All hdmi ports stopped working on my ONN 70in tv. The tv knows a device is plugged into the port but says it’s not powered on when trying to view it. Have tried different cables and different ports with the same results. Plug the device into another tv and it works fine. It has recently started showing an overheating error around the same time the hdmi ports stopped working. Left it unplugged overnight and the overheating errors stopped but the hdmi ports still don’t work.
