Potential causes why TCL Roku TV may stop working

some reasons why tcl roku tv may not turn on

After conducting thorough research on TCL TV’s official website and various TV forums, I have identified several potential causes for this issue. According to TCL, as well as some TV owners, the problem may be caused by a variety of factors.

These include a bad power cable connection, a faulty power supply, degraded capacitors within the TV, a malfunctioning on/off switch or button, or hardware malfunctions or failures such as a damaged display or circuit board.




TCL Roku TV is not turning on

In short: To troubleshoot your TCL Roku TV, if it’s not turning on, check the power cord, power button, and remote control. If everything seems to be working properly, factory reset your TV.

Before going into a detailed explanation of the solution, examine the table below to understand the problem at hand better.

Reasons Solutions
Outdated Firmware Update the TV
Faulty cable or outlet Replace them
Damaged mainboard Repair It

Step 1: Troubleshoot related things first.

It’s common for power outlet issues, damaged power cables, or malfunctioning remote controls to cause problems with TVs. That’s why it’s important to check these components before looking at the TV itself.

♦ Check the power cable.

Start by trying the most basic solution first. In my case, I checked the power cord of my TV when I encountered the issue of it not turning on. Although this did not solve my problem, it may work for you!

To ensure your TV is getting enough power, look at the cord connecting it to the wall outlet. Make sure it is plugged in firmly on both ends and not loose or damaged. If the cable looks like it may not be providing enough power, unplug it from both the TV and the outlet, then reinsert it firmly.




♦ Check the power strip.

Once you have verified that the power cord is properly plugged in, check the power outlet. Ensure that a switch or timer does not control the outlet, as this could prevent your device from receiving power.

Additionally, ensure that the outlet is providing enough power to other devices. You can test this by plugging in a lamp or another device to see if it turns on. If the outlet does not have power, connect your TV to another outlet.

♦ Check the remote control.

If these (power outlet & power cord) are working as they should, verify that the remote control is functioning properly.

To do this, first ensure that the batteries in the remote control are not damaged and have enough charge. If the remote control has a power button, try pressing it to see if the TV will turn on in response.

If the TV does not turn on when you press the power button on the remote, try using the power button on the TV itself to see if it will turn on that way.

Note: Consider replacing the batteries at this point (just to be safe)

Step 2: Troubleshoot the TV

If none of those things (power cords, power strip, or remote control) are causing the issue, the problem may lie with the TV itself. This could be due to faulty firmware, damage to the main board, or a software glitch.

♦ power cycle your TV.

TVs are vulnerable to damage when there are power outages or sudden shocks. If this happens, it is possible to clear any problems from the TV’s memory without losing any downloaded content or settings by performing a power cycle.

Here’s how you can power cycle your TCL Roku TV:

  • First, unplug it from the electrical outlet.
  • Then, for about 30 seconds, press and hold the TV’s power button.
  • Wait another ten minutes without turning on the TV.
  • Replug the TV.

Now, try turning the TV on using the power button on the remote or the TV itself. If it does not work, proceed to the next step.

♦ Check the power button to see if it’s stuck or broken.

It is possible that the power button on your TV is not functioning properly, either because it is stuck or because it is broken. If the button is broken, there is no way for you to repair it on your own.

However, if the button is simply stuck due to dirt or dust accumulation, you can try to fix it by taking the following steps:

  • First, check to see if the button is physically stuck. If it is, try gently pushing it in and out to see if it will become unstuck.
  • If the button is still stuck, try using a toothpick or other small object to carefully push it in and out.

Warning: when trying to unstuck the button, be gentle and careful to avoid causing additional damage. Use caution and be gentle.

♦ Update your TV’s firmware.

If your TV’s firmware is not up to date or has become damaged, it may not work properly, or you may face a black screen issue with your TV. TCL releases updates each month to improve the performance of its system and fix small problems. As previously mentioned, keeping your TV’s firmware up to date can help ensure it functions correctly.

However, if you update your TV, there is a good chance that your problem may be fixed. Here’s how to USB update your TCL Roku TV

  • Download the latest firmware update for your TV model from the Roku website.
  • Right-click the downloaded firmware file, then select “Send To,” “Extract” (or “Zip“), and the extraction program loads onto the screen.
  • Connect a USB drive to your computer and copy the downloaded firmware file to the drive.
  • Click “Start,” “(My) Computer,” then right-click the removable device icon and select “Eject.” (Disconnect the USB flash drive from the USB port on the computer once the icon disappears.)
  • Now, insert the USB drive into a USB port on your TV and then power the TV on.

If your TV’s hardware is working properly, inserting a USB flash drive into it will automatically start transferring data to the TV. Once the data has finished uploading, a message will appear on the screen telling you to remove the flash drive from the TV.

♦ factory reset your TV

A factory reset is always recommended to fix any internal software-related error. There are two methods to do that, but use the manual method as you cannot access the TV’s settings.

Remember that this will erase everything, including your data and settings. However, tap on this link to factory reset your TV.

Step 3: Nothing has worked so far. What next?

If the previous methods did not work and your TCL TV is still not turning on, there may be another potential cause.

♦ Cool down your TV.

Televisions generate a significant amount of heat when they are used for long periods. However, if your TV is in a confined space with limited ventilation, it is more likely to overheat. If the internal circuit board has not been damaged, the TV will not turn on again until it has cooled down.

So, allow the TV to rest overnight and remove any dirt or debris from the vents. This will help to ensure that the TV can dissipate heat properly.

♦ Check the TV’s backlight.

The backlight of your TV may have burned out. This can be caused by a power outage or an irregular flow of electricity.

To determine if this is the problem, turn on your TV and hold a flashlight near the screen. As you shine the light on the screen, closely observe whether any image is visible. If you see a faint image, this indicates that the backlight needs to be replaced.

♦ Contact a repairer

If the problem is not related to the backlight, it means that one of the internal components of your TV has definitely been damaged. If you do not have the necessary skills or knowledge to perform DIY repairs, it is best to contact a professional repairer to diagnose and fix the issue.

Trying to repair the TV without the proper knowledge and expertise could lead to further damage. A professional repairer has the necessary tools and experience to diagnose and fix any issues with your TV accurately.

In conclusion, if your TCL Roku TV isn’t turning on, some possible solutions are checking the power cord, unplugging and plugging the TV back in, using a different power outlet, and checking for a faulty circuit board. If these steps don’t work, it may be best to contact a TV repair technician.
