Sounds like something may have happened to your tv during shipping. I suggest calling Samsung service and have it looked at. My tv seems to be fine, had it for about a week and a half now. Good luck!

i used to have the bulb version of this tv (was stolen, insurance check is enabling me to get this LED beauty), and it made the same noisesi always suspected it was from heat, just as David Teng is saying....once it's warm enough, it expands and creaks a biti used to find it funny because it would make the cats jump.....never really bothered me :)

I have some similiar experience with the tv. the problem that you are experiencing sounds just like mine. in my case, i suspect the cracking sound is from the left side rear when you are facing the tv. there is a difuser like ventilation outlet on my tv. it sound did like there is excessive amount of heat coming out or something that cause the plastic in that general area to generate a cracking sound. Is this what you are experiencing? have you called samsung and if they provide any resolution to the matter?

Probably thermally induced expansion. Does it also crack after you turn it off?Thermal expansion and contract differences between materials is one of the main causes of failures in electronics.

i have an 47LG90 and it makes a awful loud cracking noise to, every 5min or so and mostly when the set is just turned on or off. LG is very unhelpful with fixing this, had it service and the technician decided to tighten the screws... WOW genius... made the problem worse, loosening the screws seems to have helps some.

have you found out about what the crackling noise is my samsung has the same problem

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

Mine is September 2010 also. What I did last night was pull the TV back out of the box and hook it back up in our room. In complete silence, I can hear a slight noise when the volume level is between 1-2. If I put it on 0, I hear nothing and anything above 2 I hear nothing. This is a gift for my son for Christmas. Once it's actually up in his room and has been used for a couple days I will check it again. What kind of connections are yall using?

i have the same "buzzing" sound coming from the vent on the left rear side. not sure if its normal but im going to set up service call to confirm. *update* ive been tweaking the settings and the buzzing seems to go way down if you put the contrast on about 50%, thus throwing the picture quality off. ive decided im going to send this tv back and replace it with the samsung lcd.

I had the exact same problem with this tv. I eventually just muted the TV speakers and ran the sound exclusively through some external speakers that I have. That solved my problem.

I purchased a Samsung 46 inch Smart TV and it also crackles and pops as it warms up or cools down after it is turned off. Very annoying. I have loosened all the screws in the back, re-tightened them all, even put wd-40 on them, loosened them again, etc. etc. hoping it would ease the problem. No such luck. They use a cheap plastic casing which expands and contracts and the TV warms up or cools down. A brand new TV that costs $1000.00 should not do this! While the picture is great, the cracking makes it to irritating to watch. This weekend the TV is going to be returned. I'm going to try another maker. Samsung, take note.

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

Yes, I too have had problems with the sound - cutting in and out - crackling on some stations. However, this TV is much better since I switched to Direct TV satellite from my local cable system.

It sounds like the tv is defective or the sleep timer is set for 15 mins. Does the tv make any noise or show any pixelation? I've had my tv for over 2+ years and never had a problem with it

I've never had this problem. I would suggest to check your connected wires and make sure nothing is loose. They only issue I've had with the TV is there are parts of the screen now but have no back lighting in the room showing certain colors come on the screen you can see a distortion not in the picture but the back light inside TV but I've had the TV for over 5 years and it does get used a lot I've had problems also with when I would change from ps3 back to the TV there would bea picture but no sound that has happened a few times for or had to do to rectify it was just turn the TV off and turn it back on again sorry I couldn't be more help I've never had this problem.

Best bet is to take the TVs apart - find the bulged out capacitors and replace them with a higher rating capacitor - that's what I did on mine and it has being going strong ever since!There are lots of videos on YouTube about replacing the capacitors, and also a lot of people who have no respect for Samsung because of this issue!

I would first check the cables, whether they are plugged in correctly. Though it may seem silly, check on volume and muting. Go to settings in the TV and make sure the audio is set up correctly. If all other options have failed, You may have a problem with the TV itself. Should be under warranty!

Right out of the box my tv had this problem. I have had it for 3 months and it has buzzed for approximately 5 seconds(until picture becomes visible) every time I turn it on. At first I thought I would be able to deal with it but the more I read about failures down the road, the more I think I am going to return it.

Yes, I am having the same issue with my same model television. Mine was purchased the end of 2/08, it started doing that about a month ago and it is out of warranty. Have you had your repaired? If so, what was the cost? wants $150 just to come out and diagnose the problem.

I had the same problem, the flatscreen LCD TV made a loud crack or pop every few miutes, very annoying.I had a COX HD box (digital cable box from cable company) and had to unplug the box wait about fifteen seconds, then plug it in again. Had several days to weeks until I had to unplug the box again and then plug it in again.The pop was from some static created in the box and passed to the sound unit of the HDTV. Nothing to do with hot plastic.

Mine too, after about a year. Seems to be common for this TV. Mine could not be cost effectively repaired.
