Question about LG Televison & Video
LED TV's have a known problem with capacitors going bad. Without the proper capacitor test all you can do is look for a cracked swollen possible disformed or any burn marks around them to find the bad one to replace best of luck you'll find it

Depending on the model maybe. Tv's like all electronic items use multiple circuits that are interconnected. So if you have a problem like you described it can be any interconnected board. I experienced problems like you described many times. Use your eyes and nose. Turn off the power, remove all boards and visually inspect. While boards are out sniff each board. Look on both sides of each board. If nothing is found I would start with the power supply and replace it. You can check the output voltage where the power supply connects the the main board. It is harder to check the main board function because the signals pulsing thru the main board require specialized equipment.

If the power box is bad, The computer will not come on. if you only get a green light, you would need to start with replaceing the power box, if you get a new one and the same thing happens, then the mother board is bad too.

SOURCE: My Reset button wont reset
Just guessing, here. The reset is actually a "Ground Fault Interrupter" called a GFI. It's there to cut of power in case of a dangerous electrical condition--which you probably don't have.
Did you unplug the unit? If not do so, let the GFI cool for several minutes, and try to reset again. They're pretty hard to push in, maybe use a fingernail, you must hear a click or it's not reset.
Is there water in the outdoor unit, or is it filled with snow? This is the most likely cause of an actual GFI fault.
If the GFI itself has failed (unlikely), you could replace the entire power cord. You should then maintain safety by installing a GFI circuit breaker on that circuit, or you'll be in violation of codes that might affect your homeowners insurance.
There could actually be a problem with the unit. This would be that an electrical wire has come loose and is contacting the metal chassis, creating a shock hazard. Unlikely but possible.
If the receptacal you're plugging into is old and worn it might the problem. Worn receptacles might actually have tiny electrical arcs inside, which can trip a GFI. At a couple of bucks (DIY) it's worth a shot.
If there's actually an electrical fault in the unit it can be found and repaired, but the cost of repair could very well be more than it's worth. Warranty?
