I have had the TV since January of this year and have never heard cracking any noises from the TV.

No cracking sound here, have had it for last 4 month's now. Didnt like the 3d, not clear. Check that as well to make sure it works for you.

Ours kept doing that also. We had it for about 3 years and finally last year it started to the same thing. I took it in to an authorized Panasonic dealer to see if I could get it repaired and I was told that the part that was needed to repair it was no longer available. I hope you have better luck than I did. We no longer have a sound bar for our T.V.

Mine did the same thing before it quit turning on completely. There's a part inside that is failing, and unless you are still under warranty it will cost more to fix it than it will to buy a new one. I ended up having to buy a new, different tv. I wish you luck but unfortunately you are probably going to need to purchase a new tv.

I got a Samsung technician came to my house to fix this crackling noise. He also said he never heard this kind of problems from Samsung before. He changed the power supply, but the crackling persists. He then rescheduled for a new panel. A different technician came with a new panel and replaced it with the one on the tv. Now my tv has much less crackling noise. Maybe one or two pops only, but its manageable for me.

This has not happened when I used mine. Most of my use has been with TV. Good luck in finding a solution to yours. Extraneous noises are very distracting.

Hey Doc, not really answering the question but I'm in the same exact situation as you with the TV. How is yours holding up? Thanks!

I too have the crackling problem and my PNB450 was built also built in January. The crackling happens without the TV actually being on and is totally tied to the temperature fluctuations in my living room. To add insult to injury, I have 1 dead pixel almost smack-dab in the center of the screen. I can't decide whether I want to return it or not, especially since I can't get another PNB450 or the equivalent panasonic (tcp42x1) for the same price. I'm running out of time though, 1 more week. Other than these issues, I like the set in every way. Not sure if it's worth the hassle to return it to Amazon. I too have the crackling problem and my PNB450 was built also built in January.

Does the TV make a clicking sound also? You may want to look in the back first and see if there are any capacitors with cracked tops. If so, this will likely work.

I haven't noticed any hum. The tv has been great. The only complaint I have is the speakers in the tv aren't the greatest but I use a sound bar. If your debating on getting this tv I would personally say do it. It was worth every penny to me.

Have not experienced your issues. No, DO NOT attempt a repair yourself. Please seek a qualified local appliance repair shop. It is normal for metal to "Make Sounds" when heated or cooled. If these "sounds" are new, different, unsafe, or not up to your standards, also consider replacement due to cost of estimated repairs.

I own a Samsung HTL56 DLP model and I'm having problems with noises coming from the TV. It sounds like cracking and poping and it happens when it's on but it's really bad when it's turned off. It sounds like its going to explode. Anyone else have this problem? Can anyone tell me what may cause this? It's only 2 years old. Thanks

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

There is a buzz heard when directly in front of TV at any distance. It is NOT inherent in Plasma technology but specific to this model. To me it is extremely annoying. I heard it during normal programming at normal volumes. It is a design flaw in TV that has not been addressed and it is a total deal breaker for me. Your mileage may very but I'm not listening to that high pitched whiny noise on such an expensive television set.

no. it's not normal. something is loose in the speaker/broken inside, maybe a piece of wood from the speaker and that might be what is moving around. nothing should be moving around inside the speaker box. however, how is the sound? do you hear any crackling? any funny noise? anything out of the ordinary?

Exact same thing happened to me. I am in the process of shipping it out for repair. The unit is of terrible construction and the electronics flaked. I actually got a sub -woofer and wireless surround speakers for my TV which are 10 times better.

What exactly made the sound? Can you inspect every inch of the strip to check for any visual damage? I have ran mine for several hours with no issues.

Is the buzz only through the TV's speakers or is it heard no matter what? I have a soundbar and will shut the TV's speakers off. Im really interested in this TV.
