TV reset not helping — factory reset failed, boot loop, black screen, Wi-Fi & app fixes

Technician avatar Technician
Hey! We’ll fix the TV reset not helping problem fast — and the key is this: a factory reset wipes settings, but it does not always fix issues caused by power glitches, firmware corruption, HDMI-CEC/eARC conflicts, or a Wi-Fi/DNS problem. That’s why people get stuck in a loop: “I reset it… and nothing changed.”

Quick questions so we choose the right path (and avoid repeating the same reset):
• What TV brand/model and OS: LG webOS, Samsung Tizen, Sony/Google TV, Android TV, Roku TV, etc.?
• What exactly happens after the reset: stuck on logo, keeps restarting (boot loop), black screen with backlight, “no signal,” or it turns on but apps won’t load?
• What reset did you try: “Restart” from menu, power cycle, reset to initial settings, or a hidden hard reset / recovery screen? Any PIN issues?
• What’s connected: soundbar via HDMI eARC, game console, set-top box, Roku/Fire TV/Apple TV, or a receiver? (HDMI devices can cause reboot loops via CEC.)
• Any recent change: software update, power outage, new router, new HDMI cable, moved outlets, storage almost full?

Reply with that and I’ll give you a step-by-step complete recovery checklist you can do at home.

It’s an LG Smart TV (webOS). I did “Reset to Initial Settings” because apps were freezing and the TV was acting weird. After the factory reset, it’s still bad — sometimes the TV restarts randomly, and sometimes it powers on to the logo and then goes to a black screen. When it does load, a bunch of apps are missing until I sign in, and the Wi-Fi won’t connect consistently. So yeah: reset not fixing the main problems.
Technician avatar Technician
That combo is classic: boot issues (logo → black screen / reboot loop) + network instability after reset. The reset removed your settings, but the TV can still be fighting one of these:

• Power-state glitch after an outage or quick unplug — the TV needs a true power reset (not just “restart”).
• HDMI handshake / CEC / eARC conflict (soundbar/receiver/console) that triggers reboots or black screen.
• Software/firmware issue that requires an update (or re-install) — resetting doesn’t repair damaged firmware.
• Wi-Fi/DNS problems: after a reset, the TV re-checks region/time/account, and flaky DNS/DHCP can look like “the TV is broken.”

We’ll do this in a fast ladder: (1) eliminate power/HDMI causes, (2) stabilize Wi-Fi + time/region, (3) refresh the TV software path, and only then consider deeper recovery steps.
Customer
What should I do first that actually changes something? I already did the factory reset twice and it feels like I’m just wiping settings over and over. Also I do have a soundbar on HDMI eARC and a PlayStation connected. Could that really cause the TV to restart or go black?
Technician avatar Technician
Yes — HDMI-CEC and eARC can absolutely cause boot loops, random restarts, and “logo then black screen,” because the TV is negotiating control + audio + video at startup. Let’s do the quickest “prove it” test.

Step 1 — True power reset (fixes stuck power-state bugs)
1) Unplug the TV from the wall (not just the remote).
2) While unplugged, press and hold the TV’s physical Power button for 15–20 seconds (this drains residual power).
3) Wait 2 minutes, then plug back in and turn it on.

Step 2 — Boot test with “zero HDMI” (isolates CEC/eARC conflicts)
1) Unplug all HDMI cables (soundbar eARC, console, streaming box).
2) Turn the TV on with nothing connected and see if it still restarts or goes black.
3) If it’s stable, reconnect one device at a time (start with a simple device, save the soundbar for last).

This takes 5 minutes and tells us if the reset “didn’t help” because the real cause is HDMI/CEC, not settings.
Customer
I did the power drain + unplugged all HDMI. The TV actually stayed on longer and didn’t restart immediately. When I reconnect the soundbar to eARC, the black screen comes back sometimes. With just the console, it’s mostly fine. So it looks like the soundbar/CEC situation is a big part of it. But I still have the Wi-Fi not connecting problem and apps acting weird after reset.
Technician avatar Technician
Great — we found a real culprit. Now we’ll lock in a stable setup so the TV reset not helping story ends for good.

