No sound on lcd tv


First check your TV setup menu to see if your TV audio preferences are set to PC audio. That is a setting that sends audio out through your PC cables instead of the TV speakers. It may also have been set to mute through a remote.

I have a samsung HL72A650C1F DLP ,no sound beautiful picture


DLP systems (of all makes and models) have not proven very reliable and the repair and maintenance costs are high; but that is the price one must pay for such wonderful technology and picture quality. But, your picture is working good so that is positive. The loss of sound in most cases is in the settings. Suggest you go back and reset all the settings pertaining to sound or audio. Make sure SAP is off (if you have that setting) and the speaker setting is correct for your system (internal if you are using the speakers in the set, external if you are using external amp/speakers) and the cables are all in the right place, etc. If all checks out ok then chances are the problem is internal to the set. Could be the amplifier is defective, but when all channels are dead it is mostly a problem inside the power supply. Repair is needed in this case, sorry to say.

No sound at all ,good picture ,mute is not on


If using a box make sure sound not turned down on it.

In Set menu make sure speakers are switched ON.

Look for a slide switch on rear of set for Internal/external speakers. It may also be in set's menu as an option.

If ear put right to speaker"s do you hear anything?

still not working likely an audio output circuit problem.

No sound 72 inch samsung


Some simple things you may already have tried but I will list:

Unplug set for a while and then plug back and see if sound--when unplugged the set may reset.

In main menu make sure speakers are not switched off.

I doubt it is mute but if also using some type of box check that its volume is not all the way down.

If internal speakers put your ear right to them---hear low sound or a buzz or hum?

If using external speakers of any kind look at the hookup and switch to make sure internal/external is correctly selected

If NONE of these help you have an audio problem and should first contact Samsung (yes it takes time on the phone) to inquire if some common issue or a possible software upgrade is available for this.

Last: Some failure has occurred either in the audio circuit or something that feeds it.

IBM thinkpad type 2647 - after installing external


Go to control panel / sounds / audio, and see if the boxes have greyed out writing, if so then the driver needs reloading, if they are all good check all settings.

Meant to ask if volume control icon is showing in the right lower task bar.

Distored sound


distorted sound from external speakers or internal speakers?
isolate please. remove external speakers if you have one. just troubleshoot on the internal speakers alone.
uninstall the audio drivers. install the latest one. if fails. download then flashed the latest bios.
run diagnostics extended test to check the internal speakers. if also fails then replace the internal speakers.

No volume


On the back of your set there are 2 switches that tell the tv whether you are using the internal speakers or the external speakers.
Make sure the switches are set to internal so the speakers in the TV receive the sound signals. If they're set to internal maybe the internal speakers are bad. Set the switches to external and hook up external speakers to the speaker terminals on the back of the TV. If neither setup works then it sounds like an output transistor or related parts.

Toshiba 32 in. model cf32c50


Good day.

Please check if your internal speakers are busted. Trying out the external speakers are good isolation to the problem thats why, you can pinpoint the problem to be in the audio section.

No Sound on TV??


I would borrow a set of external speakers to see if I could get sound from the sound circuit at all, if not, then it sounds like the repair shop.
