Hello Billy, if everything is fine, except for the video that does not have the function of rf if I send a signal through the audio and video input I have image and sound. When I put it on rf I have sound, it changes the channel, I have a menu on the screen but I don't have a video. I was watching the forum and a colleague said that he had to rewrite a memory but I don't know how it is done in the case of TV LEDs. I have recently repaired this type of TV, I dedicate myself mostly to conventional equipment with cathode ray tube.
