purely coincidental, the wii wouldnt have cause the sound failure, your dvd could have been playing and the same thing would have happened, connect the wii up it will work fine

Are the drums blinking? If so it is not the batteries, it could be not synchronised with your wii. If so press the orange buttons on both the wii and drum set.

Hi there, you could try the following:

1. Try unplugging Wii from the power for a full 2 minutes, plug back in and power up and test (This resets the Power Adapter).
2. If this does not resolve it then it may need to be repaired so contact Nintendo here.

Please see here for for information on Power issues with the Wii.
Cheers

I dont know

I suggest going to the Local Electronics/gaming store, i had this went to them and they said that one of the fuse's was burnt, Try that if not, call nintendo and kick their ***** !

Perform the Wii 'RESET'.

1. Unplug the Wii for at least 5 minutes.
2. Plug the Wii back in and try to use it again.

If Wii gives Disc Read Error, first step you need to check is to try another disc or clean the exisitng disc. This will confirm that problem is with either Wii or Disc.

I just answered a question that may be relevant to this one so here we go I'm gonna copy and paste a solution I think may help you.

The accelerometer in the wii may be stuck, which does happen from time to time.
To fix this turn the Wii remote so the buttons face towards the floor and slap the back of the remote firmly(not too hard!) with the palm of your hand. It should work if that is the problem.
*make sure to hold onto the Wii and not let it fall*

Try it again and if that fails contact Nintendo at 1-800-255-3700 they have amazing customer service and your call should conclude with satisfying results.
