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 need to fix the circuit of the infrared receptor. 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 assistance.
