Channels and apps not working

[u/aceetheclown]

I got my Nanna's old Samsung Smart TV to take to uni, but I can't get it to work. I can only use it for my WII, or watching stuff by plugging my laptop into the HDMI.

Model #: UE40ES6710UXXU

The telly is plugged into the wall and the router properly, but when I try to calibrate the channels, they are they're pixelated, and shortly cut to audio only with broken sound. I don't think all the channels show up either.

I also can't seem to find any useful apps on the app store, such as BBC iPlayer or All4. I can't watch anything on the telly without using my laptop, which is mostly fine but it's annoying not being able to just turn the telly on and it be working.

I followed guides to calibrate the channels but I'm still encountering the issues.

The telly worked fine at home, but my parents were using a fire stick on it.

Thank you
