Re: Roku tv not showing the thumbnail pictures
I think it's a bug too. Last night when I switched from antenna I got the background screen on the home screen and no icons at all. I went back to antenna and it was just a blank screen. I finally had to unplug it and everything came back afterwards. This is really annoying and TCL is no help at all. I'll never by another tv of there's again!
I will occasionally see the same issue with Prime Video on my 32" S-Series TCL Roku TV. Others have mentioned deleting apps to save some memory resources, but I have 60+ apps on my S-Series and it only happens rarely and only with the Prime Video app. When it does occur I find that doing a RESTART will correct the issue. SETTINGS -- SYSTEM -- POWER -- SYSTEM RESTART -- RESTART. The same as pulling the plug, but you just need your remote to get it accomplished. Probably not a bad idea to just perform a RESTART/REBOOT of this older device weekly to clear out any cobwebs that build up. I still think this is a Prime VIdeo / Roku OS bug more than deleting a large portion of the apps you have installed.
