1. Check the power cable and ensure it is securely connected to both the amp and the power outlet. 2. Check the fuse and replace it if needed. 3. Check the power switch and ensure it is in the correct position. 4. Check the battery (if applicable) and replace it if needed. 5. If the amp is still not turning on, contact Roland customer service for further assistance.

Your Roland microcube AC is waste up

Unfortunatly the impact from a fall can lead to numerous problems ranging from a broken fuse to a disloged power supply to a cracked board.

The most likely problem would be wiring. By dropping it you loosened or disconnected a wire.

Rubber cement is an excellent for minor speaker cone damage but if you feel that a replacement is required, try MCM Electronics online. They carry lots-o-speaker replacements. Be sure to match wattage and impedance (ohms) of the speaker though as these are important spec's.

Check the fuses. There is probably one on the outside of the amp and some inside the circuit board.

Thee internal fuse should have protected it.
