Today when my wife went to turn our TV on. The TV was giving off sound but no video. I tried my Xbox which is on HDMI 2, same problem. I then tried the DVD player which uses composite cables and all works fine. I then use the TVs remote to access my apps and they all work as well. It seems like any HDMI port on the TV will give off sound but no picture. I’ve tried swapping wires and turning off the tv for a few minutes then back on with no luck. The TV is less than a month old. Does anyone have any suggestions?
Edit: we’ve went into the settings and saw the backlight set to 0 for some reason. I raised it and still no video when I went to HDMI 1. However, when I hit the home button the HDMI1 picture flashes for a split second before switching to the Home Screen.
Contact the retailer, sounds like a mainboard if HDMI not working . Are the HDMi connectors loose on the board, cable wiggle about? If u do a factory reset ,and shine a torch on the screen ,can u see anything? That could indicate the panels gone .
