Hisense is renowned for making budget-friendly smart TVs with more natural colors and better contrast than most other brands. But some TV models create problems for users, and it can be really annoying if your Hisense TV closes and refuses to turn on. Luckily, it’s only a temporary issue, and you can solve this problem with ease.
Here’s how to fix the Hisense TV won’t turn on issue.
Hisense TV Won’t Turn On
If your Hisense TV is not turning on, try plugging the power cord into a different outlet. If your TV still doesn’t turn on, disconnect all the cables from the TV and hold the power button for 20-30 seconds. Wait for 25 minutes and turn the TV back on.
If this method doesn’t work, you can follow these troubleshooting methods before contacting Hisense customer support.
1. Check the Power Cord
The Hisense TV may fail to turn on due to a faulty power cord as it gets insufficient or no power supply from the wall outlet.
Steps to Check the Power Cord
Plug in the cord and see whether the red light turns on at all. If you do not see the red light, check the wires for any physical damage or short-circuiting.
If possible, borrow a power cord from a repairer or friend and check if it solves the problem.
2. Try a Different Wall Outlet
If your power cord is working fine, then maybe the issue is with the wall plug. Sometimes, a TV may start and turn off immediately due to a poor connection with the wall outlet.
Steps to Check the Wall Outlet
- Unplug the power cord from the outlet and try other devices on it that need a higher power supply.
- Plug your Hisense TV into a different power outlet to see if it works.
- Try connecting your TV directly to the wall outlet without extensions or power surge protectors.
If this doesn’t resolve the “Hisense TV is not turning on” issue for you, move on to the next method.
3. Troubleshoot the Remote
If the power cord and wall outlet are working fine, and you see a red light on the TV as well, then the problem may lie with the TV remote.
Sometimes, an object placed between the TV’s receiver and remote blocks the transmission of signals. If you’ve placed any object in front of the TV, remove it.
Press and hold the “Volume Up” and “Channel Down” buttons for 15-20 seconds, as it may help to turn the Hisense TV back on.
Steps to Troubleshoot the Remote
- First, remove the batteries from the remote and press all the buttons at least twice to discharge the remote. Put the batteries back into the remote.
- Replace the old batteries with the new ones.
If your TV still doesn’t turn on, replace the old remote with a new one.
4. Reset Your TV
Sometimes, you may face the “Hisense Roku TV not turning on” issue, as the TV blinks a few times but doesn’t turn on. It happens due to configuration issues, which make your TV behave unexpectedly. To fix it, you must reset the device.
Remove the power cable, wait for one minute, and plug it back in.
If this doesn’t work, try this.
- Remove the power cable and all the connected devices from the TV.
- Locate the TV’s power button. You may find it on either the bottom or the back of the TV.
- Press the power button and hold it for 20-30 seconds as it will drain the power from your TV.
- Turn on your TV after 25 minutes using the TV switch, not the remote.
5. Disconnect Any Additional Devices
If you’re using a streaming box, smartphone, or set-top box, your Hisense TV may not turn on if the wires or devices are faulty. Sometimes, you may only hear the TV sound without any picture on the screen.
What to do
- Check the cables of the connected devices or try connecting other devices using the same cord.
- Check the cords for any physical damage and change them if necessary.
- Turn off your TV and then turn it on to see if it lights up momentarily before going dark.
6. Check the Power Supply Board and Backlight
If you’re facing a Hisense TV blinking red light issue, it means the power supply board is faulty.
Another most common problem users face is LED backlight failure. These lights fail due to a shortage in the power supply board. As a result, your TV fails to show pictures, but other functions like red power light and sound work well.
Follow these steps to check the LED backlight failure on Hisense TV:
- Turn on your TV and hold a bright flashlight 1-2 inches away from the display.
- Turn on your flashlight and observe whether you can see any words or pictures on the screen.
- If you can see images on the screen, then your backlight is broken.
Here, the only thing you can do is to take your TV to the repairman for replacement.
7. Hard Reset
If your Hisense TV not turning on after using the above methods, then it’s better to factory reset your TV. It will uninstall all the applications and change the custom settings back to default.
Follow these steps to hard reset your Hisense TV:
- Find the “Reset” hole on your TV.
- Insert a paper clip or small pin inside the reset hole.
- Now, press and hold the pin until your TV restarts.
- You can also do this process on your TV.
- Turn on your TV.
- Go to “Settings.”
- Now, highlight “Device Preferences” and press “OK.”
- Go to Reset > Erase Everything and press “OK.”
8. Unplug External Network Devices
When you see a blue or red power light flashing several times but don’t see anything on the screen, it happens because of a poor connection with the router or modem, an issue with the TV’s motherboard, or a power deflection issue.
Try unplugging your external network devices connected to the TV. Wait for one minute and then reconnect them again. However, you can also try to reset your modem first before unplugging.
9. Troubleshoot Hardware Problems
The most common hardware problems are listed below.
Sometimes, we unplug the TV while it’s on, and then it won’t turn on at all. It indicates that the main fuse is damaged, which you must replace with a new one.
If you see the red power light without blinking after pressing the power button, it means the problem is with the mainboard.
When you press the power button and see a “Hisense TV red light blinking” error, the problem lies with the power board.
If you’re seeing a dim screen, a display image that disappears after 10-15 seconds, or a flickering screen, it means the TV requires new capacitors on its circuit board.
If that’s the case, it’s better to get the TV replaced.
10. Remove the Back Cover of the TV
Before opening the back cover, unplug the power cord from the wall and ground yourself. You can also use a voltmeter to check the electric current flow in the TV.
Caution: Do not remove the back cover if you’re unfamiliar with the TV circuitry.
Once you open the back cover, do the following:
- Check the power board and the main board for short circuits.
- Use the voltmeter to check the LED connectors and arrays to see if they have any voltage.
- Check the TV’s mainboard using your voltmeter to ensure it receives power from the power board.
If you find any issues in the TV circuitry, get support from Hisense customer service.
11. Hisense Customer Support
If none of the above methods work, you likely have a non-functioning TV. It’s better to contact Hisense customer support to get factual information about your TV.
You can either buy a new one or repair the old one. The cost of fixing a Hisense TV often does not make any financial sense, so it’s better to get a new TV.
