This is Usually caused by bad capacitors, open the TV up and check the power board to see if there are some visually bad capacitors. if nothing looks off you could test the capacitors with a multimeter. You can replace the bad ones or you can replace the whole board. most tv’s have three boards there will be a TCON, mainboard and a power supply. sometimes the mainboard and power supply are together.
