model NN-SN966S Lost all control of the keypad exept Reset
Metin:
First, out of the blue, the display screen showed the Power Level counting down repeatedly (P 10, P 9...) while at the same time the speaker was sending out a continuous beep, beep, beep.
When I unplugged the device for a couple minutes, then plugged the power cable back into the socket, the display came up flashing and showed 88:88. I pressed every button on the keypad and only the Reset button worked clearing the display and showed : and again none of the keys on the keypad worked.
Anyone have any ideas? I'm thinking maybe the keypad failed or possibly the microprocessor. Is this even fixable?
