My Roku TV by TCL just recently began this problem.
It simply stops playing and goes to a black screen after varied amounts of time. Usually it's about 50 minutes.
The TV does not shut off, only black screen not playing anything. If I use the remote and tap the left arrow the guide displays immediately as normal. Selecting the same channel returns me to black screen. Choosing any othe channel shows that channel normally. It will then allow returning to previous channel. After several minutes the problem recurs.
Have done system restart and software update. Have restarted modem and router. I use a wired connection and I have speeds in both directions over 500Mbps.
Any ideas???
Thank you
Same issue. Been driving me crazy. Re-scanned channels, swapped power adapters for my OTA antenna. Almost reset my TV back to defaults but after reading these, pretty convinced a software update has done it. Also on 14.5 version. (14.5.4 ,build 5944) Just watching TV like normal and it just goes to No Signal. Backing out and going to another channel fixes it. Then back to the original channel and it works fine. For a while. Happened about 4-5 times today so far.
