I have three ROKU tvs. In the last couple of months I've been having guide issues. Two are TCL and one is Insignia. The problem is that when I power them on the guide no longer works. If I try to use it I wind up looking at 4ish rows of grey but 0 text. Sometimes I can see the guide but not the channel data. The only thing that works to fix it is to run another channel re-scan. After that I can see all programming guide info and the channel info and all is well. The next day I power the TV on and boom... nothing but 4ish rows of grey. Have any of you had this happen and do you have a workaround that is permanent? My workaround works but it sucks.
Can you please provide us the following information:
-Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About)
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
-steps to reproduce the issue you are seeing
Once we have this information we will be able to pass it along to the appropriate team to investigate further.
