Is your Wii power supply broken?

I just got a brand new 40" LCD TV (which, by the way, is awesome) this morning and started testing it out. First the PC, then the Xbox 360, then the PlayStation, and finally I tried turning on my Wii and nothing happened. No lights, no sounds, nothing.

So, I started troubleshooting:
  • Check the connections to the Wii; looks good.
  • Change the surge protector socket it's plugged into; no change.
  • Reset the surge protector; still nothing.
  • Measured the voltage in the socket (any excuse to use my fancy new volt meter); a solid 110V.
  • Measured the voltage from the power supply; a solid 0V. Bingo.
At this point I was releived to find that my Wii was most likely not dead. This evening I started looking into repairing power supplies. I found a couple sites that gave me hope, so I decided to crack it open and see what I could find. That's when I discovered that my BX-100 bit set was missing the appropriate bit for the screws Nintendo used. Flabergasted, I found Chris Meyer's site which suggest just using needle-nose pliers. I found that wire snips actually worked best since I could grip the dimples easily with the sharp edges. The hardest part was actually popping apart the plastic pieces (I suggest a butter knife or a metal plaster spatula/scraper).

However, what's more interesting than his instructions are his results. He and I both found nothing wrong, put the brick back together, and then discovered it was magically working again. This could be a coincidence, but I think it's more likely that simply leaving the power supply unplugged for long enough allows it to reset.

With that, here is my suggestion if you find that your own Wii power supply has suddenly stopped working: before you tear it up trying to fix it, just unplug it and go outside to play instead. Maybe when you come back, it will love you again.

  2. Same here, measured the output of the powersuply, nothimng. I search the internet and found youre article. Left it unpugged and shorted the output (to drain the capacitors). Plugged in and it worked again.

  3. My Wii supply acts somewhat differently. If I leave it plugged in, the power supply is usually dead when I want to use the Wii. If I unplug after every use, the PS is fine when I next go to use it. It started this about a month ago, right about the time the warranty expired.

  4. This is exactly right. After several brief power "flickers" caused by a thunderstorm, my Wii stopped working. After unplugging it and following the advice here (I like to think of it as the "Little Bo Peep Method" of leaving it alone...) everything was back to normal and worked fine.

    Thanks for the post!

  5. Thanks for this write up. Exact sane problem here: thunderstorm causing power outage. Unplugging the power supply and now it's working like a charm. 220V here btw.

  6. Hmmm...same scenario. Thunder storm, flickering lights, power outage (30sec at most). Later went to use the Wii and it didn't work. Was plugged directly into wall (why? kids?). Unplugged PS from wall and back into UPS, no change. Unplugged PS to check it with volt meter next day. Should have 12V DC output but I got 30V DC. I am affraid to plug it into the Wii for fear of frying the Wii.

  7. damn I love the internet. I opened this site in one tab and amazon.com in another so I can purchase another Wii power supply. Luckily this site loaded first and I read it. Took the advise and went and plugged the Wii power supply into the outlet,,,,SOB it worked! Mind you I am very mechanically/electrically inclined, and the wii has been setting idle for a month now, there for I fell really dumb about now.

  8. OMG thank you sooooooooooooo much! I so liked freaked out because I thought it might have shorted out because of the storm we had last night...but then it didn't effect my ps3 or my 360. OMG as like a girlgamer this freaked me out. thanks for the help!

  9. Check Nintendo's site... They have specific instructions for resetting the power supply that state it must be unplugged from both ends for 2 minutes or more. I have had mine dead several times when we wanted to use the Wii. After taking the unit to the workshop, usually after several minutes of looking it over, I would find that it came on when I plugged it in.

  17. SHAZAMM! Wow what a life saver. Went to play WII and it was dead. Did a search on internet for "WII power supplies" and noticed the link for this page. Read it, disconnected both ends of power supply and timed 3 minutes. Plugged it back in and VOILA! IT WORKS!! What a life saver! "Don't you just love it when a plan comes together?"

  20. WOhoo! Saturday we were doing some electrical work and my husband shut off the breaker that powered our Wii. I couldn't power it back on. I went next door and used their cord...it worked. Came home and my cord still didn't work. I heard if you used someone else's cord to power it up yours would work. Not so. I borrowed their cord for the night. Today (monday) I read this and tried. Wah la! It worked! BTW, Amazon had a new cord for $6 (+shipping). Yay for a working Wii.

  22. Ha! Got on here to buy a new cord. Dug the old one back out of the trash can just in case by chance I had not unplugged the thing from BOTH ends at the same time. Low and behold I had not. Thing works fine. Thank you!!

  24. Ain't the Web wonderful?

    Big thunderstorms here the other night. Today...no Wii power. I sat down to order a new power supply, and thought to surf for a similar problem. Here it was! Perfect fix. (I also unplugged the unit and shorted across the low voltage side... I like quick results!) Worked like a charm -- Thank You!

  25. I was just wanted to buy a new power supply but read your article. I just unplugged the power supply and shorted the 12v + and - for about 3 seconds. IT WORKED! My Wii is working now. Super! Now tell the good story to the kids.

  31. After a thunderstorm a month ago the Wii shut off and wouldn't power back up. I had unplugged but guess not both ends. So I unplugged everything completely... Waited 5 minutes and WE HAVE POWER WOOHOO!!! Thank you so much, and my 3 children that have been Wii-less for a month thank you too!!!

  32. Wow! Same issue. Storm and then no power. Found this site after looking at walmart and amazon. Went to read the commenta to my hubby. Disbelieving as he is, he loves me and tried it. Wow! Works perfectly and scores points with the hubby! A million thanks!!

  33. Wow, so many people with the same result. I just love it when things mysteriously fixes itself. Mine had the same problem.

  34. I was about to go and buy a new power cord, and this popped up on my search. It WORKED!! I just plugged it back in, as I had removed it, and trashed it already, to my kids chagrin, and it's like magic! :-) Thanks!

    ReplyDelete
  35. Thank you! Worked a treat, though I don't remember a power fluctuation, but at least I have a solution. Reminds me of when I had trouble with a laptop seeing the battery. Solution there was to unplug it for 10 minutes.

  36. I cant beleive this. Same thing happend to me. Was just about to order a new one, and found this site instead. Retried the power supply, and it worked. Thank you

    ReplyDelete
  37. Me too and it worked fine. just unplug for appox 30 minuts and plug it back in. Thanks for your help.

    ReplyDelete
  38. Same thing with me I used to do what you did for a long and I really think that this is a trick by nintendo especially because this happened after the warrant.y

  39. This worked for me too!! Had a thunderstorm, power outage for 15 seconds then power back on. Wii was even plugged into a surge protection power bar. Dead - narrowed it down to the power supply. I can't believe it, I was about to shell out for a new power supply and I thought - hey might as well try as unlikely as it is to work. Worked like a charm! Thanks!!!
