Panasonic produces a range of electrical appliance including TVs, audio devices and computers. Most problems with Panasonic TVs can be resolved by carrying out basic checks or accessing menu options via the remote control. For complex technical issues, you may need the help of Panasonic Customer Support or an experienced repairman.
Image interference on Panasonic TVs may be caused by loose connections. If you are using a coaxial cable, make sure it is securely fitted to the RF socket, which is on the back of Panasonic TVs. Check for any damage to the cable and the metal fitting at the tip. One or both of these may need replacing if damaged.
If the picture on your Panasonic TV is noisy or unstable, it may be due to other devices that are affecting it. This is a common problem in particular with Panasonic LCD screens. Remove any appliances such as vacuum cleaners, electric motors or fluorescent light bulbs, as these may be interfering with the picture.
If you are using composite connections on your Panasonic TV, make sure they are properly connected to the sockets at the rear of the TV. These are usually colour-coded on Panasonic TVs.
If you have no sound, make sure you haven't accidentally pressed the Mute button on your Panasonic remote control. If you are using external surround sound speakers, check that they are securely connected in the right sockets. If you are sourcing a device through the HDMI sockets found at the rear of Panasonic TVs, check that the volume on the device is turned up. Devices such as games consoles and DVD players often have their own volume settings, which can affect the TV output if turned down too low. Larger Panasonic TVs in the plasma and LCD range experience some constant noise due to the cooling fans installed within. This is to ensure the unit does not overheat, and is nothing to worry about.
No signal message
Some Panasonic TVs experience "No Signal" messages that occur intermittently during viewing. These are usually caused by a faulty lead or an external device, such as a games console or DVD player, which is not properly connected to the TV set. Check all cables at the rear of your TV and ensure they are firmly fixed in the correct sockets. This problem can also be caused by anomalies in the settings of your TV when compared to the connecting device. Ensure that any devices are set to the same settings, for instance 1080i or 720i, as your television.
