My Sony Android Smart TV occasionally freezes and reboots- Why?

[MrHT]

I have a Sony XBR-43X800E 4K TV and had it for about three years. For the first couple of years, I never had any issues with it except for the smart TV being rather sluggish, so I ended up buying an Apple TV streaming device for better streaming performance. But when I bought the Apple TV, I still kept the TV connected to the internet in case I needed the Smart TV for backup or in case there are firmware updates. Well, around the summer of last year, the TV started occasionally freezing whenever I turn on the TV and then would reboot on its own. It would act up and do that maybe around once a month. So what I decided to finally do was reformat the TV and do a factory reset. I did that and kept my TV disconnected from the internet and did all my streaming exclusively from the Apple TV box. After doing that, I didn't have any freezing/rebooting for MONTHS. So I was like, maybe the factory reset did the trick! Well, last week, I decided to connect my TV to the internet to check to see if there were any firmware updates. There weren't any, so I shut off the connection to the internet thereafter. Well, today while I was watching a Blu-ray, the TV just randomly shut off while I was watching the movie and then rebooted. So here we are back to the freezing/rebooting issue again.

I really wonder if my connecting the TV to the internet last week triggered something on my TV and it's now causing it to glitch up again. So I went ahead and did a factory reset today and will try to keep the TV disconnect from the internet forever, assuming that is even causing the issue. But I will keep my fingers crossed that this will do the trick.

So does anyone know what could be causing my TV to randomly freeze and reboot occasionally like that? Is it possible that connecting the TV to the internet is making the TV install some bloatware that's causing the firmware to glitch and make it freeze and reboot?
