Problem after modification

I think that the Wi U console that you have bought is broken and you will have to bu another Wii U console. Lukie Games and DK Oldies and East Starland Games and JJ games sells Wii U consoles.

MTU, or Maximum Transmission Unit, specifies the largest unit of data that can sent over the network. While this setting is not generally required for the Wii console to communicate with a wireless network, if you are having trouble connecting or maintaining a connection, setting this value to "1500" may help.

The simplest thing to do is to use StartPatch, if your Wii is running System Menu 4 or higher, or StarFall if you're running System Menu 3.2. (To check your system menu version, go to you Wii Settings; the version number will be on the upper right.)
These applications can apply various modifications to your Wii, including one that will allow you to play import games and another that turns off the annoyingly repetitive system menu background music. There is also a modification that prevents the Wii from checking to see whether a game disk includes a system update. If you use StartPatch/StarFall to install this modification, you will no longer have game disks insisting on updating before you can play them.
It should be noted that these applications, since they rewrite your system flash memory, can be considered somewhat dangerous.

You can play it safer with Gecko OS, which lets you play import and update-insistent games without altering flash memory. It has been found that at least one game, Prince of Persia: The Forgotten Sands, Gecko fails on.

I'm sure you have tried most of these steps but I'm going to list them any way. So we have a complete picture of the trouble shooting process.

1. Sync system first (by pressing the sync button located next to the SD memory slot)
2. Right after you hit the sync button on the system, hold down the 1 abd 2 buttons on the remote (or press the sync button located under the battery cover).

Try replacing the battery's and or rechargeable battery for the controller. Repeat the sync process above.

Try another controller with your wii or try your controller with a different wii. Repeat sync process above.

If another controller works with your system than that would indicate that there is an issues with your xbox controller.

If your controller works with another wii and no other controllers work with your wii than there is a issue with your console.

If your wii is still under warranty I suggest contacting Nintendo directly.

I hope the info listed above has helped in some way.
If possible please rate this solution.

This usually means the Wii was modified to play other region games and Nintendo has locked it out. In other words, the mod used no longer works and will need removed or replaced.

While holding down the reset button, turn on the power to the Wii. If a menu comes up then your Wii has been modified and won't work again until the mod is removed, assuming if it can be removed.

There is a decent blurb about it here, including instructions for users of Homebrew Channel and Loadmii. I neither use or endorse use of these modifications as it is against Nintendo's AUP/Service Agreement.

Your wii sensor bar probably went out, replace it. They sell wireless ones at wal-mart for $20. If you want to make absolute sure that the bar is broken, take a video camera and take a quick video of the wii bar while it's connected and the wii is on. If you see four little blue lights on each side then you're wii bar is ok, if any are gone it should be replaced. The fact that all the buttons are still working means that your wii is still communicating with remote using bluetooth, but since it's not sensing any motion, it probably means that the problem is sensor bar related.

With all due respect, I am sorry to say that you should only clean what is visible. If it no longer functions, then start looking for the obvious screws to undo. Regrettably, it appears that you may have to replace your unit. You may wish to consider purchasing a silicone cover on this unit (if you get it fixed) or on your new unit.

Good luck, and I'm sorry. I have a three year old, too. I really do understand!

These are actually diagnostic error messages indicating that some functionality within the camera has failed. Therefore the camera needs to be sent in for repair service. You may want to call Olympus Customer Service to discuss their repair process and procedures. Their telephone number is 800-622-6372 option 2 and then option 3.

It is possible that you updated your Wii with a new firmware that was available on one of the game disks. Some modifications do not work anymore after a firmware update. So it might be possible that you have an older modification that Nintendo overrides with a new installed firmware.
It is almost sure that when you remove the modification completely, your Wii is working fine. If so, install a recent modification that is immune for these firmware tricks, dor example the D2Sun

There may be a problem with one of the three cooling fans no longer functioning. There are two fans on the right side (if you are looking in the same direction as the projector is projecting) and one on the left. If even one doesn't function, the unit will too quickly overheat. It must be sent in for repair, in that case.
