Trouble With a Panasonic Cinema Vision HDTV
After several uses of your Panasonic CinemaVision HDTV, you might begin to experience problems with it. Following a few simple steps and performing your own basic maintenance will save you money, time and frustration. Learn to illuminate causes of a snowy picture and bad sound, double-check your antenna connections, relocate your TV to eliminate screen interference, and determine why sound isn't being emitted.
Adjust your antenna location as a first step toward correcting a snowing picture and splotchy audio. Place the antenna in an open place, preferably. Move the antenna around until you're able to pick up the best signal. Refer to your antenna's User's Manual to adhere to its placement needs.
Confirm that the coaxial cable is properly connected to your television, if your picture is still fuzzy. Turn the TV so you can reach its back panel easily. Check the cable for damage such as cuts, tears or dents. Unscrew the coaxial cable and inspect the receptor for debris. Reattach the coaxial cable to the "Antenna In" terminal, making sure to screw it tightly. This will reset the connection of the antenna to the television. If necessary, check the coaxial cable connection to your antenna or receiver. Disconnect the cable from your source device and inspect it for damage or debris. Reattach the cable firmly to your receiver or antenna.
Move your television to a location away from lights, if your picture looks like it's receiving interference from an outside source and your audio is skewed. Find a central location that is free of too many electrical appliances, lights, medical equipment or vehicles.
Adjust the volume as a first step to correcting a normal-looking screen with no audio. Press the "Volume Up" button on the remote control to increase the volume and confirm that the problem wasn't a low volume. Click the "Mute" button on the remote control, as the "Mute" function (which silences all noise coming from the TV speakers) might have been activated accidentally. Go to the TV and check the "Speakers On/Off" button. If none of these remedies works, change the channel to make sure audio issue isn't just a station issue.
Check your power connection, if your TV isn't receiving a picture or sound. Turn the TV's back to face you. Unplug the power cord from the wall to reset the connection. Wait a few seconds and then replug the cord into the wall. Test the wall outlet by disconnecting your TV from it and plugging in a different device.
