This can happen if you hook an external amp to the audio output jacks on the TV and those jacks are set to fixed output, but I will assume that you are talking about the sound through the TV's internal speakers. If the picture is normal and the On Screen Display (OSD) shows that volume is being turned down then the microprocessor is putting out the correct clock and data commands. You need to find the audio processor IC which controls the volume, tone, balance, etc. and see if the clock and data information is actually reaching that IC. If it is then I will bet that the IC is defective and needs to be replaced. If you do not have an oscilloscope or experience in repairing PC boards then have a qualified tech handle it for you.

The volume on my 32 Insignia flatscreen TV suddenly went to max volume and wouldn't go down, both on the remote and the TV


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.

My t v has no volume


Do you see the volume indicator moving when you press the vol up/down?

Could the internal TV speakers have been turned off? This is done when using a sound bar or a AVR (Audio Video Receiver) aka Home theater

Volume is gone (except for a clicking noise)


Check whether the mute function is ON or not. If not, the muting section circuit inside has the fault.

HOOKED ALL MY SPEAKERS UP BUT SUB AND CANT GET ANY SOUND FROM FM OR TV THAT I HAVE HOOKED UP AM I MISSING SOMETHING ALSO THERE IS A LIGHT THAT SAYS SOUND MUTE BY FM


From the remote control ONLY:

Press MUTING to mute the sound through all

speakers and headphones connected.

"MUTING" appears on the display and the

volume turns off (the volume level indicator goes

off).

To restore the sound, press MUTING again so that "OFF" appears

on the display.

• Turning MASTER VOLUME on the front panel or pressing
VOLUME +/- on the remote control also restores the sound.

How do I turn off the tv speakers so that I may use surround sound?


Depending on the model TV, there may be a switch on the back to turn the speakers off, or there may a choice on the audio on-screen menu to turn them off. Not all sets allow you to turn the speakers off, but you can always mute the sound, although this sometimes leaves the word "MUTE" on the screen to remind you. You can also just turn the volume all the way down on the TV. If you're using the AV inputs on the TV with a device like a DVD player, another option is to connect the video only to the TV, and feed the audio to the amplifier providing surround sound. Then the TV speakers won't be used at all.

My view sonic monitor has no sound


Troubleshooting Sound Issues Verify that the audio cable is connected to the AUDIO OUT or LINE OUT output on the Sound Card and plugged into the AUDIO IN or LINE IN of the Monitor.   Make sure there are no cables connected to the Headphone Jack (located next to the AUDIO IN port) on the monitor. If there is, please disconnect that cable and try the speakers again. Connecting a cable to the Headphone Jack disables the speakers. If there is no cable connected into the Headphone Jack, test a pair of headphones into that jack to see if you can hear sound out of the headphones. If you are able to hear sound out of the headphones, disconnect the headphones and try the speakers again.   Verify that the Mute on the monitor is not on or the Volume is not turned down.    Verify that the Mute on the computer is not on or the Volume is not turned down.<    If there is still no audio from the monitor's speakers, connect the Audio cable to another audio source like a portable CD player or tape player headphone output. If audio can be heard through the monitor's speakers, then there may be an issue with the computers sound card.    Connect another set of computer speakers (if available) or headphones to the AUDIO OUT or LINE OUT output on the Sound Card. If NO audio can be heard then there is an issue with the sound card. Verify with the computer's manufacturer for additional assistance.   LCD TVs Troubleshooting No Sound from a LCD TV No Sound when using RGB (when connected to a PC) Confirm the audio cable is plugged into the Audio in on the LCD TV and the audio out on the computer.

The N1700w is designed to take a 1.0v RMS audio signal for optimal sound quality.   Confirm that both the LCD TV Mute and Windows Mute are off. A general message will be displayed on screen to indicate status of Mute (On or Off).   Press the Volume Up Button on the monitor or remote to confirm the Volume is not set to zero.   Confirm that PC volume is sufficient by using Windows/Macintosh Volume adjustment settings.   Try plugging another audio source such as a CD or Cassette Player directly into the Audio port on the LCD TV to confirm the speakers work, or try plugging headphones or external speakers into the sound card on the Computer. If the Headphones or External Speakers do not work, contact the manufacturer of your Computer for further support. No Sound when using S-Video/Composite/ Component Video Confirm the audio cable is plugged into the Audio in on the LCD TV and the audio out on the S-Video, Composite, or Component Video device.   Confirm Mute is off. A general message will be displayed on screen to indicate status of Mute (On or Off).   Press the Volume Up Button on the LCD TV or Remote to confirm the Volume is not set to zero.   Try plugging headphones or external speakers into the audio port on the S-Video, Composite, or Component Video device. If the Headphones or External Speakers do not work, contact the manufacturer of your S-Video, Composite, or Component Video device.   Note: Some ViewSonic monitors do not include speakers.

"muting" shows up the screen and I no longer get volume, can not the muting off as I can not see where I would change that setting.


Are you sure it's not the TV telling you that it's muted? I went down the tubes on that one myself.

The receiver's Mute can be defeated by just rotating the volume knob upward. Ditto with TV's.
