Had posted an issue back in November with my TCL 65R625 tv freezing upon startup and then rebooting and requiring the plug to be pulled in order to work. It later moved to being at any point using one of the apps or even the TV itself.
TCL replaced the main board on the TV and Roku also updated the software on the TV.
Well, was watching Amazon Prime for a bit this afternoon and then moved to find something on Netflix and the TV stopped accepting input and then rebooted. So it would appear that a new software release is causing issues again.
Now at 9.4.0 Build 4206-88 - Was previously 4200-88.
