Worried with Hisense Roku TV White Screen? (Do This First!)

We know the struggle when you’re ready to watch your favorite show, but the Hisense Roku TV white screen stares back at you.

No picture, no menu, just a blank, unresponsive white screen. We’ve all been there, so don’t worry.

In most cases, the white screen could indicate a source selection problem, a faulty input device, or a critical TV software issue.

We will walk you through the easy steps to fix it and get back to watching in no time.

8 Easy Solutions Against the Hisense Roku TV White Screen!

Note: Have you checked if the TV still has audio? If there is, the TV is still functional, and the white screen could be display or backlight-related. 

1. Drain the Hisense Roku TV

The white screen on your Hisense Roku TV may occur due to a temporary system malfunction, disrupting the functionality of the display.

So, we recommend power cycling your television by disconnecting it from the power outlet, which effectively resets the system by draining the power.

• Disconnect the TV from the power, wait 20 seconds, reconnect, and power on.

This procedure allows the Hisense TV to reboot, potentially resolving the display malfunction.

Whilst waiting for the TV to discharge, ensure all of the power equipment is in proper condition and check for damage on any of the equipment. 

2. Change the Roku TV Source

Sometimes, the white screen on your Hisense Roku TV simply appears because of the currently selected input source.

The Hisense TV has a button on the bottom panel (left, middle, or right) that, when pressed once, opens the TV’s “Inputs” menu.

You can navigate this menu with the arrow keys on the remote and switch the current input to “Home”, especially if you’re currently viewing something through HDMI.

So, if you can see the menu, this immediately tells you that the TV display is working, so the issue is with the source.

3. Disconnect Third-Party Devices

Disconnecting potential third-party devices that could interfere with the TV broadcast can help isolate the problem and restore the screen to normal functionality.

If you’ve enabled the “CEC” settings in the Hisense TV settings, the TV will automatically switch to a detected HDMI input.

Third-Party Devices to Disconnect:

• Gaming consoles (e.g., PlayStation and Xbox)
• Streaming devices (e.g., Fire Stick, Chromecast)
• Soundbars or external speakers/theatre systems.
• DVD, Blu-ray players, or any type of disc reader.

Disconnect all of these devices, then reboot the TV by disconnecting the power adapter.

Then, hold the “Power” button on your Roku remote for another ~30 seconds until the unit discharges.

Quick Note: The only cable connected to the Hisense Roku TV must be the power adapter!

4. Use Voice Menus to Reboot the TV

Note: This solution requires a voice-enabled remote to access the voice menus!

If you only see the Hisense Roku TV white lines on screen, despite power cycling the television and attempting to change the input source, this could be an indication of a deeper system glitch.

Therefore, you can use the voice menu to initiate a system restart and reboot the TV effectively.

• Press the “Microphone” button on the voice remote, then say “Settings,” then “Power,” and finally “System Restart” to reboot the TV.

Wait until the TV powers off and check if the white screen or the white lines are still there.

If the voice reset does nothing, repeat the instructions, then unplug the TV’s power cable.

5. Change the Hisense Roku A/C Outlet

The issue might be caused by an unstable power supply from a faulty outlet, and switching to a different outlet can eliminate inconsistencies with the power flow.

First, unplug the TV from its current outlet, find a new one that’s working well, and plug the TV in there. 

Use your remote to turn on the TV and check if the display is still white. In the meantime, test another electrical appliance in the previous outlet.

Note: Try connecting the Hisense Roku TV directly into the outlet rather than into the extender!

6. Roll Back the Hisense Roku TV OS

If you’ve recently updated the Hisense Roku TV firmware, there’s a persistent chance that the white screen is caused by OS corruption.

This is why we recommend reverting your Hisense Roku TV to an older firmware version and checking whether the white screen problem is there.

Step #1: Downgrade Preparation

You’ll need a 2.0/3.0 USB flash drive, a computer, and an open USB port on your TV to start the process.

So, make sure you have all of that and check if your computer is connected to the internet.

Also, format the USB flash drive to “FAT32” before uploading the Roku firmware files. 

Step #2: Download the Firmware

On your computer, go to the Roku Firmware Page, pick Hisense, then enter the TV hardware ID and serial number from my.Roku.com.

Then, download the older OS file that your TV was using before you recently updated the software. 

Note: You must sign in at “my.Roku.com” to check the Hisense Roku TV details!

Step #3: Transfer the File to USB

Plug the USB into your computer and copy the update.roku file to the USB’s main folder, and wait for it to fully transfer.

Now, safely eject the USB drive so nothing gets corrupted, then take it over to your TV and plug it into the available USB port.

Step #4: Upload the Update File

Plug the USB into the TV’s USB port, wait for a code on the screen, enter it on the Roku site, and then follow the prompts to install and restart the TV.

If you see “Update file could not be opened,” reformat the USB and try again.

Note: The TV should read the update file automatically if everything is set up correctly!

7. Flush the Hisense Roku TV Cache

You can resolve temporary issues with the Hisense Roku, even if the TV is not responding, by inputting a cache reset combination through the remote control.

However, you must be certain that the remote is functional and has active batteries; otherwise, the cache reset will not work.

• To reset the Hisense Roku TV cache, press the “Home” button 5 times, then the “Up” button once, then the “Rewind” button 2 times, and the “Fast-Forward” button once.

Note: Before starting the cache reset, ensure the TV power cord is connected securely on both ends and replace the batteries in the Hisense Roku remote control.

8. Conduct a Thorough HW Inspection (Advanced)

Warning: Disassembling the Hisense Roku TV will result in a permanent warranty void!

The Hisense Roku TV white screen might not be software-related, and that’s why it’s important to check if there are issues on the hardware side.

So, the Hisense Roku TV has several crucial components that define the performance of the display. 

• To access the TV Hardware, unplug the TV, and use a screwdriver to remove the 8–10 screws on the back panel.

Here’s what to check once you’ve accessed the hardware:

#1 Check the T-Con Board

The T-Con board can disrupt the Hisense Roku TV picture if it’s not working properly and make the screen all white.

The T-Con board is usually a small rectangle in the middle, so you need to check for burn marks or broken parts. 

Finally, make sure it’s interconnected properly with the MCB.

Tip: You can order a cheap T-Con board replacement (roughly $20) from online stores!

#2 Inspect the Ribbon Cables

Faulty ribbon cables can cause issues with the TV if they are loose or torn.

Look at the cables connecting the T-Con board to the screen, see if they’ve sustained damage or have been unplugged, and push them back in gently.

Tip: To replace a defective ribbon cable, unplug it from both ends and reinstall the replacement. 

#3 Examine the TV Backlight 

If the Hisense Roku TV backlight is defective, the screen might turn any color, including black and white, or show horizontal lines.

You can use a flashlight in a dark environment while the TV is turned on to check if the pixels are illuminated.

#4 Inspect the TV Motherboard

The mainboard is the brain of your Hisense Roku TV, and if it’s broken, it won’t send a picture to the display, leading to a consistently black or white screen.

The motherboard can be found right behind the LCD panel and looks like a small PCB board with plenty of cables coming out of it.

Also, look for burnt spots, frayed wires, or faulty connectors to check if there’s a fault with the component.

Tip: We recommend bringing the Hisense Roku TV in for repairs if there’s a motherboard fault!
