In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

remove the power cord from the wii. hold the power button in for 15 seconds.
plug the power back in. if the power light comes on check the color.
green is on, yellow is standby and red is totally off.

if there is a light press the power button and see if it turns on. if it does not then from a Wiimote, press and hold the power button on the remote. this should turn the console on. if the console does not turn on and the remote batteries are good you can try one more thing IF the light is on.

press and hold the reset button for 10 seconds on the system. disconnect power and replug. if you still cannot turn it on then your system is bricked or damaged and needs replacement.

in any case the power button is broken you can turn the console on and off from any remote

Tries unplug,replug the tv about hour later,let the tv resetting itself back to factory setting.The tv should work now.Not,than the power supply board have problems,that the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hi,

Sounds like there is a short on the power board or the power board has gone faulty.

You will need to seek out an engineer.

Thanks

unit seems to go into protect mode.Theres very little that can be done..There is good chance unit needs to be checked at a repair shop.Try to find one that is authorized for your particular brand if possible

I have the same issue. Here's a temporary solution, which is what I've been doing for the last couple of weeks, unplug the unit from the wall, just long enough for the red standby light to go out, then plug the unit back up. as soon that the red standby light comes on, press the on button the the remote or the unit. You may have to do this couple of time before it works. Somedays it works on the first try for me and then somedays I have to do it 3 to 4 time. I sure that at some point this will stop working too.

Mine was doing that and I ordered a replacement power supply board for it and now it work. It's fairly easy to replace.

turn the power on. to get rid of the red light you need to press the timer/rec button on the remote until it turns off. the red light means it is programed to record.

This set has a modification that needs to be done. It will also start turning on by itself and changing channels rapidly. It's two weeks old. Take it back to the Retailer or if that is not an option contact LG at 1-800-243-0000 to get a local servicer in your area.