Step 3 — Fix HDMI-CEC/eARC without giving up your soundbar
1) On the TV: turn off SIMPLINK (HDMI-CEC) temporarily (name may vary, but it’s the HDMI device control feature). Test stability.
2) Leave the soundbar connected, but switch audio output carefully: try eARC on/off if your TV menu has that toggle. Some combos are stable with ARC but glitch with eARC.
3) If the soundbar has firmware updates (via its app), update it — a soundbar bug can look like a TV issue.
4) If you need CEC for convenience, re-enable it after stability is confirmed and keep only one “control device” if possible (sometimes multiple devices fighting for CEC causes the reboot/black screen).

Now, for the Wi-Fi won’t connect + app weirdness after reset: that’s usually a network handshake/DNS/time issue, not a reason to reset again.
Customer
Turning off SIMPLINK helped a lot. The TV stops doing the black screen thing with the soundbar. So that’s a win. But Wi-Fi still fails: it sees my network, then says it can’t connect or it connects with “no internet.” After reset I also noticed the TV time/date was wrong until it synced, and the app store was empty until I signed in. What’s the fastest fix for this smart TV Wi-Fi problem?
Technician avatar Technician
You just named the biggest clues: wrong time/date and “connects but no internet.” That’s often DNS/DHCP or router security, not a broken TV.

Step 4 — Fast Wi-Fi recovery (works after factory reset)
1) On the TV: Forget network (remove saved Wi-Fi), restart the TV, then reconnect fresh.
2) Reboot the router (quick power cycle) and confirm the Wi-Fi password is correct (after reset, one wrong character = endless “can’t connect”).
3) If your router has both bands, try the other one: 2.4 GHz is more stable at distance; 5 GHz is faster but weaker through walls.
4) Check router security: if it’s set to “WPA3 only,” switch to WPA2/WPA3 mixed for compatibility (some TVs struggle on WPA3-only).
5) If the TV has manual DNS settings: set DNS to a known public DNS (this helps when ISP DNS is flaky). Then test app loading and store sign-in again.

Step 5 — Fix “apps missing” after reset (normal but easy)
After a reset, many Smart TVs show fewer apps until you complete: region, terms, account sign-in, and time sync. Once Wi-Fi is stable, sign in and let it sit for a few minutes to repopulate the content store.
Customer
Switching the router to WPA2/WPA3 mixed helped, and Wi-Fi connects more consistently now. Apps are mostly back after I signed in. But I still get occasional slowdowns and sometimes the TV feels “laggy” even after the factory reset. Is there anything else to do at home besides resetting again?
Technician avatar Technician
Absolutely — repeating a factory reset is usually the slowest path. “Laggy after reset” often means software update pending, storage pressure, or a background process still rebuilding indexes after sign-in.

Step 6 — Make the TV fast again (without another reset)
1) Check for a software/firmware update and install it (TV updates often include stability fixes for reboots, Wi-Fi, and app crashes).
2) Remove apps you don’t use, and disable auto-start features that keep apps running in the background.
3) Power cycle once after updates (yes, again) — updates can leave services in a half-restarted state.
4) If you use an external streaming box (Roku/Fire TV/Apple TV), try it for a day: if everything is smooth there, the TV panel is fine and the issue is mainly the internal smart platform. That’s a valid “fast fix” many people use.

If you still see freezes + random restarts after we already fixed CEC/eARC and Wi-Fi, then we look at a deeper software recovery step.
Customer
I updated the TV software and removed some apps. It’s definitely better. But I’m worried: if it ever gets stuck on the logo again, what should I do first? I don’t want to jump straight to factory reset and lose everything.
Technician avatar Technician
Smart approach. Here’s the reset ladder I recommend when a TV is stuck on logo or a reset “didn’t help.” Do these in order:

First (fast, no data loss)
• Do a true power reset (unplug + hold power).
• Boot with all HDMI unplugged (CEC/eARC can hard-break startup).
• If the remote is acting up, replace batteries and test the TV’s physical buttons — remote pairing issues can look like a “frozen TV.”

Second (fix the common return-of-the-problem)
• Turn off HDMI-CEC/SIMPLINK temporarily and reconnect devices one-by-one.
• Verify network basics: router reboot, WPA2/WPA3 mixed, and stable DNS.

Third (only if needed)
• Update firmware. If the TV can’t update online, use the manufacturer’s USB update method (this is often the real fix when factory reset fails).

Factory reset is helpful when the settings database is corrupted, but it’s not the universal fix — you proved that already.
Customer
That makes sense. One more: if the TV ever shows a recovery screen or “Android recovery” type menu (I’ve seen that on another TV), is that dangerous? I’m scared of pressing the wrong thing.
Technician avatar Technician
Good caution. On Android TV / Google TV, a recovery screen usually appears after a failed boot or update. The safest move is: don’t “explore” — follow a known-good path.

