Original xbox 360 red light blinking please help

enter image description here Please help. Im watching videos and they have 3 blinking lights, i have 4. Its an original xbox 360.

Solution 1:

This is an issue with the AV cable. Basically, the Xbox does not detect an AV input.

You can potentially fix the issue, with one of these solutions

Disconnect, then reconnect the AV/HDMI cable.
Wipe down the contact area for the input, and if that still does not work, try a different cable.
Flush the cache

There is a high potential that this is caused by overheating, which needs to be dealt with, advisedly by a professional, but it can be done yourself.
