Since my TV received an Android update I had no end of issues. The TV can turn off suddenly while watching normal TV or watching via an app. The sound often does not work and I have to do a full OS restart. The TV goes a funny colour from time to time on the home screen.

The update was received 2-3 months ago. I have been waiting for another update to fix it, but it does not seem like one is coming. 

Should I take the TV back to the shop? I have had it less than a year.
