Hello, you need to make sure what is broken, the remote control or the TV. To check the integrity of the remote control, you need to broadcast from the remote control while he aimed at the video camera. If you see a flicker of light through the camera it shows the integrity of the remote control. In this case the infrared receptor need to be replaced, he is placed near the stand by light.in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility that something is wrong at the microprocessor circuit. . If the remote control out of order, can be opened carefully by a thin screwdriver, usually the causes to the error are loose components or contacts that are supposed to weld back into the board.
i hope it was helpful!! Let me know if you need further guidance
