I am having issues with some apps not opening (showing a black screen) or not connecting to the network. When I switch over and use a Roku stick the TV works great. It is showing the TV has not been updated since May 12. Is it common to have it that long between updates. I have already manually tried updating it with no change to the date.
Have you tried resetting your TV to its factory settings? That may help resolve any software-related issues. Regarding the software update, it's not uncommon for TVs to go a few months between updates. However, if you're experiencing issues, it may be worth reaching out to the TV manufacturer's customer support to see if there are any known issues or if they can provide further assistance.
