    • NOTE


  • Will the DY-WL5 wireless adapter work with my TV?
  • Why did some or all of my Remote Sharing messages disappear?
    Shared content will only be saved for 30 days.
  • Why are there black bars on my screen when I use my SC-BTT190/195/196/490?
    Most movies are filmed in a format wider than your TV's 16:9 aspect ratio. Some discs adjust the picture to eliminate the borders while other discs keep the film's original format.
    When the disc's content is in wide-screen format, then black bars are displayed at the top and bottom of the picture.
    Changing the TV's FORMAT (or aspect) setting to a ZOOM mode may eliminate the bars. However, the zooming effect trims the sides of the pictures, so some content is cut off.
    Older content is filmed in 4:3 (old TV) format. When playing 4:3 content on your HD TV set, black bars are displayed on each side of the screen.
    To eliminate the side bars, change your TV's FORMAT (aspect) settings. For example, Panasonic TV's have a format mode called "JUST" which is specially designed to stretch a 4:3 image to fill the screen.
  • Why are some of the options in the Panasonic TV Remote 2 App grayed out?
    Options that are greyed out in the Panasonic TV Remote 2 App are not available on the TV the app is connected to.
  • Where can I order parts for my product?
    You can order parts and accessories for your machine from our Parts & Accessories Department at 1-800-833-9626.
  • Where can I find the firmware for my device?
    Click here and enter your model number into the Get Support Now search box. Once your model appears, click on the "Support" link under the picture of your model. This will bring you to the Support Page for your model. If there are any firmware updates available for your model, they will be located under the Drivers & Downloads tab. If there is no Drivers & Downloads tab, your device's firmware is up to date.
  • What should I do if my TV is making a buzzing or humming noise?
    Mute the TV to verify if the issue is with a blown speaker. If the noise is still heard with the TV muted, unplug all connected devices from the TV. If the noise goes away, connect the devices back to the TV one at a time to determine which device is causing the noise. Contact the manufacturer of the device causing the issue for further troubleshooting. If the noise does not go away when you disconnect all devices, try connecting the TV directly into the wall with no surge protector. If the noise goes away, you may need to replace your surge protector. If the noise does not go away, inspect your screen for cracks or other signs of damage to the TV. If there are no cracks, make sure that your TV is not located at a high altitude such as 7,000 ft. or more above sea level.
  • What should I do if my remote is not working?
    • Ensure that no object, such as a center speaker or soundbar, is blocking the bottom front of the TV.
    • Check that the batteries are fresh, are of the same type and are installed with the correct polarity (+ & -).
    • Try a remote reset by removing the batteries and pressing every button on the remote twice. Lastly, re-insert the batteries.
  • What should I do if my Bluetooth or USB keyboard does not work with the Amazon Videos on Demand app?
    Use your remote control to manipulate the keyboard function within the Amazon Videos on Demand application.
  • What should I do if I forget the my Home Cloud password I have set for my account?
    Click Here then click on Forgot Password.
  • The remote control for my Panasonic device is no longer functioning. Is there a remote control code available that will enable me to use another manufacturer's remote to operate this device?
    You will have to contact the remote's manufacturer for the codes needed.
  • How do I turn on my TV with the Panasonic TV Remote 2 App?
    The Panasonic TV Remote 2 App can only control the TV once it is turned on and connected to the same network as the IOS or Android device that has the Panasonic TV Remote 2 App installed.
  • How can I remove the black box that is appearing over most of my TV picture?
    Enter the TV's Setup menu and change the "Closed Caption" setting to OFF.
  • How can I register for the warranty of my product?
    You may register your products online by clicking here. It is not necessary to submit this form in order to effectuate the limited warranty. As long as there is a copy of the receipt, your product warranty begins from the date of purchase.
  • How can I install Adobe Flash on this TV?

  • Does this TV support streaming of 4K content through the Netflix Application?
  • Does my TV support Remote Sharing?
  • Does my TV support my Home Cloud?
  • Can I use the Remote Sharing function of my TV with an Android device?
