For a few months now my HDMI stopped working, I used it frequently to play some games in N64 emulator, but one day, out of nowhere, I didn't give video on my TV again. I tried the cable on another device and it didn't work anymore, so I bought another one, but now when I connect the laptop to the TV with this new cable, the laptop screen turns off, and the TV doesn't show anything either. Anyone have any idea how to fix it? My laptop is an HP 15 Notebook PC with an AMD E1 2100 processor and the integrated one is a Radeon HD8210, I hope someone can help me.
