Overview Of Problem

Having trouble with your Sharp Roku TV?

It may be flashing the logo and then going to a black screen.

This issue can be caused by power problems, HDMI issues, or various other factors.

Fortunately, there are troubleshooting steps that you can take to get your device back up and running again.

In this article we will discuss the overview of the problem so that you can have a better understanding of what is causing it. We’ll look at possible causes such as power failure or HDMI connections not being properly connected.

Additionally, we’ll consider any software updates which could help resolve the issue.

By taking some time to analyze these potential solutions and apply them one-by-one in an organized fashion, you should eventually find success in getting your Sharp Roku TV working again like new! With that said, let’s move on to the next section: Troubleshooting Steps.

Troubleshooting Steps

Transitioning from the overview of the problem, troubleshooting steps can be taken to diagnose and rectify any issues with a Sharp Roku TV flashing its logo then becoming unresponsive.

Taking basic troubleshooting measures like power resetting or checking for HDMI connection problems are often simple solutions that might resolve the issue.

If these do not work, contacting manufacturer support may be necessary in order to identify further causes of the malfunction.

The following two bullet points represent two paths one could take while attempting to solve this technical issue:

  • Power Resetting
  • Unplugging the device from the outlet and plugging it back in again
  • Checking connections on either end of the power cord
  • HDMI Connection Troubleshooting
  • Ensuring all cables are securely connected
  • Testing other devices using same cable/port combination as Sharp Roku TV

When addressing potential hardware malfunctions, these steps help narrow down what component is likely causing an issue and if more intricate repairs need to be done by a technician or through manufacturer support. As such, taking time to assess both physical connections and software updates can potentially prevent larger expense later on should an expert become necessary.

It is important to note any error codes displayed during diagnosis so that they can be properly reported when inquiring about product warranty information or seeking out customer service assistance. With this knowledge in mind, resolving network issues associated with a Sharp Roku TV is possible with some patience and effort.

Resolving Network Issues

It is possible that the sharp roku tv flashes logo then goes black due to a network issue. To help resolve this, there are some troubleshooting steps that can be taken.

First, it’s important to check the internet connection on the device and ensure its working properly. This can involve checking any cables connected to the router or modem, ensuring all lights on these devices are active, and verifying if everything else in your home is able to access the internet as normal.

| Step | Description | Result |
| Check Cables | Ensure Ethernet/Coaxial cable firmly plugged-in | Confirm proper connectivity |
| View Lights | Confirm power & activity indicators lit up | Verify proper functionality |
| Test Network | Try other devices (i.e., smartphone) for online access | Validate successful connection ||

Once these steps have been completed and confirmed, you should move onto testing the Roku device itself.

Here you will want to make sure both wired and wireless connections are enabled correctly; this includes double checking passwords associated with either type of connection.

If no progress has been made at this point, resetting network settings may be necessary in order to restore full functionality of streaming services.

Testing out different networks or channels may also help identify where problems lie – especially when trying to isolate an issue between a specific app and its server. Troubleshooting options such as changing DNS servers could also prove helpful here in determining what is causing connectivity issues with certain applications.

With all of these techniques combined, hopefully you’ll find success in resolving any network-related issues with your Sharp Roku TV!

Checking For Firmware Updates

If your Sharp Roku TV flashes the logo and then goes black, it is possible that a firmware update may be needed. It’s important to check if any updates are available so you can resolve the issue quickly and get back to enjoying your television.

To find out if there are any firmware updates for your Sharp Roku TV, go into the settings menu on the device. From there, search for ‘system’ or ‘updates’.

Here, you’ll see an option to manually check for and install new software updates. Select this option and follow the on-screen instructions.

If no updates appear after checking, then you will need to move onto another solution such as replacing power cables or HDMI cords.

It’s also a good idea to make sure you have the latest version of the Roku app installed on all devices connected to your TV.

This ensures that everything is up-to-date and running smoothly – ensuring better performance from your television experience overall! With both these steps checked off, hopefully your Sharp Roku TV should now be working without issues.

Replacing Power Cable And/Or Hdmi Cord

If your Sharp Roku TV flashes the logo and then goes black, replacing either the power cable or HDMI cord could be a solution.

First, check to see if the cables are properly connected at both ends.

If everything is properly plugged in, you may need to replace one of them with a new one.

Make sure that you get the right type of replacement cords for your television model.

You can find replacements easily online. Do some research on what type of power-cable and hdmi-cord work best for your model before making any purchases.

It’s important to make sure that these cords are compatible with your device so they won’t cause further damage to it. Some websites will have tutorials about how to troubleshoot HDMI issues and instructions on how to replace cables correctly.

By taking proactive steps like researching cord replacement options and following instructions, you can help ensure that you don’t end up causing more problems than solutions when trying to fix the issue yourself. To guarantee success, however, contacting the manufacturer for further assistance may be necessary.

Contacting Manufacturer For Further Assistance

If your Sharp Roku TV is flashing the logo and then going black, contacting the manufacturer for further assistance may be beneficial.

There are a few ways to reach out to them depending on your preference.

You can contact via email or phone call, both of which provide helpful customer service representatives that can troubleshoot the issue with you.

For direct support from their website, they offer a live chat feature where you can ask questions directly and get answers in real-time. Additionally, if you have an account set up with them already, you will also have access to additional resources such as FAQs and tutorials.

These articles could help resolve any television related issues without having to contact someone directly.

It’s important to remember that when seeking assistance about your Sharp Roku TV flashing its logo before going black, it helps to have some information ready before reaching out for support. Knowing what model number your device has available allows the customer service representative to send specific instructions tailored specifically for your situation.

This makes getting back up and running easier than ever!


In conclusion, if your Sharp Roku TV is flashing the logo and then going black, you should first attempt to resolve any underlying network issues. If that doesn’t work, try checking for firmware updates or replacing the power cable and/or HDMI cord.

Finally, if none of these solutions are successful, it’s best to contact the manufacturer for further assistance.

For those who have already attempted these steps but still aren’t able to get their television working properly, don’t worry: You’re not alone in this situation and help is available. The customer service team at Sharp can provide support over email or by phone so that you can identify what needs to be done next.

Additionally, they may even be able to suggest additional troubleshooting steps that weren’t mentioned here.

No matter what issue you run into with your technology products, it’s important to remember that there are always resources out there that can provide guidance and assistance when needed. With a little bit of patience and determination, hopefully we’ll soon be back up and running on our Sharp Roku TV!
