Insignia NS-LCD37 TV - no sound

Hello,
Today I purchased an Insignia NS-LCD37 TV that was pre-owned. The unit powers on and the picture is quite good, however I cannot seem to get any sound. When I bought it I saw that it powered on and got a good signal, I didn't even think to try the audio. I've tried the obvious - checked that the sound was not muted. I even connect the auxilliary sound output to a portable stereo and can get no sound to come from that either. I did notice in the Menu setup area, I cannot change the MTS setting from MONO to STEREO. The system will not even allow me to scroll to the MTS setting. Any suggestions you have are greatly appreciated.
Thanks - Lee

    Thanks for the quick response. I checked the cables and they all seem fine. I tried the HDMI connection today thinking that perhaps the problem was with the tuner; but still no sound. I may have to return this item.

Start checking the cable connection to receiver, try moving or replacing cables.

If you have a surround with external speakers check surround connection cable and speakers wiring.

If the cables are OK, then the unit may be faulty.

In that case the fault can be either the audio board (often audio circuit is integrated on the main board) , or the sinput output signal board.
Also a contact on connection to internal speakers can give you same problem.

My screen is totally black.


If you still get sound, then the problem can be in the backlight inverter board or in the power supply that supplys the power to the inverter board. Look at those two places.
