I have had a wii for 2 years and it had been working fine until one day we can hear sound and now not get any video besides a black screen. We have checked and replaced the av cables so its not a cable problem. is this not fixable without sending it in?

It's probably overheating (fan is broken)

You can get a third party to replace it if you want, but I would actually recommend sending it to Nintendo.

Unlike Sony and MS, Nintendo has awesome repair services. They will do any repair under (1 year) warranty for free and if it's not under warranty then they will still do it for cheap. It cost me something like $96 (in Canada) after shipping.

They are also very quick, usually in a week you'll have your system back.

The best part is, whether your system is under warranty or you pay for the repair, you get a renewed 1 YEAR warranty with Nintendo, this is far better than Sony and MS who only do 90 days!

Your cables still could be going bad, even though everything else is fine I would go to a gamestop and buy a used cable and see if that works or go buy a brand new one.

You need to connect a composite cable from the receiver. The receiver does not carry a composite signal over component cables.

Make sure you have the input set correctly on the TV. If you turned everything off, it probably reset back to default input.

disconnect the monitor from the back of the system and see if u see the colour scheme or anything if u do see something that means monitor fine ... problem with system

If you can still HEAR sound, but can't see. Check your Audio Video Cable.

It's the colorful one (red, white, yellow) (red, blue green, white, red)

Make sure the connections are secure into the back of the TV as well as the connection to the back of the Xbox 360.

The following fix should help users who do have problems with some virtual console games for the Nintendo Wii that display only a black screen after starting them while the sound remains normal. This does not work in all occasions but should work if you get the Wii menu when you press Home and works only for games that received an update for the interlaced mode.
Try out the following to see if this fixes the issue. Start the game normally until you see the black screen. Connect the Nunchuck to the Wiimote and press Home to see the menu options. Now press A + 2 + Z together which should result in a short “ping-like” sound.
This should have activated the interlaced mode. Leave the menu and you should see the normal game screen and not the black screen anymore. To change the mode again press A + 1 + Z using the same method as above

Hi everyone, I just wanted to post a very simple fix for those of you who installed your Wii correctly, had it working fine, but then experienced a sudden all-blank screen (in my case, all blue, which I think is a function of my TV). I read all these alarming threads that made me think my brand new Wii would have to be sent in for repair. I tried resetting it, turning it off and on, unplugging it, etc., all to no avail. Then I unplugged the satellite receiver dish (even though TV was working fine), waited about a minute and plugged it back in. Once the box reset itself, voila, problem solved! I am not a tekkie but for those of us newbies out there, I hope I can help just one person!
