Question about LG Televison & Video
This sounds like you have a known issue with the power supply board. The power supply is seeing a problem (typically with the 5vdc) and will shut down the TV just after you try to turn it on.
If you keep trying to turn on the TV, eventually you will catch the 5vdc circuit working and the TV will work until you turn it off.
Soon, the power supply will fail to where the TV will not come back on.
The power supply is around $160 and up. I can find your part number if you give me the rest of the numbers after the model number (example "A.SUSLLJR").
Or, you can have someone in your area fix you TV.
Good luck. I hope my information has helped you.
