Before starting the troubleshooting process, ensure the proper input is selected on the TV. A wrong input on the TV will display a black screen and may lead a person to believe that the TV is not powered on.
1. Perform a cold restart.
If your Hisense TV won’t turn on, it could be because the leftover electrical charge in the TV’s weak capacitors is preventing certain parts from resetting to their default state. This leaves these parts stuck between being off and on, causing the problem. To fix this, perform a cold restart of the TV, which will reset the necessary components to their default states. If the TV is turned on but you have to repeat the process every time to power it on, consider using a smart plug to avoid the hassle. Another technique that you can adopt is to fully power off the TV, not just put it to sleep. To do so, hold the power button on the remote and then select ‘Power off.’
2. Perform an OTA Update of the TV’s Firmware (if applicable).
If your TV consistently struggles to turn on after being powered off, but a cold restart works, it may be due to outdated firmware causing the problem. In this case, updating your TV’s firmware through an over-the-air (OTA) update can help prevent this issue from occurring again. Keep in mind, this step will only work for people who can turn on their Hisense TVs by performing a cold restart.
3. Reset the TV to factory defaults (using the physical button).
If your Hisense TV won’t turn on due to invalid firmware, it might be because the TV was accidentally powered off during a recent firmware update. To resolve this issue, reset the TV to its factory default settings. Keep in mind that the reset method may vary depending on the specific model.
Reset the TV through the settings.
Reset the TV using the reset button.
Perform a hard reset on the TV using the TV buttons.
4. Perform a local update or reinstall the TV’s firmware.
If your TV isn’t turning on due to being stuck in a firmware loop and is unable to complete the required steps, you can try performing a local update or reinstalling the TV’s firmware to resolve the issue. If your TV is still under warranty, it’s recommended to take advantage of the warranty to either receive a refund or a replacement TV.
5. Check for hardware issues.
If the problem persists, consider reaching out to Hisense support. If your TV is under warranty, you can have it replaced. If it is not covered by warranty, have it repaired for a hardware issue at an authorized service center. For those looking to confirm a hardware-related issue or tech-savvy individuals who prefer to repair the TV themselves, proceed with caution. If you are not confident in your abilities, it is best to let a professional handle it. However, you can follow some basic guidelines: If that is not the case, the issue may be with the PSU (power supply unit) or the main board. You will need to replace the problematic part, but testing is required to isolate it.
