A controller that does nothing can make the whole console look broken even when the video output is fine. Work from the physical connection outward: batteries or charge, receiver, USB port, pairing state, then player assignment.
Confirm the controller has power
Replace or recharge the batteries and check any power switch or indicator light. A weak battery can sometimes light an LED without maintaining a stable connection.
Find the correct receiver
Many 2.4GHz controllers require their included USB receiver. Make sure the receiver is inserted fully and belongs to that controller set. A similar-looking dongle from another device may not pair.
Try the other USB port
If the console has multiple USB ports, move the receiver and reboot. This separates a port problem from a controller problem. Do not force a connector that does not fit cleanly.
Reset pairing in the documented order
Some controllers pair automatically at boot; others require a Home, Start or pairing-button sequence. Follow the instructions for the exact controller revision because button combinations can differ by supplier batch.
Check player assignment inside a game
A controller can navigate the menu but still be assigned incorrectly for a two-player game. If one controller works in the interface, open the system’s controller/player settings before assuming the second pad is defective.
