Firstly as I'm sure you are aware, electronics without a surge protector is a bad idea.
I guess firstly i would check the power brick, what color is the light (when Xbox is turned on)?
Green means it should be OK
Orange or Red means you have an issue.
Light is orange/yellow - It is not necessarily a problem when the xbox360 power supply light turns orange/yellow as it can mean that the console is off and the power supply is connected to an electricity outlet, ready to power up the console the next time you feel like gaming. If this does not happen then it could mean that the power brick is not plugged into the console properly and there could be a loose connection. Steps to take to fix this:
Ensure the console is turned off
Unplug...
