OK its a bad main-board, this board will need to be replaced do you think you can do that work yourself?If the set has warranty please use it, usually 12 months but could be 3 years.
You need to get the back off the set, locate the main-board that's the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the part-number google the part-number to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play)
Let me know if you need more info either now or later, I am sorry this is not something easier, the set has developed a problem that needs to be addressed.

If you require more help please let me know, if you have no warranty with the set then outside of a do-it-yourself repair to the set you will need a technician, I would be happy to help you if you can do this yourself...
Please let me know which way you want to go with this thank you
