Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

When my tv is playing regular cable the volume doesnt work but when i play a dvd in the dvd player volume comes out of the tv, whats wrong?


Good--sound when playing a DVD means either a setting is wrong and it can be in the set or a box if connected---it also means the audio output circuit is good.

Worst case is where sound is developed by the set's tuner there may be a problem but check all audio settings first---

The volume has went off on my tv. its a samsung le26b450c4w


First verify that the mute is disengaged (toggle the mute button). Second, check the sound configuration to make sure the internal speakers are on, or check the sound output to make sure it is going to the inputs of an external audio amplifier (stereo receiver) and that the external amplifier is working. Try a different input source - perhaps the problem is your cable feed or DVD player.
If the internal speakers are on, the volume is up, and you still don't get any sound from a known-good source (TV channel, DVD player, etc.), then try running the sound to a stereo system as described above.
If that works, you may have a shorted speaker amplifier (depending on the set's design, this may blow a fuse supplying power to both left and right amplifiers or a speaker protection circuit will keep the speakers disconnected). These aren't usually hard to repair, but if you find a blown fuse, fix the amplifier before replacing the fuse or you'll just waste another fuse.

Ok so 1 of my kidos has the RCA 20F420T tv, and i guess there is no headphone jack hole, so i went and bought adapter that plugs into the av jacks, still doesnt work can you please help!!!


Without knowing the specifics on this adapter - I can provide only provide some clues as to how this works.

Basically, the A/V jacks on a TV has a "fixed" audio output level - this means that the sound levels on the A/V jacks is NOT controlled by the volume control of the TV itself. You should be able to set the TV volume to minimum and then use the adapter's volume control to make the earphone / headphone sound louder and softer. Your TV however, may have a setting in the menu that can change the audio from "fixed" to "variable". If set to "variable", when turning the volume down for the TV's built in speakers will also turn the volume down on the A/V jacks as well. You do not want this to work like that as the sound in the headphones and the TV speakers will be same - instead of the TV speakers being off and the headphones on.

I hope this helps and good luck! Please rate my reply. Thanks!

My volume just went out on my NS-LCD32. it worked fine this am but when i just got home it went out. i have tried evertyhing i know on trying to reset the tv and regain my volume. cant you give any...


My sound goes out on one station and none of the others. The only to get the sound back is to shut the TV off and then turn it back on. I suspect something was pressed on the remote, but I can't figure it out.

The sound has quite working


First, NEVER turn the volume all the way up to see what's wrong. If HALF volume doesn't work you're only risking a catastrophic speaker blowout if you should suddenly flick the switch that's causing the problem with FULL volume on.

Look for the MUTE or Volume +/- controls on the remote and indicators.

LG TV 32LB9D VOLUME STUCK AT 100, NO RESPONSE TO REMOTES


The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.

Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.
