I am planning on modding a xbox for a friends birthday that is coming up and bought one from goodwill for $10. When I plug it in to power and to the tv and turn it on the green light on the front turns on and I can hear the hard drive spin up and possible the cd drive. However nothing appears on the tv. No sound, No video. If I hit the Eject button the green light flashes but never ejects. If I unplug the av cord it changes from solid green to flashing green and yellow and returns to solid green when I plug it back in. I know the cords and tv are fine as they work with other xboxs.
Any ideas on what might cause this?
