LG TV stuck on logo screen or boot loop — webOS, firmware and power issues
Technician
A few quick questions first:
• Exact LG TV model (e.g. OLED, NanoCell, UHD) and approximate age?
• Does it stop on the LG logo and freeze, or keep restarting in a boot loop (logo → black screen → logo again)?
• Any recent software / firmware update, power outage, thunderstorm, or move to a different house before this started?
• Do you see the red standby light blinking in any pattern when it tries to turn on?
The more detail we have, the better we can tell if this is a simple power reset / software glitch or something that needs main board service — without opening the TV or doing anything unsafe at home.
Technician
Common causes:
• The webOS firmware didn’t finish properly (corrupted update or power blip).
• A software glitch in the startup apps (inputs, HDMI-CEC, network) makes the TV restart as soon as webOS tries to load.
• Less often, a power board or main board fault that only shows up as a TV keeps restarting at the logo.
We’ll start with the safe things you can do at home:
1) A proper power reset that drains the TV’s boards, not just unplugging for a second.
2) Start the LG TV with no external devices attached to rule out HDMI/USB.
3) See if we can get far enough to do a factory reset or firmware reload from the normal menus.
If it still keeps looping on the LG logo after those steps, it’s likely a deeper board issue and you’ll want a service technician — but let’s see how far we can get first.

Step 1 — Proper power reset for LG TV stuck on logo
1) Turn the TV off with the remote if possible, then unplug the power cord from the wall.
2) With the TV unplugged, press and hold the physical power button on the TV itself (not the remote) for about 15–20 seconds to discharge any residual power.
3) Leave it unplugged at least 2–3 minutes.
4) Disconnect all HDMI and USB devices (cable box, streaming stick, soundbar, game consoles, hard drives). Only the power cable should remain.
5) Plug the TV directly into a wall outlet (no surge protector/strip just for this test) and power it on again.
This type of hard reset is usually the first thing LG support suggests for an LG TV that keeps restarting or is stuck at the logo. Tell me what happens after this — does it still boot loop on the LG logo, or does it at least stay on a blank screen or try to load webOS?
Technician
Step 2 — See if we can reach any menu before the reboot
As soon as you power the TV back on:
1) Repeatedly press the Settings (gear) button on the LG remote — sometimes you can bring up the quick settings bar even if the TV is close to rebooting.
2) If you briefly see a menu, look for options like All Settings → Support → Reset to Initial Settings or “General → Reset”. Don’t worry if you can’t reach it before the reboot; just note whether the menu flashes at all.
3) Also try the Input or Home button right after the logo appears to see if it will land on the input list instead of looping.
If we can’t hold it on long enough to factory reset from the normal menu, we’ll stay on the safe side — no hidden service menus — and then talk about when it’s time to let a technician reload firmware or check the main board for you.

