Good Day guys

I hope I am posting in the correct place.

I have an Xbox one, using a LG 55inch smart tv. I did not use my console for about a month, when I tried using it today, the console comes on, the controller comes on, but the tv cannot pick up signal from the console. When I click on the hdmi port which i have the console connected to, it just says no signal. I have swopped around ports, tried different hdmi cables, but no luck. I googled the issue and see its quite a common issue on the Xbox one console, but most of the guys who experienced this fixed it by doing reboots and unplugging etc. I have tried all of that, but still no luck.

Just wanted to know if anyone here experienced that, and if so, how did they fix it.
