Phone LG and ask them if your set is eligible for a firmware upgrade.

Our LG TV will not power on. No light, no sound, nothing. How can we check the fuse on the power supply? Or could it be the power cord?

Hi Dfhamilton,
Damages due to lightening surge can go to any extent in a tv set. If you can, please open the back cover and check the fuse. Replace with the same rating one if you find it blown. Switch on the set. If it works, enjoy watching. If it blows again, please consult some TV tech.
Good Luck.

Had an electricity power cut during the night. Next morning, tv had no lights on it at all and won't switch on. Checked fuse, power lead etc?

sounds like you have had a brown out or a surge they go strait pass the fuse and fry almost all the electronics in the unit. due to the damage that occurs we do not fix these units we write them off as respect to our customers. some techs fix them but they never last. far to much damage. but there is good news all insurance companys cover surge damage if your not insured and even if you are if you have suffered a surge/ or brownout then your electricity provider must replace the unit damaged. and from now on always use power boards with surge protectors in them they cost about $ 9 and cost far less than a $ 1000 tv

best of luck to you

Hi LG help guy, I have an LG plasma TV 50PG25, same as the 50PG20 by the look of it. Recently my wife and I went on vacation and as we usually do, unplug major electronics (PC, TV, etc.). When we...

No LED light at the front means bad power supply most of the time (not always though; rarely it may also mean bad main board or at least the portion of it responsible for the standby operations).

This is easy to happen as a result of a power surge, for example.

You can try searching here:

Or you can go to and search there as well.

Hope this helps!

Does Turning an LCD TV on and off repeatedly damage it? I have been doing this to mine quite often, and am worried that I am causing damage to it.

There are about 4 main power supplies in the TV, standby 5vdc (always on and running 24/7 the second the TV is plug into the wall outlet), the other 3 are switched on when you hit the power switch on the TV or on the remote, every time you power it on the power supplies will see current surge when it turn on, which can stress the components, not much you can do, if the TV was design correctly to take the current surge into account then it should have no problem, but so far I have not seen really well made TV any more, does not matter the brand, youcan see that at FIXYA with all the problems everyone has with the TV's.

An electrical pulse from the thunderstorm has affected your TV. (Was it on a surge protector?)

There is a small possibility that it will come back.

Unplug the television and let it sit for an hour or more and then re-plug it.

If you need to get a new TV, also get a good surge protector such as Panamax.

The tv stopped working. Can't get power to turn on.

i think your unit suffered what we call a surge happens when sudden power out and on of the electricity.a large amount of current is flowing instantly when the power came back,like units which permanently plugged-in suffers.especially the tv if you can open your unit and check for blown-out fuse or any related incident you can find in your unit.its best to have a tech's help for that.i'm sure there is a defective part/parts in your unit.

Protron 42

on the back of the TV where the power cord plugs into the back of the tv there is a small black on/off switch- it's not as obvious as you would think.... but that was turned off. Not sure how that happened since the back of the Tv was never touched when it went dead- but I unplugged the cord from the back of the tv and from the outlet and reset that switch and it worked.

LG 47" LCD TV - 47LC7DF Clicking Noise

I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?
