The sound on my tv and dvd combo went out. How do I get it back?


check to make sure speakers not turned off (audio menu) and get up to check if any sound at all from speakers as sometimes the plug inside will come loose disconnecting the speaker/s


Other than that you may have a problem in the audio circuit and that might not be economical to fix

I can`t get any audio. Its not on mute. I can turn the audio up and down on the screen


Hello,

First check that any muting control is not activated. This might be a button on the remote or set itself. If you have a headphone jack, it may have dirty contacts as plugging in a headphone usually mutes the speaker.

If the set is mono or only one channel of a stereo set is out, then check for bad connections to the loudspeaker. Test the loudspeaker by disconnecting one of the wires (with the power off!) and measuring its resistance with an ohmmeter (it should be less than 100 ohms - probably less than 8 ohms). Or momentarily touch a 1.5 volt battery to the speaker terminals - you should get a click or pop from the speaker.

Next, trace back from the speaker output terminals to the circuit board and look for bad solder connections or a loose or dirty connector.

If these tests do not reveal anything, you probably need a scope (or audio signal tracer) and schematic. Or at least the part number off of the chip. Is the final amp a chip also or just a transistor? Have you tested the transistor? If there is little or no buzz from the speaker, that would indicate a problem fairly near the output. If the tuner/if were bad, I would expect some noise/hum pickup from the low level audio stages. Get the part number off of the chip. If it is in a socket, check the contacts for corrosion or looseness.
Hope it works...

I can't get the sound to come on. When I mash the volume button i


You gave no brand and model, but some general possibilities. Check the menu in the audio/sound options. Be sure the speakers are "ON" as sometimes they get inadvertently switched off. Some models have a manual speaker switch in the back. Also if this has a headphone jack this could possibly be causing the prob. The jack on some combos can go bad. Plug in a headphone and see if you have audio. Turn down the level, however, to avoid hurting your hearing. If you have audio with phones then unplug the headphones and it may bring the sound back. If not the jack may need replacing.

Triple Play has good picture, but sound is a loud hum


if you dont have sound in the internal speakers ,or headphone jack if it has one ,try the audio outs to a surround system,if thats what you are using allready,replace the audio cord ,or try a diffrent surround system,most likely if no sound anywhere,the audio output transistor on the main board is toast,panasonic may sell you a schematic,10 bucks or so ,but you will still have to locate it on the board and replace it ,involves soldering,and tech skills,,if you or a friend have these skills it would be worth a shot,if not send for repair,or maybe think about a new tv,the repair could cost as much as the tv depending where you bring it,good luck i hope this helps you aloha from maui todd0708

No sound


Hello monlynne,

You may have a loose solder joint or a problem with the audio processor. I would suggest that you take the unit to a TV repair shop because of the testing that needs to be done. If I were to take a guess I would lean towards an actual problem with the audio output stage (processor).

I hope this helps
Thank you,

Sound off my tv


Hello tennie,

Check your audio out configurations on your TV menu, this includes mute and volume control. After checking them, then try to see if any audio is coming out of the other audio outputs. If there is, then you may have damaged speakers. If there is no audio on any of the outputs you may have a damaged audio output processor or a poor connection in the audio section. If this is an audio circuitry issue; I would suggest that you take the unit to a TV repair shop for an estimate, and let them repair it.

I hope this helps,
Thank you,

No sound,volume bar works


Sorry I dont have a manual but it is available at http://www.servicemanuals.net If you put your ear close to the speaker, with the volume turned up, do you hear any hiss or buzzing? If you dont it could be a bad speaker,headphone jack(if there is one), or the audio output IC or ascoiatated componets. If there is a hiss, then theres a problem with the audio processor or switching IC. If your not a tech, you should not be experimenenting around inside this TV set!

No sound


Check first if theres a speaker cutoff in the menu of the set or the back of the set. Next see if theres a headphone jack and plug in a set of phones to see if you get sound. If you do a connection on the jack is bad. if you put youe ear right next to the speaker and hear a little background noise or a little sound then its probably in the volume control curcuit. if you hear nothing at all its the audio output IC or the speaker itself is defective. Good Luck
