Yes, I purchased this tv recently and notice a tick after powering down the unit. It lasts about five to ten seconds on this tv. The sound is so awful with the tv's speakers I may take it back to the store. The conversion from my dish hd box seems ok at best. For the money they should provide decent speakers. I have a 1081i samsung from 2002, the speakers are much better. Obviously you have to purchase home theater to go with this unit, more$$$. In many ways my old unit is preferrable. Oh well, can return if I want. Good luck.

Tried mine last night for the first time, makes so much noise that I had to go back to my old unit. Will try again in a different area and see if that helps

Update, I just tried it while playing the ps3 and muted it and there was definitely the same noise. Maybe a bad PSU? Any input would be very appreciated.

Dennis, a hugh pitch noise is indicative of a bad capacitive circuit. It could be something as simple as a power supply problem. You could have a local electronic repairman check the power supply. Remember to backup any videos and delete them and clear settings or passwords you want to protect.{Remember: I'm not responsible for your actions}

It is very sensitive to large dust particles and cold air. It also crackles when any moisture gets in, such as air freshener or Lysol Spray. If it does it often, turn it off and brush off the screen and the power cell and it should stop. :)

No, not normal - Have you checked your wiring, ground, etc? Are the green and blue lights glowing properly? I have two of the surge protectors- One since 2003 and there is no hum... I would return it.... Monster Cable will not honor a warranty by a seller they do not certify. Amazon is certified, but most of the merchants selling the product at a cheaper price are not.

No, I didn't resolve it. I tried 3 different ones, and they all had the same noise. Let me know if you end up going with the same model from a different store, I'm interested to see whether this is a problem with Amazon's batch or the entire line. It's too bad everywhere else is so much more expensive than Amazon though...

The only thing I can think of is to adjust the input settings on your computer's audio settings, or there is a program called Spin It Again, by Acoustica, that cleans pops, crackles and hisses. I hope this will help.

I have a similar issue with my Playstation 3 (which needs to be repaired now) where if it crashes, it would make my LG TV make a high pitched noise until I turn the TV off. I think it's a bug in the HDMI's audio output, or a sign that your PS3 is going bad.

Well some noise is normal and that seems to be what you have going on. If your near a computer or router or any fluorescent lights you will get some EM interference. And that is what it sounds like in your video. You can buy a cheap noise gate and set the threshold to say -75 db and that will clean all that up.

Unfortunately I just saw your post as I was looking for discussions regarding a problem that recently manifest on my 46VL150 from Costco. If in fact your 46V5100 is an identical model I suggest you return it ASAP! My problem is, as many have noted on their sets, the set turns itself off and the red standby light illuminates. No amount of turn off and on resolves the problem. Unplugging it for a protracted period gives you about 15- 20 minutes of "norma" play then the cycle repeats. Cannot comment on Sony repair yet since I am just now calling them. Good luck!

I've had the same exact issue and am exchanging for another pair. They crackle even without being plugged into anything, in my case, though it's often worse when I plug it in.

I have not had that problem. It sounds like a bad power switch or loose connection on the power supply. I would return it and get a replacement if you can. Mine has worked great for several hours of use so far.

I also have the noise coming from the unit. HDMI Passthrough is "ON". Looks like it is a "feature" of a cheap transformer that is installed inside the unit...

I'd send it back if you can--I've had mine for a while and it oscillates just fine with no noise other than WD40 I wouldn't know what to do to it.
