WiiU Red Flashing Light – My problem, and how I fixed it

So to those other 7 people who own a WiiU out there, let me give you some advice. Don’t have a HDMI cable pull one way or another whilst connected to the console, even slightly. You’ll see why later on…

So I’ll walk you through the issues I’ve had over the past month or so with my WiiU. I had been living away from home most of the past academic year whilst I was studying (aka lazing around) at university. When I came home, one of the first things I did was turn my WiiU on to play it. The problem was, it didn’t turn on. The light just blinked red.

Like most sensible people (not that I am one), the first thing I was google the issue. I found it could be one of 3 things

  • Poor ventilation (dust in the vents, over-heating, etc.)
  • Faulty power supply
  • Motherboard issue (I immediately dismissed this one, but apparently “motherboard issue” can cover a very wide range of things)

The first thing I tried was a fix for the power supply, which was to let it ‘reset’ by having it disconnected from the console and mains for 90 seconds. Didn’t work. The next thing I did was take a look at the vents, and sure enough after months of sitting on its own, it had gotten dusty. I gave it a quick blast with some compressed air, and it worked!

So if you’re experiencing the Red Flashing Light of Death (or RFLoD as we’ll now call it, should we mention it again), letting the power supply reset or cleaning the console could be your fix.

I thought this was the fix for my console, but sadly, it was not. I took the console to my girlfriend’s house a week or two later (not having played it much since I got it to work) and it didn’t work. I assumed it got dusty in my car or something, so we hoovered it (yeah). Didn’t fix it. We left it for a while, tried it again… and it worked! This is what starts my belief in the power supply being at fault.

We then go over to my house later that week (or the next week, fuck knows) and she wanted to play Wind Waker again. It didn’t work. After about half an hour of plugging cables in and out, swapping between mains sockets, fucking everything, it still didn’t work. I then ring Nintendo support, and they don’t suggest anything other than to send it in. The problem with sending it in, whilst it’s free to do so and get a diagnosis, the repairs are not. My WiiU is half a year out of warranty, meaning the repairs range from around £50 for a ‘minor’ repair to £140 for a ‘major’ repair. Another issue is that the vWii on my WiiU is softmodded, and there’s no way of virginising it (I could hide it somewhat, but a Nintendo engineer would easily be able to see that it’s been softmodded, if they were to check). So a combination of the cost of repairs and the fact I’ve broken the terms of service made sending it in a last resort.

A while after I tried the console once more and… it worked. Again, I put this down to the power supply because leaving it alone for a while and plugging it into a different mains socket appeared to fix the issue. Over the last week or so there have been occasions it has decided to work, but for the most part, it persisted to have the RFLoD. What was really odd was that if it had been off all night, it would always come on again in the morning when I tried. I was really baffled, and was sure it was a faulty power supply. I then borrowed a multimeter and testing the output, and it was as it should be. So what was the problem? I was still thinking it was a dodgy power supply, or mains outlet.

I was very close to buying a new power supply (since I don’t know anyone else who owns a WiiU) but I decided to do some testing first. I’d managed to get the console to work earlier today (during which I backed up all of my files in case it did have to get sent off to Nintendo), and when I turned it off I tried turning it on again. Sure enough, RFLoD. I then unplugged it all to let it reset, and whilst doing so I unplugged the HDMI cable on a whim (because this morning when it actually came on, there was no picture – the HDMI cable had come loose). The console turned on! I did about 15 minutes of testing, with having the HDMI cable in, different HDMI cables, trying the composite output, having the HDMI in on just the WiiU and not the TV… many, many combinations. I finally came to the conclusion that having any HDMI cable connected into the console caused it to RFLoD, and it would work perfectly if I turned it on with no HDMI cable present. I could even turn it on, then connect a HDMI cable afterwards and it’d output video and audio perfectly.

During this whole process I was posting what was happening on a forum in the hopes that someone would have an idea (even before I whittled the problem down to the HDMI port). One user suggested that whilst I was away at university, a cable might have been left it and had been pulling on the port. I couldn’t recall whether or not it had been left plugged in, but taking his suggestion I decided to hold the cable to the right of the console (or in this case upwards, since whilst I was away the console was vertical, but it’s now laying horizontally). Whilst holding the cable the opposite direction it would have been pulling, had it been left in all those months, I booted the console. And it didn’t RFLoD. The forum user was indeed correct, the cable had bent the port over time and caused damage so the console was refusing to boot.