• The display/backlight work.
• Power reset didn’t clear it.
• webOS tries to start but crashes → classic LG TV stuck in reboot loop behaviour.
Before we assume it’s a bad main board, a couple more safe checks:
Step 3 — Power source and cooling
• Make sure the TV is not overheating: plenty of space around the vents, not in an enclosed cabinet with hot devices under it.
• Keep it plugged directly into a known-good wall outlet (you already did this, but try a different wall socket if possible). Faulty surge protectors can cause random TV power cycling.
Step 4 — Try a longer power drain
• Unplug the TV again, leave it unplugged for 20–30 minutes, then plug it back in and turn it on.
If after all this the LG TV still won’t boot past the logo, we treat it as a firmware or board level problem — something that’s hard to fix without service tools, but I’ll outline your options so you don’t waste time on random tricks from forums.
Technician
Safe, warranty-friendly things to consider:
• On LG’s support site, many models allow a USB firmware update. You download the exact firmware for your model, copy it to a USB stick, and the TV may detect it during startup. On a TV that’s in a boot loop this doesn’t always work, but sometimes the update screen appears after the logo.
• If the TV is still within LG’s warranty or an extended plan, I’d strongly recommend opening a support case and describing it exactly as you did (“LG TV stuck on logo, keeps restarting, started after update”). That notes a likely software/main board fault rather than user damage.
What I don’t recommend is trying random “secret codes” or opening the back to heat parts with a hairdryer — those tricks can make a repair more expensive or void coverage. If you want, I can walk you through checking the LG support page for your exact model and prepping info for a repair request so you sound clear and technical on the call.
Technician
What a technician or authorized centre typically does:
• Connect the TV to service equipment to reload or repair the webOS firmware at a low level, even if it doesn’t reach the normal menu.
• Check the power board and main board for components that cause instability under load, not just on the splash screen.
• If needed, replace the main logic board — this is often the part that fails when a TV continually restarts on the LG logo.
The good news is: you’ve already documented that the issue started after an update and that you’ve tested it with no external devices, different outlets, and a proper power reset. That’s exactly the kind of information support likes to see when deciding whether it’s a repair or replacement situation.
Technician
Often fixed at home when:
• The TV reaches the home screen sometimes and only occasionally restarts — then a factory reset, app cleanup, or disabling HDMI-CEC can stabilise it.
• The TV was connected through a bad surge protector or overloaded strip and a simple power cycle + direct-to-wall test clears it.
More likely a board / service issue when:
• It never gets past the LG logo or webOS loading dots, even after a deep power reset.
• It reboots at the exact same point every time regardless of HDMI/USB devices.
• You hear relay clicks or see the standby light blink in a pattern, and the TV can’t stay on long enough to do anything.
Your case (4-year-old set, started right after update, consistent boot loop on logo) sits in the grey area — worth trying the safe steps we did, then deciding whether to pursue a repair quote or put money towards a newer TV.
Technician
Quick answer: the accepted fix for LG TV stuck on logo
Accepted first fix for an LG TV stuck on logo or in a boot loop: unplug the TV, hold the physical power button on the TV for about 15–20 seconds, leave it unplugged a few minutes, then plug it directly into a wall outlet with all HDMI/USB devices disconnected. If it boots to webOS, perform a factory reset from Settings > All Settings > Support > Reset to Initial Settings and then reconnect your devices one by one. If it still just loops on the logo, it’s usually time for firmware re-load or main board inspection by LG or a TV technician.
Why LG TV gets stuck on logo screen or boot loop
Most LG TV stuck on logo screen issues come from software or power-related problems. A failed or interrupted webOS firmware update can corrupt startup files so the TV never reaches the home screen. Sudden power loss, voltage spikes, or unstable outlets can cause a TV reboot loop where it turns on, shows the LG logo, and then restarts. In other cases, overheating, a failing power board, or a bad main board can make the TV shut down as soon as it starts drawing more power. That’s why you always start with a proper power reset and clean power test before assuming the hardware is bad.
How to test if your LG TV boot loop problem is really fixed
After you apply the basic fixes, let your LG smart TV run for at least 15–20 minutes. Check that it reaches the webOS home screen, responds to the remote, and doesn’t restart when you open apps or switch HDMI inputs. Try turning the TV off and back on a few times; if it always starts normally and doesn’t freeze on the logo, the boot loop is likely resolved. If it only boots sometimes, or still reboots randomly, capture a short video of the behaviour — that’s extremely helpful evidence if you contact LG support or a repair shop about an LG TV that keeps restarting.
LG TV stuck on logo boot loop — quick troubleshooting tips
Most cases are narrowed down by safe power tests before deciding on repair.
Quick path: do a proper power reset (unplug, hold TV power button, wait a few minutes), start the TV with only the power cable connected, and see if it still loops on the LG logo. If you can reach the menus even briefly, back up settings where possible and perform a factory reset. Avoid opening the TV or using “secret service codes” from random forums — those can void warranties and rarely fix a true LG TV boot loop. If it still won’t boot, document what you tried and contact LG or a trusted TV technician with the model number, age, and symptoms.

FAQ
Why is my LG TV stuck on the logo screen or rebooting in a loop?
An LG TV stuck on logo boot loop is usually caused by a corrupted webOS update, a software glitch at startup, or a hardware issue on the main or power board. Sudden power cuts during an update, overheating, or unstable power can all trigger this. Start with a proper power reset and clean power test before assuming the hardware is bad.
What is the first thing to try when my LG TV won’t boot past the logo?
Turn the TV off, unplug it from the wall, then hold the physical power button on the TV for 15–20 seconds. Leave it unplugged a few minutes, disconnect all HDMI/USB devices, and plug it directly into a wall outlet. If it boots normally, perform a factory reset from the settings menu to clear any leftover software issues.
Can I fix an LG TV boot loop without opening the TV?
Yes, many soft boot problems can be solved with a power reset, factory reset, and checking for firmware updates. If your LG TV keeps restarting at the logo even after that, deeper fixes require service equipment and board testing. Do not open the TV yourself — that’s work for LG or a qualified technician.
When should I call LG support or a TV technician?
If your TV never gets past the LG logo, can’t stay on long enough to reset, or continues to restart after a proper power reset and clean power test, it’s time to contact LG support or a TV repair shop. Provide the exact model, age, and that the issue is an LG TV stuck on logo boot loop and list the steps you’ve already tried.
