The keypad membrane is easily removed by opening the case. Check the contacts and clean the board and the keypad with some alcohol. See the details below.
Also, try a throttle reset. To reset any NCE throttle, including the Power Cab, hold down the "select loco" key while plugging in. To read or change the cab address with the cursor blinking, use 00 to reset the cab to factory defaults and Cab address 2.
The “contacts” under the Buttons on the Throttles get dirty over time and are easily fixed. Disassemble the Throttle and separate the keypad Membrane from the Circuit Board.
Clean all 35 “contacts” (Pro Cab / Power Cab) by applying some Circuit Board Cleaner, isopropyl alcohol, or something similar to a piece of cloth and lightly rubbing all the contacts. Leave the Circuit Board to dry off.
Clean the Keypad Membrane in the sink with warm water and some detergent by gently washing around the recessed black domes. Dry with towel and let the Membrane completely “dry out”.
Re-assemble the Throttle, and your throttle will work like new.
Replacement keypads for a Procab / Power Cab can be ordered here
To send a cab in for service: No call or RMA number is needed. Include your contact info (phone/email) and a description of the problem.
