Question about Televison & Video
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. The inverter is the power supply source for the backlights. If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. 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.
