The Hisense Roku TV error 003 means that there has been a problem with processing the TV firmware update request.

The error often occurs as a result of network issues, corrupted files, or interference problems with the Hisense Roku TV.

Let’s get started!

How to Fix the Hisense Roku TV Error 003 Code?

Note: The Hisense Roku TV can be updated at “Settings” → “System” → “System Update”.

1. Unplug the Hisense Roku TV

A simple power cycle can resolve most of the Hisense Roku TV’s non-lasting problems, such as error 003 and persistent update failure.

All you have to do is disconnect the TV power cord for a longer period until all of the electricity drains completely.

Here’s how to power cycle the Hisense Roku TV:

• Unplug your Hisense Roku TV from the wall outlet.
• Wait for 20 seconds until all of the power dissolves.
• Reconnect the TV and check if the cord is secured.
• Go to Settings → “System” → “System Update”.

Tip: We recommend removing third-party devices from the power setup of the TV and verifying that there isn’t any damage to the power cord. 

2. Renew the Hisense TV Wi-Fi

If you’re still unable to process the firmware update due to error 003, then the issue is probably with the Wi-Fi connection of the Hisense Roku TV.

Well, you should reconnect the TV to your home network through the wireless options and attempt to restart the update from the “System”.

Here’s how to renew the Hisense Roku TV Wi-Fi:

• Turn on the Hisense Roku TV using the remote.
• Go to “Settings” from the Roku TV Home Screen.
• Navigate to “Settings” → “Network” → “Wireless”.
• Press “Set up new Wi-Fi connection” on the page.
• Select the router’s Wi-Fi and enter your password.
• Wait until the Hisense Roku TV pairs successfully.

The Hisense Roku TV can connect with both 2.4 GHz and 5 GHz Wi-Fi, so make sure to test on each one if you have a dual-band router.

If the TV was already connected to the 2.4 GHz band, for example, we recommend switching it to the 5 GHz to test.

3. Power Cycle the Network Router

An unstable Wi-Fi router connection may prevent your Roku TV from completing the software update and result in error 003.

The next step is to power cycle your router the same way as you did with the TV, to reset your network and resolve underlying problems.

Here’s how to power cycle the network router easily:

• Unplug your router from the power source outlet.
• Allow 20 seconds for the router to fully discharge.
• Reconnect the router to the power source tightly.
• Wait 1 minute for the router to restart completely.

Once all LEDs on the router turn solid green and stop flashing, it means that the network is back online.

Reconnect the Hisense Roku TV to the network following the instructions in solution #2 and attempt to start the firmware update again.

4. Reset the Hisense Roku TV Cache

Potential software glitches in the Roku TV system prevent the update process or cause error 003 Hisense Roku TV, along with repeated update failures.

Thus, the next step is to clear the Hisense Roku TV cache data and refresh the system without affecting any of the TV settings.

Now, follow these steps to clear the Hisense Roku TV cache:

• Press “Home” on the remote control 5 times
• Press “Up” once, then “Fast Forward” twice.
• Wait until your TV cycles through the settings.

The fast cycle through the settings will last for roughly 10 seconds, then the TV will power off.

The TV will power on by itself after several seconds, hence don’t press anything on the remote. 

Note: Clearing the Roku cache data also helps improve the TV performance significantly. 

5. Test Roku on a Mobile Hotspot

Your home Wi-Fi might be too unstable for the Roku TV to complete the software update, so we recommend temporarily switching to the mobile hotspot of your smartphone.

Make sure you have a sufficient amount of mobile data left (MB/GB), and then proceed with the steps below!

Testing on mobile hotspots helps determine whether the TV is disconnecting from the Wi-Fi or there’s a problem with the network or ISP.

Step #1: Set Up the Hotspot

On your phone, go to “Settings” → “Personal Hotspot” or “Mobile Data”, enable the hotspot and set it to 2.4 GHz, before creating a simple password.

Make sure the hotspot SSID doesn’t have any special characters, then turn it on and note the hotspot’s password for the next step.

Step #2: Change the TV’s Wi-Fi

On your Roku remote, head to “Settings” → “Network” → “Wireless” → “Set up a new Wi-Fi connection”.

Wait for the network list to load and select the mobile hotspot of your smartphone.

Wait for the TV to connect, then go to “System Update” in the settings and attempt to restart the firmware update process.

Note: Keep your smartphone at a 10–15 feet distance from the TV while testing the update!

6. Update Roku Offline Via USB

Well, your Hisense Roku TV has a built-in system function that allows it to update over USB if no Wi-Fi or Ethernet network is currently accessible.

All you need is a 4GB–16GB USB flash drive that’s compatible with one of the inputs on the TV and a connected computer or laptop.

Follow these steps to update the Hisense Roku over USB:

• Visit tvupdate.roku.com, and select the Hisense brand.
• Input the Hardware ID and serial number of the device.
• Check the ID/number at “Settings” → “System” → “About”.
• Download the update.roku file, save it to your computer.
• Insert a USB flash drive and copy the file to the directory.
• Safely eject the USB and plug it into the TV’s USB port.
• Navigate to “Settings” → “System” → “System Update”.
• Press on “I can’t connect” to switch to the USB directory.
• Enter the 12-digit code from tvupdate.roku.com on the PC.
• Now, copy the 6-digit code and type it into the TV’s options.
• Wait for the update procedure to begin and wait for the TV.

Alert: Do not power off or interact with the Hisense Roku TV in any way during the OS update!

7. Update Hisense Roku Over Ethernet

If the TV Wi-Fi connection keeps failing, you should update the firmware version over Ethernet instead.

There are several requirements for using Ethernet for the update:

• The TV must have a high-speed Ethernet jack.
• The router must be within a 10–15 feet distance.
• There must be an empty yellow LAN router port.

Step #1: Connect the TV

First, connect the Hisense Roku TV with the router using a standard, high-speed Ethernet cable and ensure the cable blinks green on the ends.

One end of the Ethernet cable goes into the LAN port of your router, and the other connects to the Ethernet port on your Hisense TV.

Step #2: Set Up the Ethernet

If the cable is blinking, then open the TV settings and go to “Settings” → “Network” → “Wired” to set up the Ethernet connection of the TV.

Follow the on-screen steps to assign a static IP address to the Hisense Roku TV.

Step #:3 Test the Update

If the wired setup has been successful, go over to “Settings” → “System” → “System Update” and attempt to start the firmware update.

Note: Ensure the router is online before attempting the firmware update!

8. Reset the Hisense Roku TV OS

Since it is still unclear whether the error code is on a system or network level, a factory reset will erase all of the Hisense Roku TV content and possibly eliminate the 003 error.

Here’s how to factory reset the Hisense Roku TV:

• Press the “Home” button on the TV remote control.
• Go to “Settings” → “System” from the system tab.
• Select “Advanced system settings” in the settings.
• Now, press “Factory reset” to access the next tab.
• Select “Factory reset everything” from the options.
• Follow the instructions to factory reset the TV device.
