This has nothing to do with the power cord, the fault is internal.
This is what happens: a part inside your tv has failed; when the tv is started the first thing that gets powered is the power source; when it reaches working order it starts to deliver the power to the other components, including the failed one; that failed one now acts as a short so the current thru it gets much larger than it should; this huge increase in current is detected by the safety system of the power source which gets triggered in emergency mode and shuts down the power source by force.
Normally the tv's processor would be powered long enough to detect itself the damaged part and generate a fault code - the status light should blink. If this doesn't happens it means that the fault is massive and affects directly the power source. Because of that the tv must be opened and tested, starting with the power source. The first step is something that you could do yourself, just follow this

If, after that, you are still in the same situation, it's clear that another components were also damaged. From now on only an experienced repairman can do the diagnose, you will have to call one.

Hook up to the Wii


Alright so first of all, you should have gotten a cord with a big, grey power brick attached to it. Plug the end in that goes in a outlet, and the other end should hook up to one of the outlets on your Wii console. Then, there should be a cord with three branches. They should be colored red, orange/yellow, and white. On the back/front or on the cable box for your TV there should be plug-ins that are colored either red, white, green, blue, or orange/yellow. The specifications should be written under the outlets (visual, audio, etc...). Plug the white and red part of the cord in to the "audio" outlet (on your tv). The other cord (yellow/orange) should plug in to the outlet that is labeled "video" or "visual" or "screen" or something along the lines of that. The next step is pretty simple. Your Wii (should have) came with a sensor bar. It is thin, long, and black and has a very long, very thin cord attached to it. Plug one side of the cord into your Wii console, and the actual sensor bar goes on top of your TV. There are small, sticky rectangles that help with the sensor bar sticking to your TV. After you've done all that, your Wii is ready to go! Just push the power button and your ready to start playing!

How to wire put on a new plug on a extention cord


If this is a dryer your fooling around with 220 volts and you should not use an extension cord (it can cause a voltage drop and burn out the motor in the dryer or worse a fire) If you can't reach the dryer outlet then you should have the outlet moved to reach the dryer.

Why is the electrical wire so short


Don't add an extention cord to an extention cord! Buy a 100' 14/4 extension cord and tie the end to the fence so it won't come un plugged.
If the plug keeps popping out of the short cord at the blower,wrap the cord around the handle to prevent disconnection.

I have a panasonic plasma tv model TH42pZ80u series i think. as soon as i switch it on all the electricity on my house top floor switches off from the main electricity socket. dont know what to do!


There is a direct short circuit inside the power outlet, or in the mains cord of the TV. Switch off and remove the plug of the TV and just switch on the power outlet to make sure whether that is the culprit. If you have a multimeter, test the TV cord pins for short between phase and neutral and earth. If you notice short, this may need attention by a qualified service technician.

I have a CLT2054 and lost the power cord. I bought a new power cord but when I plug it in the light on cord goes out and TV wont come on. If I un plug cord light comes back on


You have short circuits inside the TV, the AC goes into shutdown when it senses too much current being draw. Post some pictures inside the TV if you can, wee need to look for short circuits, another thing, you bought new AC adapter with the same voltage and current rating, right?

My dryer cconnection is to high for my dryer cord to connect


There is a cpl things that you can do. The best way is to go and buy about 3ft of wire, a plug that fits the outlet, and a receptical that will fit the dryer plug. And make a short 220v extension cord. Or you can get enough wire to replace the other one and a new plug end. Place the plug end on one end of the wire and you will have to get terminal ends like the ones on the cord now. And clamp them on the other end of the wire and install it on the dryer. Make sure that the center wire goes in the center. And the other two dont matter. However if the center wire is at the top on the outlet? Then the black wire goes on right.

I have a clarke 130en mig with gas and it will not weld


The most common problem is that people still try and run the welder with extension cords. 10 ft,25ft,50ft,100ft, these cords all drain and can't supply the energy needed as if you were to plug it straight into a wall outlet. well I don't have a plug outlet where my work is, I need a extention cord. The only solution for not having a handy outlet is a Generator. that will supply the necessary voltage needed to do the job. EXTENSION CORDS ARE A NO NO. also, always double check your ground.

Hope this was helpful, please post a rating good or bad, thank you.

Karcher K3.92 M 1750 PSI poweer Washer motor won't start. Followed Reset/Test/Reset sequence with cord plugged directly into outlet. Light on cord near Reset comes on when Reset pressed down but goes off...


They are sensitive to large extention cords. My father in laws pops reset when a small cord is used. If internally shorted- motor will continually pop the reset even plugged direct to outlet. Check voltage at outlet.
