Frequently Asked Questions (FAQ) Questions Why doesn't the remote control work? Why is there no picture or just a blue, black or snowy screen being displayed? Answers Check that the batteries are fresh, are of the same type and are installed with the correct polarity (+ & -). To operate other devices, such as changing channels when using Cable or Satellite boxes, or operating non-Panasonic Blu-ray players, use the remote supplied with the device. Ensure that the power cord is plugged in and the TV is turned on (front red LED light should be on, not blinking) Press the INPUT button on the remote to select the correct input source. Ensure all connections are correct and secure. When using external video source, such as a Cable/ Satellite box or DVD player, ensure that the device is on and functioning correctly. Press MENU on the TV's remote control. If the menu is displayed, then the TV is working; recheck above steps. Why does my picture quality not look like it is in High Definition? Press INFO button on remote to confirm type of signal being received.HD signal should be 720p, 1080i or 1080p. Select a High Definition channel from HD source (Cable, Satellite,Fiber optic or antenna). HD channels sometimes broadcast non-HD content. Ensure that HD source (HD box, Blu-ray player, etc.) is connected to TV via either HDMI or Component cable and set to output HD video signal. Why did the network connection fail? If connection fails, contact your Internet service provider or router/modem manufacturer to check for firewall, content filter or proxy settings that may block TV from accessing the Internet. How can I hear the TV's sound through my Home Theater? If your Home Theater has an HDMI-ARC Out, then connect it to the TV's HDMI 2 (ARC) input using an HDMI cable. If HDMI-ARC is not available, then connect the TV's DIGITAL AUDIO OUT to the Home Theater using an optical cable or connect to the headphone jack. 27