Safe rule: if you see recovery options, start with non-destructive steps (reboot/power reset). If the device is stuck in a loop and normal boot never works, then a guided recovery reset can be appropriate — but it should be done carefully and ideally with step-by-step help so you don’t wipe more than necessary.

For LG webOS you typically won’t see Android recovery, but the principle is the same: use power reset + HDMI isolation + update path before you do another full reset.
Customer
Got it. After doing the power reset, unplugging HDMI devices, turning off SIMPLINK for the soundbar, fixing Wi-Fi security, and updating the TV software, the TV reset not helping situation is basically solved. Thank you — this was way faster than resetting again.
Technician avatar Technician
Summary: when a TV reset is not helping, it usually means the root cause isn’t “settings.” The big fixes are: do a true power reset, isolate HDMI-CEC/eARC conflicts (especially with soundbars), stabilize Wi-Fi/DNS and time/region sign-in after reset, and install the latest firmware update.

If you want, Open the chat and tell me your exact LG model + soundbar model — I’ll give you a clean “known-good” setup (CEC/eARC + audio output + network settings) so it stays stable.

Quick answer: the accepted fix

Accepted first fix for TV reset not helping: stop repeating factory reset and diagnose the real cause. Do a true power reset (unplug + power drain), then boot with all HDMI unplugged to isolate HDMI-CEC/eARC conflicts (soundbars are a common trigger for black screen or reboots). After the TV is stable, fix Wi-Fi/DNS (forget network, router reboot, WPA2/WPA3 mixed), complete sign-in/time sync, and install the latest TV software/firmware update. Only use factory reset or recovery options if normal boot and updates can’t restore stability.


Why a TV reset doesn’t fix the problem

When a factory reset not working happens, it’s usually because the issue is outside the settings database: power-state glitches after outages, TV stuck on logo due to HDMI handshake, boot loop triggered by CEC/eARC, unstable Wi-Fi/DNS that prevents sign-in and app store loading, or a firmware/software bug that needs an update (sometimes even via USB). That’s why repeating “reset to initial settings” can feel pointless — you’re clearing preferences while the real fault stays.

How to confirm the TV is fully fixed

Test in a controlled way: (1) run the TV for 10–15 minutes with no HDMI devices to confirm no reboot/black screen; (2) reconnect devices one-by-one (save soundbar eARC for last) to catch CEC conflicts; (3) confirm Wi-Fi stays connected and apps load without “no internet”; (4) verify software is updated and the TV time/date stays correct. If it survives a cold start (unplug overnight) without returning to a logo screen or restart loop, the root cause is typically resolved.

TV reset not helping — quick troubleshooting tips

Most cases are fixed by power reset + HDMI/CEC isolation + software update (not repeated factory resets).

Quick path: do a power reset (unplug + power drain), boot with all HDMI unplugged, disable HDMI-CEC if a soundbar causes black screen, then fix Wi-Fi (forget network + router reboot + WPA2/WPA3 mixed + stable DNS). Finally, install the latest firmware update to prevent the problem from returning.

FAQ

Why didn’t factory reset fix my TV?

TV reset not helping usually means the issue isn’t just settings: power-state bugs, HDMI-CEC/eARC conflicts (soundbars), unstable Wi-Fi/DNS, or firmware/software problems. Try a true power reset, unplug HDMI devices, stabilize Wi-Fi, and update firmware before resetting again.

What should I do if my TV is stuck on the logo after reset?

Start with a power reset (unplug + power drain), then boot with all HDMI unplugged to rule out CEC/eARC handshake problems. If it boots normally, reconnect devices one-by-one (soundbar last) and disable HDMI-CEC if the black screen returns.

Can a soundbar cause a black screen or reboot loop?

Yes. A soundbar connected via HDMI ARC/eARC can trigger HDMI handshake and CEC conflicts that look like a TV failure. Test with HDMI unplugged, then adjust CEC/eARC settings and update the soundbar firmware if available.

Why won’t my Smart TV connect to Wi-Fi after a reset?

After a reset, the TV must re-sync time/region/account and reconnect cleanly. Forget the network, reboot the router, try 2.4 vs 5 GHz, use WPA2/WPA3 mixed mode for compatibility, and set stable DNS if the TV connects but shows “no internet.”
