Check all inputs connections is all I can suggest, if all is ok and all video source inputs do this the TV has a failing circuit board.

Several possibilities but most common seems to be power supply defect or poor connection. Check these resources. Note that other Youtubes that may address the problem are also accessible from the youtube link.

42 inch LG LCD tv, mounted over a radiator?

electronics do not like heat and and heater works by rising hot air
in your case that hot air will go straight up into the electronics which will result in problems
a wide shelf under the tv will be a good idea as that will stop excess hot air straight up into the tv

42 inch LG Plasma TV - Lost picture

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Try what they suggested. The attenuator may block some signal that is causing the difficulty with your set. And it is installed on only the line going to your set and not the main line coming into the house.

I have a LG 50 LCD TV Model: 50LN5700-UH that has a black screen. There are a couple of things I have tested and replaced. First off there is audio but just a black screen. I turned off the lights and looked for signs of back lights. When I did this there were no visible signs of lights. In addition, I did the flashlight test. Which showed visible signs of lettering on the screen with the flashlight. Which if I understand correctly it may determine that the T-Con board is functional. I ordered additional LCD's from Shop Jimmy and replaced the bad sticks. About half were replaced. I reassembled the TV and I am still getting no video, but I still have audio. However, this time all the LCD's are functioning so now the screen is still more grey than black because of the working LCD's I replaced. What voltages and at what points should I be testing to narrow down the problem, or what other problem-solving technique should I be testing? One other thing I should mention is there no visible signs of swollen capacitors or any signs of burn marks. I am 99% sure I connected all of the cabling up correctly, not 100% since this was my first attempt but I am a little less confident I put the filters in the correct way. I had the TV disassembled while I was waiting on the LCD's to ship and when I re-assembled I was less confident if I picked up all 3 or 4 filters and set them down, or if I make have flipped the filters to keep the circuit board on the front cover from being damaged. Hope that make since.
