If you own a Panasonic LCD TV and are experiencing problems with the device, you can follow a few key troubleshooting steps to try to solve those problems. If these steps are not effective at solving the problem, however, you may want to consult a professional TV technician.

Press and hold the "POWER" button for 7 seconds on the left side of the unit if your TV freezes or is not responding. Wait at least five seconds before powering the unit back on.
Make sure that the air vents on the back of the unit are not clogged or obstructed if the temperature indicator is flashing. The air vents are located on the back lower half of the TV. If the vents are clogged with dust, you can clean the vents by using a damp cloth.
Turn your TV off and wait for at least an hour if the image on your TV is blurry. This is often caused by temperature changes in the room. Waiting for the temperature to settle can fix this problem.
Turn color correction off if you are viewing your TV using an HDMI connection and the image is unnatural colors. For example, reds are replaced by blues. To do this, press the "OK" button on your remote control to open the "Other Adjust" menu. Then, use the channel up and down arrows to select "Color Corr." Change the setting from "ON" to "OFF" by using the volume up or down buttons.
Power cycle the Panasonic LCD TV if the previous steps were unsuccessful. Turn off the TV and unplug the power cord from the wall. Wait five seconds and plug it back in.
