TCL TV Won’t Turn On – What to Do?

Tcl TV Won’t Turn On - What to Do

Basic Troubleshooting Steps

To troubleshoot basic issues with your TCL TV that won’t turn on, check if the TV is plugged in and test the outlet it’s connected to. If that’s not the issue, move on to checking the remote and batteries, and try powering on the TV manually. These basic troubleshooting steps can often resolve the issue and get your TV up and running again.

Check if TV is plugged in

Having trouble turning on your TV? Don’t call a technician yet – start with the basics. Check if it’s plugged in correctly! Here’s a 5-step guide:

  1. Look for the power cable at the back of your TV.
  2. Verify that the cord is connected properly to both the outlet and the back of the TV.
  3. Check for any signs of damage or frayed wires.
  4. Flip the switch on both ends of the cable.
  5. Plug another device into the electrical socket to check for power.

Note: some TVs have external power adapters. Make sure both ends are connected and working. Then try turning on your TV.

If it still doesn’t work, try a different power outlet or a surge protector. Faulty outlets and surge protectors may cause problems with powering up gadgets, like TVs. Lastly, make sure your outlet has electricity – blaming your TV is just unfair.

Test the Outlet

Troubleshooting electrical issues? Start with the basics. Unplug any device and plug a new one in the same outlet. If it doesn’t turn on, you may have a faulty outlet needing a professional repair.

Check your electrical panel. Overloaded or tripped circuit breakers can cause issues with outlets or entire rooms.

A friend of mine had many outlets not working. Testing each outlet revealed they were all working. The issue: a tripped breaker in the electrical panel. Resetting the breaker fixed the problem.

Sometimes the simplest solutions work! But first, check your remote batteries!

Check Remote And Batteries

Troubleshooting? Check the remote and batteries first! Fresh batteries are key for a top-notch electronic experience. Here’s the drill:

  • Insert batteries with positive end first.
  • Replace old or expired batteries.
  • Use a battery tester to make sure they have enough charge.
  • Verify that the remote is turned on and connected.
  • If necessary, reset with fresh batteries or follow instructions.
  • Buy a new remote if nothing else works.

Don’t skip this step or you risk wasting time and energy. Take my word for it – I recently had trouble connecting my TV to a soundbar. It was only after replacing the remote’s batteries that everything worked. If I hadn’t checked the remote, I may have been stuck with a bigger problem!

So, if all else fails, just remember the classic IT advice: turn it off and on again.

Try Powering On Manually

Nothing seems to be working? Struggling to even turn your device on? There’s a quick fix for power-related issues: ‘Try Powering On Manually’. Here’s how:

  1. Unplug any cables – USB, HDMI or VGA.

Be careful. If you’re not experienced, seek professional help. Advanced tech requires effective troubleshooting. Don’t neglect to check your power supply capacitors when having issues – it could save your device!

Remove Any USB Devices And Memory Cards

It’s often the simplest strategies that are the most effective. Before delving into your system to solve a problem, an easy place to start is by removing any USB devices and memory cards connected to your device. Here’re some tips on why this is significant:

  • USB sticks can contain malware that interferes with software processes.
  • Memory cards can wear down and lead to data erosion, causing processes to malfunction.
  • If connected devices use too much power, it can interrupt essential system functions.
  • Misfiring input/output processes from these devices can cause conflicts with kernel operations on your device.
  • Incompatibility issues when attaching older USB version devices can lead to undetected malfunctions further into your system’s hardware.
  • Physically removing devices attached to external ports ensures no further damage as you work through more complex troubleshooting procedures.

Though simple, ensuring these connections are removed prior to attempting anything else could help you save hours looking for faults deeper inside your hardware. To emphasize the importance of this step in advanced troubleshooting, let me share something I experienced a year ago. I was ecstatic about my newly purchased headset with a mic that came through Amazon Prime. On the first day, everything worked great; then it happened―my computer crashed as soon as I plugged in my new USB headset. After battling for half an hour, I realized taking out the other USB-based auxiliary devices would have been one of the swiftest solutions- even though I hadn’t thought of it at first glance!

Factory Reset Your TCL TV

  2. Choose the ‘System’ option.
  3. Tap on the ‘Advanced System Settings’ and then select ‘Factory Reset.’
  4. You’ll be asked to confirm the action, so tap yes.
  5. Your system will now reset. When it’s done, you will have a brand new factory reset TCL TV!

Remember, resetting a device wipes all data, so make sure to back up everything before you start. Be sure to have all your questions answered before following these steps.

A user reported an issue with their remote not functioning properly due to software glitches. After they tried everything, we suggested they reset their TCL TV by following the steps above. After doing this, all issues were resolved!

Remember: Some devices need special tools to take off the back cover safely. Handle electronics carefully during inspection to avoid electrocution.

Pro Tip: Before inspecting, make sure you’re smarter than the TV’s refresh rate!

Check the TV Mainboard

To find out if the hardware issues on your TV are caused by the mainboard, do this:

  1. Switch off the TV and unplug it.
  2. Look for the mainboard, usually in the middle or bottom of the TV.
  3. Check for burning marks or bulging capacitors.
  4. If everything looks normal, unscrew and disconnect cables from the board.
  5. Examine both sides of the board. You may use a magnifying glass.

Note: Checking the mainboard may not guarantee that hardware issues are resolved. Other components of the TV could be the cause.

For safety, somebody with experience in electronics repair should do the check. If you don’t know how to open and handle the TV parts, get help from a professional.

Manufacturers can release updates or patches for mainboards to fix bugs or issues. Check if there are any available updates for your TV.

Bring a light source to make sure you can see the mainboard properly.

Test the backlight LEDs

Test your backlight LEDs with this quick and easy 5-step guide:

  1. Blank the screen.
  2. Max out the brightness.
  3. Shine a flashlight on the screen while powering up the device.
  4. If the display content is visible, then the backlights are not working.
  5. Repeat steps 2-4 using different displays.

Not all screens have backlights, so this method may not apply. If you need help, consult a professional or refer to the user manual. To fix backlight issues, try adjusting your power settings and color contrast. This might remove any black spots from the screen. Best of luck!


Don’t panic if your TCL TV won’t turn on! Here are a few things to check:

  1. Plug it in and make sure the power cord and outlet are okay.
  2. If it still doesn’t work, unplug the TV for a few minutes and try again.
  3. Check if the remote and TV buttons are functioning.

Also, make sure there’s no interference from other devices. Wi-Fi routers or microwaves can cause signal problems. Move these devices away from the TV if you think they may be causing the issue.

Mistakenly, if you still face the same problem, refer to TCL customer service. My friend had a similar problem. She contacted customer service and followed their steps. She realized her TV needed a firmware update. After that, it worked perfectly!
