Buying a Hisense TV may have saved you some money, but you still don’t want to replace it if something goes wrong. Sometimes we can experience issues with our TV, whether it’s old or brand new, and it is difficult to determine if your TV is beyond repair. If you have a Hisense TV that is not working, this article covers a number of issues that can be easily resolved.

If your Hisense TV won’t turn on, try changing the power outlet, flicking the mains power switch or resetting the TV. If you have no sound, check the audio output is set to the correct speaker. If you have no picture or a flashing screen, it may be interference or connection issues with your device.

Below are some general troubleshooting tips for a Hisense TV that is not working. With most electronic devices, performing a hard reset, firmware update or factory reset will resolve most issues.

Performing a Hard Reset

A hard reset will drain all the power from the TV, clearing its short-term memory. This will clear away any small faults that may be affecting the function of your TV. Resetting your TV in this way will not remove any of your downloaded content and will preserve your settings.

Step 1: Turn off your Hisense TV and all connected devices.

Step 2: Unplug the TV from the wall.

Step 3: Wait at least one minute before plugging it back in.

Step 4: Reconnect all devices and turn the TV back on again.

Updating the Firmware

Sometimes things go wrong when the TVs firmware has a bug. These bugs are fixed through regular updates, so you should always make sure your TV is up to date. You can set these updates to occur automatically using the steps below.

Step 1: Press the ‘Settings’ button on your remote.

Step 2: Navigate to Support > System Update.

Step 3: Enable ‘Auto Firmware Upgrade’.

If this feature is not available on your Hisense TV, you can manually update your firmware instead, using the steps below.

Step 1: Press the ‘Settings’ button on your remote.

Step 2: Navigate to All > About > System Update

Step 3: Select ‘Detect’.

Step 4: Confirm update if one is available.

Performing a Factory Reset

A factory reset is very effective at resolving issues with your Hisense TV. However, this will erase all downloaded content as well as your system preferences, so you should only do this if other solutions are not working. You can find how to do this below.

Step 1: Press the ‘Settings’ button on your remote.

Step 2: Navigate to System > Advanced System Settings.

Step 3: Select ‘Factory Reset’.

Step 4: Wait for the TV to completely restart before use.

If you are having specific trouble with your TV not turning on, first make sure that the mains power switch is turned on. This is located under the screen. You can also try plugging it into a different power outlet in case the outlet is faulty.

You should also make sure the TV is not in ‘Standby’ mode. However, the TV should always wake up from ‘Standby’ mode when you press the power button on the remote.

If the LED at the front of the TV is on, then your TV is getting power. A black screen may mean that the screen is not working. You can find solutions for this below.

If you have checked the power supply, including cables, the mains power switch and different wall outlet, you may have a bigger issue that requires a Hisense technician.

Hisense TV Has No Sound

The simplest explanation for no sound on your TV is that the volume is turned down too low or that you have the TV on ‘Mute’. These buttons can be found on both the remote and the back/side of the TV. Make sure to try both of these options because it may be the case that a button is broken.

The next thing you will need to check is that your TV speakers are enabled. You can do this using the following steps.

Step 1: Press the ‘Settings’ button on your remote.

Step 2: Navigate to Sound > Advanced Audio Settings > TV Speaker & ARC

Step 3: Select ‘TV Speaker’ to enable the sound on your TV.

If you have external speakers connected, make sure this speaker is on and turned up. You can find the settings for an external speaker in the same place as above, so make sure you have enabled your external speaker instead of the TV speaker. You can also alter how the audio is send to a speaker under the ‘Audio Out’ menu.

If the sound is only malfunctioning when using an external device, such as a gaming console, make sure that it is plugged in correctly to the TV. You should also check that you are using the correct type of cable for your device.

Hisense TV Has No Picture

If the screen is not working on your TV, you should still be able to hear the TV playing in the background. This may be an issue with the TVs circuit board, but you can work through the following instructions to see if there is a simpler explanation.

If you are not getting an image when operating an external device, you may be on the wrong input channel. The device connected to ‘HDMI 1’ should be visible when you select ‘HDMI 1’ from the input menu. If you have given each input a nickname, cycle through each input channel to see which one is in use.

You should also check that the cable connecting your device to the TV is not loose or faulty. Try a different cable if you need to. If the device is a set-top box for your TV channels, you will need to check the antenna or check that the channels have been programmed/tuned.

The picture settings on the TV should not allow you to adjust them to the point of not seeing an image at all. However, if you would like to try resetting the colour settings on your TV, follow the steps below.

Step 1: Press the ‘Settings’ button on your remote.

Step 2: Select ‘Picture’. This should be the first option, so simply press the ‘Ok’ button to do this.

Step 3: Select ‘Restore Defaults’. This is the last option on the Picture menu, but each model will have a different variation of the menu. You can navigate to the bottom by pressing the down arrow several times and pressing ‘Ok’ on the remote.

Step 4: You will then need to confirm the reset by selecting ‘Yes’, or pressing the ‘Ok’ button on the remote.

If you have a smart TV that does not have a ‘Settings’ button, you will need to use the following steps instead.

Step 1: Press the ‘Home’ button on the remote.

Step 2: Press the ‘Up’ arrow to get to the top of the screen. This should require two presses on the button.

Step 3: Press the ‘Right’ arrow five times and press ‘Ok’ to select ‘Settings’.

Step 4: Press the ‘Down’ arrow four times and press ‘Ok’ to select ‘Device Preferences’.

Step 5: Press the ‘Down’ arrow seven times and press ‘Ok’ to select ‘Picture’.

Step 6: Continue pressing the ‘Down’ arrow to get to the bottom of the menu and press ‘Ok’ to select ‘Reset to Default’.

After you have tried different inputs, you should perform a hard reset on your TV. It will be difficult to perform a factory reset without the image, so you may have to contact a Hisense technician if a hard reset does not work.

Hisense TV Flashing

For a flashing screen, you should start with a hard reset, detailed at the beginning of this article. It may be caused by an error which will be fixed when the power is drained and the internal memory is dumped. If this does not solve the issue, you can try the suggestions below.

Check the Input Cable

If the flashing screen only occurs on one input channel, such as HDMI 2, it may also be a loose or faulty cable in that port. If this is the case, check all input channels, including HDMI, coaxial (satellite TV), composite, etc.

You will need to unplug the corresponding cable and re-insert it tightly in both the TV and device. However, if the flashing occurs on all input channels, it is likely a different issue.

Check Your TV Settings

Some people have found that having their TV in ‘Energy Saving’ mode causes the screen to flash. You can change this using the following method.

Step 1: Press the ‘Settings’ button on your remote control.

Step 2: Navigate to Picture > Picture Mode.

Step 3: Select ‘Standard’ or something other than ‘Energy Saving’.

Look for Grounding Issues

The issue may also be related to the electrical grounding of one of the devices connected to your TV. Try disconnecting all devices to see if this solves the issue. If it is an issue with grounding, you will either need to use a different power socket or replace the power cable.

Look for Interference

Some appliances or electrical devices can cause the TV screen to flicker. Make sure things such as electrical tools, mobile phones or fans are moved away from the TV.
