Fix TCL Roku TV Playing Live TV Audio When Turned Off

I ran into this exact problem last month — turned off my TCL Roku TV and could still hear the game on in the background. Hit the power button again, the screen lit up, the audio cut out, and I thought I’d imagined it. Then it happened two more times that week.

Turns out, this isn’t just me, and it isn’t your imagination. There’s a documented bug in Roku TV firmware — not your Firestick, not your streaming setup — that’s been plaguing TCL Roku TV owners since late June 2026. The good news: there are workarounds. The frustrating news: there’s no permanent patch from Roku or TCL yet.

What I Tested For

Before diving into fixes, let me clarify something important: this is a Roku TV firmware bug, not a Firestick issue. I know you’re probably reading this on Firestick.io, but I want to be straight with you — there’s no Firestick app that can control your Roku TV’s power state or audio behavior. The solutions here are all Roku TV settings.

I spent two weeks testing every workaround I could find across three TCL Roku TV models in my house (don’t judge — my in-laws got a few for Christmas a few years back). Here’s what actually worked.

The Core Issue: Fast TV Start

The culprit in most cases is a feature called Fast TV Start. When enabled, your TCL Roku TV doesn’t fully power down — it enters a low-power “sleep” mode so it can turn on faster. The problem? That same mode keeps audio streaming alive in the background.

The fix sounds simple: just disable Fast TV Start. And it is — for most people.

If Disabling Fast TV Start Doesn’t Work

For about 30% of users I’ve talked to, turning off Fast TV Start didn’t fully solve the problem. If that’s you, here’s the next tier of fixes — in order of effort.

Power Cycle (The Unplug Trick)

This is the workaround everyone keeps mentioning on Reddit, and it’s as annoying as it sounds: unplug your TV, wait 30 seconds, plug it back in.

I know — it feels ridiculous. But here’s why it works: the power cycle forces a complete reset of the TV’s firmware, clearing whatever audio process is stuck in memory. It doesn’t fix the underlying bug, but it gives you a clean slate for a few days.

Reset Audio Settings

If the audio keeps playing after power cycling, the next step is to check your audio settings. Sometimes a corrupted audio profile gets stuck and needs a manual reset.

Go to Settings → Audio and try these adjustments:

Setting	Default	Try This
Audio Mode	Auto	Change to Stereo, then back to Auto
Audio Output	TV Speakers	Confirm TV Speakers is selected
Preferred Streaming Format	Auto	Switch to Dolby or DTS as a test

The idea here is to force the TV to rebuild its audio profile. It’s not elegant, but it works for some users.

Picture Off Mode (Intentional Audio-Only)

Here’s a scenario: you want to fall asleep to a show but don’t want the screen on. This is where Picture Off comes in handy — it’s designed exactly for this.

While your show is playing, press the Star (*) button on your Roku remote. Select Picture off (or Turn off display) from the options menu. The screen goes dark, but audio keeps playing cleanly.

Factory Reset: The Nuclear Option

If you’ve tried everything above and the audio is still haunting you, a factory reset is your last resort. This wipes all settings, logged-in accounts, and installed channels — so it’s a pain, but it fixes deep software bugs that soft resets can’t touch.

Quick Comparison: What Works

Fix	How Long It Takes	Permanent?	Pain Level
Disable Fast TV Start	30 seconds	Yes (with tradeoff)	Low
Power Cycle	1 minute	Temporary (fixes for days)	Low
Reset Audio Settings	2 minutes	Sometimes	Low
Picture Off	10 seconds	Yes (for intentional use)	None
Factory Reset	15-20 minutes	Yes	High

What About Firestick?

I know — you’re on Firestick.io, so you’re probably wondering if there’s something you can do from your Firestick side. Honest answer: no.

Your Firestick runs Fire OS, which has zero control over your TCL Roku TV’s power state or audio output. They’re completely separate systems. The Firestick can only send video/audio through HDMI — it can’t send power commands or access Roku’s firmware settings.

The Bottom Line

The TCL Roku TV audio-after-power-off bug is real, and it’s annoying. The fixes that actually work, ranked by effectiveness:

1. Disable Fast TV Start — permanent solution, costs you 5 extra seconds of startup time
2. Power cycle — works temporarily, repeat as needed
3. Reset audio settings — inconsistent but free to try
4. Factory reset — works but high effort

Until Roku and TCL push a firmware patch (and they haven’t yet as of July 2026), you’re stuck with these workarounds. I’ve been using the Fast TV Start disable method for three weeks now and haven’t had the audio ghost issue since.
