Four lights flash red on your original Xbox 360 console
Four lights around the power button flash red on your original Xbox 360 console. Four flashing lights mean the console doesn’t detect an audio/video (A/V) cable.
Solution 1: Disconnect and reconnect the A/V cable
There might be a problem with your A/V cable. The A/V cable connects the console to your television.
Disconnect and reconnect the A/V cable
Turn off your console and television.
Disconnect the cable from the A/V port on the back of your console.
Unplug the A/V connectors from your television.
Reconnect the A/V cable to the A/V port on your console.

Turn on your television and console.
