I have a brand new LG 26LD350 that won't power on. It's not my outlet, I checked it with another appliance. Could it be something as simple as a bad power cord?

bad power board or bad screen

Replace the power supply or at the very least check for swollen capacitors on the power supply

Hello

Plug the microwave into the outlet if the microwave won't power up. Make sure the plugs on the microwave match the type of outlet. A four-pronged outlet can only be used with a four-pronged plug. Same with three-pronged outlets---they only work with three-pronged plugs.


Inspect the plug. Make sure it hasn't been cut or tampered with. Four-pronged plugs can't be cut down to fit a three-pronged outlet. Three-pronged plugs mustn't be forced into four-pronged outlets. A three-pronged plug mustn't be used in a two-pronged outlet, either.


Replace blown fuses, or if there's a circuit breaker, check it for tripped breakers. Sometimes the trip won't be obvious, so cycle the circuit breakers. Turn them all the way off and then back on again.


Plug another appliance in the outlet. You will find this easier with three-pronged appliances. Simply plug a toaster, or other appliance into the microwave's outlet, and see if it works. If it works, you know the problem is with the microwave, not the power circuit. Have the microwave serviced or replace it. If the toaster or other appliance doesn't turn on, you know the problem is with the circuit.

Yes,the power supply board have a fuse near the edge of the board.That the board,where the power a/c cord plug into it.

sounds like a faulty lcd panel but you will be suprised how many we used to get back where it was something simple like the wires not being connected to the power supply for the screen. the lcd panel is very expensive to replace, nearly as much as the tv itself.

I have never heard of any LG TVs having a fire issue.
LG added this switch to help save electricity. "Going Green".
You see, this On/Off switch was added to kill the power to the TV when not in use. This switch stops the TV from consuming power by not giving it power to be in a “Stand-By” mode.
If your TV does not have this switch, you could simply unplug your TV to give you the added satisfaction it won’t catch fire.
I hope this information has helped.
Good Luck.

if won´t power on manually or using remote control, may be you have an power supply or horizontal output trouble, first check that your outlet is powered with something, use an radio for example.

First, there is an outlet. Plug in something else. Inside the key panel, there are fuses and a thermo sensor. Either may be bad. The thermosensor is about the diameter of a dime, black and 3/8 inch thick...attached to the wall of the chamber. All should have continuity.
