I think I have solved the problem. I dusted the tv completely. Then took the cable box and with a hair dryer in the cool setting blew out the interior circuits to try to remove all dust. Turned the set on no more crackling. Thanks for the posting.

First of all, sorry for the mix up on model the model #. I was viewing a problem regarding LG LCD TVs and found your link. My problem is with an LG 42LGX LCD HDTV. It has worked fine without any issues...


Hi,

welcome to fixya and thank you choosing my service..

OK,that is the most and common problem of all LCD TV...

Usually dim and totally have no back-light is cause of bad inverter board.One of the inverter board is shorted that cause dim light and crackling sounds..

This are the sample images of inverter board.
1_22_2012_1_29_43_am.jpg

to make sure that the problem is on the inverter board kindly try to disconnect/unplug it from your TV and power ON then observe if the crackling sounds remain or not..If the crackling sounds gone replaced the inverter board..Also I need to how many inverter board you have? if 2 or more disconnect it one by one to determine if where is the specific faulty inverter board..

Example:
I disconnect #1 inverter still have crackling sounds..next disconnect #2 inverter and reconnect the #1 inverter until you found the faulty one..Note when you doing this make it sure you power off the TV before you unplug or disconnect inverter board because its high voltage..

I need the picture your TV screen..just send it to chesterpendilton@yahoo.com

Regards.
Chester

My 37" TV


if the set has a headphone socket try that with some headphones if noise vanishes then is probably a loose speaker nacelle if noise is in headphones this is a set issue check all connections are good my set occasionally gets a loose hdmi connection this affects the sound badly.

WHEN I TURN ON THE TV ITS MAKES A VERY LOUD CRACKLING NOISE.


If you have lost your freeview channels & your picture has been breaking up (pixelating / freezing) etc as well as crackle on the audio, then I would suspect you check your antenna, it could be your incoming signal is weak which would give you these problems.

Crackling noise from tv


That crackling noise has nothing to do with the television and everything to do with your antenna. It is merely signal breakdown, when you get signal interference with analogue tv you get snow, with digital you get little squares on the screen and/or sound breaking and cutting in and out, get a licensed antenna repairer to come out check your signal strength as you may need a booster or your antenna could just be a few degrees off....
