Hi Sharlene, 

May I know how old is the LG Smart TV? Is it flickering now while we are talking?

Do you have the same problem on all sources/inputs? 

Thank for the information  Sharlene . Unfortunately when the issue occurs with any input or sources , this indicates a component failing within the TV that is causing the set to oscillate (flicker).

There's several common failures to look for that will cause the flickering- and there's no quick fixes for it. This problem always gets worse and worse until it finally goes out altogether.

This problem can happen due to several things, and to determine which, a Technician would need to first inspect the Power Supply Board for signs of faulty Capacitors, as well as measure the voltages coming from the Power Supply.

The Power Supply is one of the most common causes of this problem. The capacitors on this board can swell and bulge due to receiving a surge, and can cause a voltage drop on one of the outputs on the PS. This typically will cost you $250+ to have repaired.

The other very common issues, are problems with the other boards failing. They are responsible for producing the image on the LCD /LED display and are the HARDEST working boards in the set. They also incur the greatest amount of heat which can cause failures such as the one you are having. common failures for this type of TV. Average cost for this type of repair is around $400+ parts and labor.

I you will ask me which is more practical. I'll replace TV once it get's worst ( that the filickering is permanent or no display at all)  instead of having it repaired which would cost almost the same price of a new TV with active warranty to cover any problems.
