #6 and 30 second touch pad. The time cook and auto/time defrost and 1 lb quick defrost are not workingeither. Everything else is okay. I have purchased a brand new smart box and it did not make any diference and my problem did not go away. Please help
