hisense smart tv problem - youtube app

[macbeth]

Hey guys, need some help.

My youtube app on my hisense tv is acting up. I run it on a 20mb/s fibre line that is working perfectly.
However, lately videos have not been playing. The screen freezes/partly pixalates while the audio is fine.
I've phoned Hisense's call centre and they have no idea.
Other devices using the fibre line (dstv) are fine, as is internet, and youtube via wifi in the house.
It is just on the tv that it acts up.
I've checked all settings, and for some strange reason live feeds play fine, but any other video doesnt.
Does anyone have an idea what to do?

Have you tried downloading a wifi channel scanner app to see what's happening? It could be that a neighbour is now running on the same channel as yours causing congestion.

I'm asking because I had the same issue on my samsung smart tv last month. I ended up buying a cheap wifi router placed in direct LOS of the tv and scanned the channels to see which weren't in use. It sorted out the problem.

In my case it was running fine since the start but only gave me issues after I switched off the power to my whole place for 3 weeks when I was away.
