If you are able to get power to come back on, but then it keeps going out, the problem is likely due to either overheating or from an unlicensed accessory tripping the fuse on the AC Adapter. Please check for the following:

1 - Make sure that the word "Wii" and the model number "RVL-002 (USA)" molded into the AC adapter. Unlicensed products are not fully compatible and may not work correctly.
2 - Avoid the use of unlicensed products such as memory cards, controllers, and cheat devices. Some of these products are poorly manufactured and may result in damage to your system. If one of these products is attached to your system, remove it and try resetting the AC Adapter (see below).
3 - Check all accessories, licensed or not, for phsyical damage. Physical damage, such as frayed wiring or a cracked housing can cause the system to shut down. Remove any damaged products and try resetting the AC Adapter (see below).
4 - Make sure the Wii has good ventilation. Avoid operating the Wii while it's on carpeting or inside an enclosed space. If you have the Wii placed in a vertical position, make sure the vents on the bottom are lined up properly with the hole in the plastic stand and no foreign material is obstructing that hole.
5 - Check the vent on the back and side (or bottom, depending on how you have the system positioned) of the Wii for dust build up. The system will shut down if it cannot vent properly to prevent overheating. If there is a build-up, remove it using a vaccum cleaner with a soft brush attachment.
6 - If the above steps do not solve the problem, you should try resetting the AC Adapter. Click here for instructions on how to do this.

resetting the AC adapter.

1 - Unplug/remove all accessories from the system (including game discs, SD Cards, memory cards, Nintendo GameCube controllers, hookup cables, the AC Adapter, and Sensor Bar) from the outlet and Wii.
2 - Let the system rest for about 90 seconds. While you're waiting, check to see that controller cords, AC Adapter, and Stereo AV cables/Component Video cables are not frayed or have exposed wires (this can cause the system to shut off); if so, you should replace those parts.
3 - After the 90 seconds, Plug the AC Adapter into the system and wall outlet. Check to see if the power light on the Power button comes on.

- If the system works, plug ONE accessory into your system starting with the Sensor Bar, then turn the system on to see if it still works. Repeat this process with ONE accessory at a time. If your system doesn't work once you put a particular accessory in (Sensor Bar, GameDisc, Nintendo GameCube controller, Memory Card, SD Card, etc.), there may be something defective with that accessory.
- If the power does not come on, a repair will be necessary. Because it is not possible to determine which item (Wii console or A/C Adapter) needs repair, please call our Consumer Service Department at 1-800-255-3700 to discuss available options, or click here to e-mail us.

I was pretty impressed with Netflix on the Wii, but at least on my TV the 360 SD looks better. Overall though I was very happy. I may put the Wii in my daughters room so she can stream shows she wants to watch.