To fix it, I put a HDMI cable in and slowly, but with pressure, pushed the cable the other way and held it with pressure for 20s or so. Ever since, it’s been working fine. So,my advice to WiiU owners is to make sure that your HDMI cables aren’t pulling on the console. Don’t get me wrong, mine was just connected and pulled slightly to the left because the TV was to the left of the console. It wasn’t forced, it’s exactly how my PS3 has been for years and that’s had no issue.

So here are my fixes for the RFLoD

  • Check and clear vents of any dust
  • Check the power sully is outputting the correct values
  • Try the console with nothing plugged in besides the power supply (including USB cables, memory cards, etc.)

If the console boots with nothing connected when it otherwise wouldn’t have, try each thing individually until you find the one that’s causing the console to RFLoD. If it’s the HDMI port, try bending it the opposite way to which it would have been pulled. If that doesn’t fix it, but you’re sure it’s the HDMI port, you’re either going to have to send it off for repairs or replace the port yourself (would require soldering, but looking at images of the motherboard it honestly looks like a relatively simple job)

If not of that fixes the issue then it’s almost certainly something else wrong with the motherboard, for which I have no suggestions.

tl;dr HDMI cables can break your WiiU and why is it such a piece of shit, like really my N64 still works and that’s had thousands of hours of use jesus fucking christ

  1. Thank you it works, I start my Wii u without anything plugged in but the power cord. Than I carefully plug on after it is on.

  2. Finding your problem was remarkable! You da man! Unfortunately, mine is not that at all but maybe you can still help me. I can be right in the middle of playing a game with my son and then it just turns off! The “red light of death” comes on blinking! I usually just unplug the power cord until the red light stops then plug it back in and voila! Then 5 minutes later it happens all over again!!! Do you have ANY clue what might be causing this issue? please help!

  3. Hi thanks for the info. My Wii U flashes red as soon as it’s plugged in, without me touching the power button. It does not respond in any way when I press the power button. Just continues to flash.

    My gamepad powers on fine just that it can’t communicate with the console.

    The eject button also blinks once right when I plug in. I did have some dust on there so I used an air can and a mattress air pump for a good long while. I tried reseating the console battery.
    I tried warming with a hair dryer then plugging in while blowing. Nothing worked.
    Any other ideas? I really want this fixed!

  4. My WiiU works only in cold temperatures…
    I mena, after a hard rain in outside my house, and after put in the ventilator for 15 minutes.

    I tried it you describers, but, don’t work.

  5. Thanks for the troubleshooting tips but this didn’t work for me. I usually unplug the power supply and it starts right back up but now it’s not. I’m not sure why it’s doing this but it sucks. If it helps any I purchased my Nintendo Wii U on the first day of release. Any help is appreciated.

    • #81 Pyro:Better still would be for the â€norrcœeo” and whoever else was involved in the autopsy, the imam who issued the fatwa, the village elders, and of course the pervert and his lovely wife to all be locked up in the worst hellhole of a prison they can find. For life.I think that a “little hair of the dog” would be most appropriate here: the victim died after 70 lashes so obviously 70 is too many – but 69 should be just about right. After the hair of the dog punishment THEN lock the miscreants in the rat-terd motel for life.

  6. I’ve been trying to fix this for almost a year! please let me pay you the amount i would have payed nintendo, you’re amazing

  7. Same problem…different fix to those seen elsewhere.

    Red flashing light. Tried all the above. No luck.

    I took the little backup battery out then did a reboot.

    Success.

    Ps: battery requires you to unscrew the small panel on the side.

    • Looks like removing the backup battery may have worked for me too. I have been able to get my to work on occasion. But it booted right up after removing the battery. I’ll test the battery tomorrow and see if it is dead. If so I’ll order a new one. Thanks to all.

      • unfortunate turn of events. Not only is the battery 100%, but I have gotten the RFLOD even with no back up battery at all. :-(

        • It was cold. About 16 degrees. Wii u didn’t started at all until… I used the hair dryer to warm the console a bit via the vent outputs. Then it booted.

  8. It was difficult to find your site in google. You should create some high page rank contextual backlinks in order to rank your
    site. I know – writing articles is very time consuming,
    but contextual backlinks are the best type of backlinks. I know one cool tool
    that will help you to create unique, readable articles in minute, just search
    in google – rewriter creates an unique article in a minute
