The backlight controller is faulty. It will need to be repaired or replaced. The cost of the repair depends on the exact nature of the fault. It may as simple as replacing some capacitors, or it may require new inverter transformers or the whole board may need replacing. Get a quote from a TV repair shop.

What model of DVD player do you have? The RF cable jacks on dvd players are only for switching the RF. All players always use AV input/output or Component input/output, the later is the best.
