I have a Samsung LE40B650T2 - no sound direct from the TV


It sounds that the sound processing section [digital circuts] are working well, and the fault must be either to the speakers, settings or to analogue audio amplifier section. Make sure that the Mute function is OFF. If it is OFF, and still you do not get audio output by tV speakers, surely the fault must be to audio amplifier circuits, provided speakers are OK. If your TV has a headphone out socket, this socket should also checked for proper interconnection.

It sounds like you left the tv set's internal speakers on after hooking up the sound bar.You should turn off your internal speakers via the Menu on the on screen display and go to audio. There you should find something about the speakers (on/off). Turn off your internal speakers and enjoy the sound bars great sound.

Terrible sound, sounds like speaker blown. Got it 2 days ago.


If this is a "new to you" TV, keep reading. If it is a brand new TV, I'd be on the phone to the store to have a replacement ready for delivery / pick up. You do not want to be repairing a TV that is 2 days old.

The first thing to do is determine if the distortion is coming from the speaker or if it is on the signal going into the speaker. Do both speakers sound distorted or only one?

You didn't include the model number of your TV, so I can't speak to specifics. Look for a terminal on the rear of the set identified as "speaker" or "external speaker". If provided, there will be one set of terminals marked for the left and one for the right external speaker.

Connect a speaker directly to the terminals marked for either the left or right speaker (connect to the one that sounds distorted if only one of the built in speakers works correctly - other wise pick either speaker terminal pair.). Speakers that have RCA plugs on them, have built in amplifiers, require batteries or or to be plugged in to an outlet should not be connected here.

Alternatively, you could connect a pair of stereo headphones or earplugs if your TV offers a jack for them. It would have a headphone icon or say "phones" above the jack if one is provided.

Once connected, turn the TV on, lower the volume and set the TV to enable the external speakers / disable the internal speakers. This may be done via menu item selection or a small switch near the speaker terminals. Slowly increase the volume to listen to the quality or clarity of the sound coming from the speakers you connected. If they sound distorted, the problem lies with the audio amplifier in the TV. If they sound OK, then there is a problem with the speakers in the TV.

If you can't return the TV, you may have to see about using the left and right audio line out or HDMI jacks to send the audio to an external amplifier and speakers to hear the program.

I hope this was helpful and good luck! Please rate my reply. Thank you.

The sound goes off intermittently


Forget Sharp's defective speakers. Connect your sound output to powered stereo speakers and disable the internal speakers (look through the TV's menu). The operator's manual explains how to disable the internal speakers. You'll be able to control the sound normally (mute, volume) with a remote control.
I connected my stereo output (2 RCA plugs) to an old boom-box and I get better sound than with Sharp's built-in speakers.

Speakers Shot?


Technically, the television should protect itself from doing any damage, but sometimes that doesn't happen correctly.
When you say that they sound like the speakers are blown, can you describe that sound?
If it sounds like they're blown, they likely are.  It's probably about the same cost to repair the speakers (if out of warranty), than to buy an external amp and speakers.

Crap sound from swisstec 19" LCD TV


you could try the scart socket for audio out ,it could be worth a try.
A scart to phono adaptor would let you connect to your amplified spaekers but would only give a fixed audio level,
ie you could not adjust the sound via the tv remote control
be careful if you connect any speakers to the tvs speakers you could damage the audio op stage on the tv ,

No sound coming through tv speakers


Hi.

Some Large flat panel tv sets have seperate speakers that clip on to the side of tv set if you got the manual with the tv does it say about seperate speakers.
Or if it does have speakers with the tv set check that the audio frequency is set to your countries transmission frequency.
Example UK is PAL (I) If your not in uk try and find out what yours is.
