First, check the volume and mute settings, especially if there is another person in the house who may have changed them, and check another channel or input to ensure the signal source is not the problem. Next, verify that the sound is set to use the internal speakers, or that the external sound system is set to the input from the TV (some TVs with external sound output connections can be set to disable the internal speakers so they don't interfere with the external sound).

If you have no sound on any input, muting is off, and the volume indicator acts correctly, then the audio circuit on the main board is defective, or the audio power supply needs to be repaired. If your TV has a sound output connection that you have not connected, try connecting it to an external sound system and setting the TV sound to go to the external sound system. If it works, then you have narrowed the problem to the sound power amp in the TV, or to a bad power supply (some TV models have a power output specifically for the audio amplifier, although that is not common).

Most of the time, power supply failures in LCD TVs are the result of burned-out electrolytic capacitors. These are usually identifiable by the domed-up top of the capacitor, as pictured here. Note the flat tops on the good capacitors nearby. If you see these on the power supply board (the cable from the power board connector goes to the power supply), have them replaced with Panasonic FR-series capacitors; these usually have the best combination of price, power handling capacity and longevity.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hello
Your flat panel TVs picture tube base board has soldering loose contact with it. Just unplug your TV from AC mains socket, and open it. Pull out the picture tube base card from the picture tube neck. Pull it out straight, no shake must be there, as it will damage its connecting pins.
Normally, loose sodering are very difficult to loacate, as they will be quite micrscopic in size. Just resolder all the suspected loose sodering point on that board, by applying a little more solder. This will solve your TVs problem. OK.

Hello
Surf through its menu, come to sound settings and look if "Mute" function is set to "ON' or not. If mute function is set to "ON" there will be no sound at all. If it is set to "OFF' it is OK and connect the TVs audio output socket to any known audio souce like amplifier or other. If sound doesn't come from it also, it means that the audio decoder section circuit inside your TV is faulty and should be replaced. If there is sound from the external amp; check the speaker and audio output IC OK.

go to the menue and look for picture prefences look for factury reset and hit it that might bring your factory settings back if it does not you might have a display problem

make sure you do not have a disc in the tray. Press the P.Scan button 2-3 times. You should get the picture back.
