Question about Dell Televison & Video

2 Answers

Our Dell TV has a perfect picture but the sound suddenly cut out. We checked all the mute buttons and that is the reason for the soundlessness. Can you fix it

    Ok. I followed Rylee's instructions: mutes off, connections tightened and left TV unplugged for 4 hours (actually about 9). Still no sound. Any suggestions? Many thanks for Rylee's help and any more you may have.

    I think this is beyond me. Will take it in and see about a new A/V board. Thank you.

Is it the same on every channel and while using dvd player or game consoles?
If so, you most likely have a faulty audio card. There are capacitors on these that can burn out. Each capacitor has it's own voltage rating imprinted on them. You can test them with a meter to find the faulty ones.

Hi


Thanks for using FixYa. To start with please check the audio with a DVD player or cable box. Also try using component cables if using a RCA component cable or vice versa. Check that all of the cables are plugged into the back of the TV & MUTE button is not pressed. Do a hard reset by unplugging the power cord for more than 4 hours and power it again, then go into the on-screen-menu and make sure the sap is off and stereo is on. Also try audio from Phone and 3.5mm jacks (if equipped). If this all didn't resolves the issue then it is an Audio IC or bad speakers/speaker connection. Please do accept the solution if the issue is resolved else post a comment for further assistance.


Thanks
Rylee

    I need a translation, I think. I did check that all cables were tight and the mute was off. I will unplug for 4 hours but what do you mean by "sap". I am assuming you mean electricity. I will contact FixYa to let them know if all is resolved or I need additional aid. P.S. I do not have the jacks you mention nor a phone connected at this site.

    SAP is a feature used to change languages in the unit, if yours does not have this then its fine. Please post back for further assistance.

    I may have it but it has never been used. Should I take this TV in to a repair facility? I still have a perfect picture and no sound.

    It seems to be an issue with the internal circuitry of the unit, if you have electrical expertise then start with checking the A/V Board, check for bad connections on this board.

Has a beautiful picture, but all of a sudden there is no sound. It was working one minute and the next it wasn't. I use the cable remote to operate the tv, not the tv remote. What should I do?


Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Restore sound on my Tv, suddenly lost.


  1. Check if the mute button on the cable box/TV/VCR is activated. If so, turn off the mute feature
  2. Verify the volume on the cable box/TV/VCR is not turned all the way down, either by adjusting the volume level on the equipment itself or with the remote control
  3. Check if the TV has an earphone or headphone jack. If so, make sure there are no earphones or headphones plugged into it
  4. Check if the Cable Box/TV/VCR has a SAP/MTS switch (Secondary Audio Program / Multichannel Television Sound). If so, make sure it is set to the proper setting. Consult your TV/VCR manufacturer's user manual for information for your specific TV/VCR. Click here for information on changing this setting on a Cable Box
  5. Check behind ALL TV and equipment (Cable box, TV, VCR, DVD, stereo receivers, etc) and the coax cable at the wall outlet for any loose or damaged connectors
  6. Make sure all equipment and connections are hooked up correctly for the video and audio based on the type of connections being utilized

Have picture and "NO" sound....


Check whether the mute switch is activated by mistake. Check speakers. If there is a head-phone jack check the jack. Try with head phones. If it's ok check the head phone jack contacts inside.

Finally the audio circuit board and its components.

No sound dell 32in tv


These are the answers straight from the dell manual. Ensure that the audio cables are firmly connected to both the audio input connectors on your LCD TV and audio output connectors on your PC or Video player. If on certain TV channels you receive a picture but no sound, this means that you do not have the correct TV system. Modify the SYSTEM setting. Check if TV volume is turn off of muted Connect the audio cable securely Audio cable is connected incorrectly Verify that the audio source is selected correctly in the OSD
