Question about Samsung Televison & Video

LN52A650A1FXZA Samsung LCD. No audio. Audio stopped while watching TV. I did change the cables from the box to the TV, but that didn't help. The power on sound DOES work when TV is turned on.

    Thanks. After rebooting the cable box, the audio came back. Simple solution that I didn't think of. Thanks.

Hello Ed -

You mentioned a "box" so I assume you're using a cable/satellite receiver or digital converter, I would suggest resetting the receiver/converter. Some can be reset by simply switching off and on, some have a reset button and others need to be disconnected from the power supply for a minute or so. Reset the box, then try the TV again. Sometimes the software/firmware in these boxes can crash and re-booting the box will solve the problem.

If you have a DVD/VCR or game system connected to the TV, you should also test whether have audio on the TV from any of these devices. Finally, if the TV has a headphone socket, try plugging in a set of headphones to check for audio.

If you have audio from another device, the problem is likely to be with the "box" rather than the TV. If you have no audio from any device, try restoring the TV settings to the factory defaults by holding down the EXIT key on the Samsung remote until a message appears on screen saying "Resets all settings to the default values". When this message appears, you will need to confirm you want to continue with the reset. You will lose all user settings for video and audio, so you may want to write these down before you reset.

Finally, there is a firmware upgrade for this TV available from Samsung. Please check your current firmware version before installing the update. Click on the link below for the Samsung download page, then click on "Firmware" in blue text. You will need to download both the Upgrade file and the Upgrade guide, which contains the instructions for installing the upgrade:

If you get as far as installing the upgrade and you are not sure how to do it, please let me know and I will be happy to provide detailed instructions.

If you've done all of the above and you still have no audio from any device or headphones, it's likely that the Main / AV board (motherboard) in the TV has failed and will need to be repaired or replaced.

Hope this helps. Please try the suggestions above, then let me know if you need further assistance. You can reply to me by clicking on "Add a Comment" below your question.

I have an audio problem with my TX-SR502.

If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

As I see it this TV has no optical digital audio input. The connection on the rear of the set is "Digital Audio Out (Optical)", not in. I think you need to run a HDMI cable from the cable box to the TV to get digital audio.

Hi my name is Eric,
I hope I can help you with your issue ,
Do you have a cable box?
 First thing i think of is you need to reboot the cable box by unplugging it from AC power, then reconnect it. (then reboot the Tv same way if haven't done that yet either) then its time to try it with AV cables
to make sure the cable box is not bad. using the red/white and yellow cables
then testing with another source like a DVD player, common sense will tell you if its the cable box or the TV.
If you've already done this or don't have a cable box (sorry),

The only thing in the TV that can cause you to lose audio only on TV is the SAP mode.
Hope this helps, if it has solved your issue please click accept
But if you have more questions please respond and I will reply asap

Connecting HT/Cable box to TV?

Get a fiber optic (Toslink Optical) cable to plug into the TV's optical OUT between the red/white RCA audio and the spot where you plug in your cable TV, to the Optical IN on your HT-DS610. This way all audio coming in to your TV from any source goes directly to your hi-fi in all it's splendor.

Have fun!

Aquos Channel Bar/audio bar

There is no factory option to stop the box from poping up every time the signal changes, which is what is happening. It has something to do with signal strength or the fact that your cable box is not set up for HD. Call your cable company to get a tech out to check your signal and set up your cable box because they do not come pre-set with HD defaults.

Audio cut off Samsung 32

Try using different audio connections and see if you have the same trouble... try using RCA cables, optical, and HDMI... see if it happens in either scenario... I would bet dollars that you are using optical audio and the cable is crimped, etc.... you probably just need a new digital optical cable...
