Buzzing sound coming from TV Speakers and any external speakers


Your model has all the audio and video circuits that are all within the Control Box unit which has to be replaced as a unit. You can get one at the following link. You would have to leave them a email as they dont list the polaroid Control boxes, But I know they have one for your model. Just click on the " contact Us" link and let them know the model number they respond quickly.

This is what the control box looks like.1099091.jpg

You could have a power supply failure if the LCD is not turning ON. I have fixed a few of these LCDs with similar failures.

There is a problem with the AV2 input. Since this is a new set, return it for repair or exchange. DO NOT open it up as that would void the warranty.

Samsung LE37M86BDX LCD TV. Just wondering if you had any "optimal" settings for picture and sound etc?? Many Thanks.


If the picture looks good, I wouldn't touch a thing, usually I end up cutting down the brightness a bit with a new set out of the box, and adjusting the contrast to suit my tastes. Sound is probably good as is.

No sound from Phillips 37 LCD


The audio output IC is probably faulty this cost only a few dollars if you replace it your self.Let me know if you need further assistance or more information.

I have a Insignia LCD (ns-lcd19)flat panel TV. I turn it on and the power comes on but I get no picture.


Check unit by shining a flash light into screen to check for image.It sounds like you have a bad inverter board.
