Question about Flat Panel Televisions

2 Answers

Insignia ns-lcd15 Hi I have an Insignia tv with power issue. My tv made a crackling sound through the speaker and powered off now it when I press the power switch the green light comes on but no display. i have tried the flash light trick to see if I see an image but there was none when unit was on. I was woundering if this is an inverter board issue or something more serious wrong. I able to repair it but I cannot find any Schematics for this unit. If I had one it will help out a lot. To determine the problem. I was wounder if any had similar problem and if so how and what did they fix to get it working again? Thank You..

The problem i have seen is the main surface mount IC ( the one with the heat sink) runs hot and the connections go bad from expanding. poor design. somtimes pressing down on the heat sink while its on will yield a picture and then goes out.

I have an insignia ns-lcd15 which I purchased about a year and a half ago and suddenly there was no sound. Occasionally, I get a crackeling noise, but nothing else. Any thoughts?

Audio crackle from any hdmi device plugged in to EITHER HDMI port


Hi, Sounds like bad HDMI cables. I've had this issue myself and you look at the cable and you can't see anything wrong with it but there is internally. My suggestion is to get a new HDMI cable.

We just bought a NS-PDP50HD-09 Insignia 50" plasma


Although we would not be able to assist you with power issue you're having with your TV, I can assure you that the issue with your new HD Insignia TV not turning on has nothing to do with the DISH Network receiver you have connected to it.

I purchased this hdtv new from Best Buy in February 2008. Last week a crackling sound began to develop and now the sound has gone completely, although the picture is fine.


Insignia T.V. 50" Model; NS-PDP50, Plasma T.V.

T.V. comes on, there is sound but no picture.
T.V. is les than 18 months old. We use the T.V. when we come to our Condo in Daytona Beach for vacation, so it hasn't been used very much.

There is no sound on my insignia flat screen what do I do


Try hooking up the powered PC speakers to the AUDIO Line out RCA jacks to see if you get the sound there, if you do, then the problem can be in the power amp section (make sure to check the on screen sound setup menu that the speakers are not set to OFF), if no sound at the RCA jacks either, then the problem can be in the sound processor circuit in the main board.

Insignia NS-LTDVD26 won't turn on


It is always recommended to ensure that your TV is powered down before connecting or disconnecting cables. Unfortunately, it is likely that your TV requires service for the power issue.

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.

TV does not power on. No Stand by light either.


Your power supply is shorted out. Get a good repairman to fix it..."exspensive" repair if you screw it up.
