Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

The flashing indicator is telling you the fault. Give the number of flashes to the LG service department and they can help you with your issue. It will likely need service.

Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.
Have it checked by a technician if you cannot do the work.
