Let verify first to narrow down to where the problem can be. First, 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 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. Please post back what you find.

I have a Insignia NS-LCD37 for the past 3-4 years and last night i turned it on and got zero sound. I unplugged it and turned it back on and then the sound worked. then a few hours later I turned it on...


Two options - open it up if you have electronics experience - replace the AV board or trouble shoot the board for bad components. Usually this is hard to do without the proper tools and training. you can check to see if it has busted/bulged/leaking capacitors though...

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.

Insignia NS-LCD37 TV - no sound


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.
