you will have to remove the back of your TV and check the main board. That is the board that has all the inputs on it. It does sound like you possibly have a shorted component on that in the HDMI circuitry. Post some good pictures of that boards with your question. that will allow us to see what you see Agregar imágenes a una pregunta existente

We need to know the exact make and model of your TV to determine if schematics etc. are available.
