Check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit which you will need new main board. Please post back what you find.

Two things to do:

First see if you have sound with a DVD etc connected to a rear input.

Second look in the menu to make sure speakers not switched off or to external

I have a Sharp LC37D43U TV that has no audio. The volume indicator shows can be moved up or down but no sound comes through the speakers. The picture works fine. I have nothing else connected to the TV....


It appears you ve discovered the sound task levers required to adjustment properties. Your Tv can still move levers even when the volume is set to mute. Select the unmute button before any voice or audio would be reactivated. Assuming that seting the TV on mute has predominant integrety over the volume functions where not unmuting usually with the same button on the remote would not achieve accessibility to the volume functions. refer to the TV user guide for diagnostic audios. Good luck

No audio


went into setup, tv and kept hitting the mute then unmute it finally took. Not sure what was wrong with it since I had already done that several times. The two audio outputs on the side of the tv do not work like it says in the manual for surround sound. Its definitely a cheap tv.

No volume on my Samsung 50" flat screen


Go check up the settings. First disconnect all appliances and then reconnect when power off. Configure connection when power on.
See your manual. You use the analog tuner or digital cable or satelte receiver to watch TV. If external digital decoder check your settings there. They are independend and might be low or muted sound level or incorrect setting.

Samsung LCD tv wont turn on


what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

pls rate me!
