Thanks for using FixYa. To start with open the back of the unit and then check the power supply board for any bad (bulged/swollen) capacitors. Power supply board is the board where all the power cords/plugs goes into. You can buy the power supply board from this link. After you have checked that also check the main board and if you can use a multimeter to test the components on these boards. All this should only be done if you have knowledge of internal circuitry of the unit as the components consists high voltages even when in off position.Please do accept the solution if the issue is resolved or post a comment for further assistance.
your TV is having a power problem. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on. Also check the AC outlet to be sure electricity is actually entering into the TV.
If you know about TV repairers, I would suggest that you open the TV and read the power part/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.
