    The crackling happens while the tv is on. I can't tell if it is coming form the speakers or from within the unit.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel:The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

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

Continuous crackling from TV speakers


I'm sure you have figured this one out. TV itself is causing the problems.
The circuit board that produces the audio signal seems to be the problem.
Before you call the repairman, go to the web site Shopjimmy.com just to get an idea of what the parts will cost. That way he doesn't rip you off.

I hope I answered your question correctly. Please rate me. :)

Snap, crackle sound from Sanyo TV


It sounds to me as if possibly ya Main IC Amp Chip & OR the Output Capacitors are failing... Sometimes it is a sign of a power supply on it's way out... Either way it's time for a repair shop quote. Either that or it may be the speakers crossovers... to check this, if you can, try another set of speaker... see if problem is still there. If it IS, then it IS most probably as I said above.. If NOT then it may be one or both of the "Crossover Network" in each speaker...
