Something might Ben stuck the clicking sound can be the disc hitting the thing stuck inside. If there is somthing stuck the wii will spit out the disk use a flashlight and tweasers the take it out
Make sure plugs are all plugged in. Did u have a game in it? Try to get it out and try again. Or maybe you left it on last time you played which can overheat it
On your own there is no way of fixing this. Send it in for a repair. Leaks in DS could of burned it or over playing in. In case power supply leaked don’t play it until it’s repaired
