after 10 years while playing and using it as a media center, yesterday, my son tried to turn the xbox on, without success.
just pushing the power on button, the xbox started, all the leds were on... but nothing more.
also by pushing the dvd button, the box starts, but the drawer doesn't open.
after hitting both sides a little bit, it started... (huh!! I'm a programmer and I work on POS registers since 20 years, but sometimes a nice knock works...)
I said, well, ok, now we are back! but today, the same, and no way to awake it.

so, now, from were do you suggest me to start?
actually no strange blinkings of the lights (standard controller ones), no sounds, no strange led colors..

thx a lot!
