Fix 3: Make Sure to Connect Yoru Setup Box Correctly

If you are using a Setup box on your Panasonic TV, you also have to make sure that the Setup box is properly connected to your TV. Therefore, to check that, we advise you to plug out the cable that makes a connection between your TV and the Setup box.

After that, wait for a few minutes, then reconnect them. Now, check if the signal error gets resolved by doing this or not.

However, it sometimes occurs from your service provider’s end; if the issue won’t get fixed even after that, contact your Setup service provider and ask them about this issue. 

Fix 4: Check Your Internet Connection

A poor internet connection may also prevent the TV from functioning properly. So, if you are using your home router to watch your content on TV, it is important to have a reliable internet connection because the poor connection may sometimes be the cause of this error.

Therefore, you can check your WiFi connection for adequate internet speed using the Ookla speed tester website. However, if your WiFi isn’t working correctly, you can power cycle your router/modem once.

Fix 5: Remove Any Connected USB Drive

If you have connected any external USB drive to your Panasonic TV, then we suggest you to remove it. There are chances that your USB drive may have any fault due to which your TV is unable to read it, which further results in this type of issue.

Therefore, you must take out your USB drive and first check it on your PC or laptop if it is working or not. However, if it is not working properly, then your USB drive is damaged.

So, instead of using a USB drive, we advise you to use the Chromecast feature of your Panasonic Smart TV and stream your movie or content using your laptop or phone directly.

So, you must thoroughly check if there is any dent or damage appearing on your TV as well as remote. If so, then immediately contact a technician and ask him to repair it.

There is a huge possibility that your TV will show no signal issue due to some errors or missing system files. In light of this, we recommend you perform a factory reset as it is the last technical option available to you. To factory reset your TV, you can follow these steps: 

  • Initially, press the ‘Home’ button on your Panasonic TV remote control.
  • Select ‘System’ from the ‘Settings’ menu.
