Hello, I have been having trouble trying to open my Samsung TV and my remote is broken and my backup button located on the bottom of the TV is also broken, and I tried an external remote like downloading a remote app and using that but now it isn't working and I can't check my TV for any problems because my TV isn't opening, I am confused and stuck on how to open the TV, I need some assistance please.

I also tried unplugging the TV cable but for some reason it also won't turn on, probably because my TV needs to be on to do that.

My Samsung TV model is UN58RN7100FXZA

Please let me know if you need anything else from me to answer.
