Re: [Solved] Black screen on Live Antenna Channels?

This issue seemed to appear right around the time of the latest software update on my TCL 43" TV;

Software version: 14.6.4

Build: 9911

Updated 6/20/25 at 3:35 pm

This happens while watching OTA/antenna broadcast channels via the "Live TV" channel guide (with the streaming channels disabled/hidden via system settings);

At the end of each and every show being watched, the broadcast signal is seemingly "lost" - the screen goes blank/black, with no audio or video. This happens exactly at the very minute the program ends; if, say, it's a 1 hour show from 9:30 to 10:30, it'll happen exactly at 10:30 (plus a few seconds). If a half-hour show - say from 2:00 until 2:30 - it'll happen at exactly 2:30 (plus a few seconds).

This occurs every time (every half-hour/hour), regardless of channel number and regardless of network being watched. If left alone (blank screen) for a few minutes, the screensaver will show up (floating analog clock, in my case).

Switching to another channel and back again revives the lost broadcast channel, until the next half-hour/hour comes around and the TV just quietly goes completely blank, yet again. Over, and over, and over, and... 😠

Needless to say, this is a significant, pronounced and incredibly irritating bug.

I have restarted/rebooted the TV numerous times via System Settings and the normal power button, cleared the cache (press Home 5 times, Up 1 time, etc.), checked for updates - to no avail.

My wild guess is that a network-interrupting software bug was likely introduced as a result of changes attempting to;

a) implement telemetry that attempts to determine what OTA programming we're watching, or...

b) determine what commercials are being broadcast between OTA programs/during commercial breaks, or...

c) determine when to update Roku's own pushed channel guide advertisements/favorites/etc banner, or...

d) Roku is attempting to "break in" to OTA broadcast TV's advertisements, disable/override them, and insert their own ads (likely very illegal and definitely underhanded, if so - but I wouldn't put it past 'em).
