Step 3

Re-seat the video and audio input connections to verify a loose cable is not causing the TV's loss of signal. If you have a coaxial cable connected from your wall cable jack directly into the TV, it may have come loose thereby eliminating all picture and sound on the TV. Locate the connection cable or cables of whatever device you are attempting to watch and unplug them from where they plug into the TV. Plug them back in and check for a signal. If there is still no picture or sound at this point, the best option is to contact Panasonic technical support for further assistance.
