yup i have the same issue apparently its cause of the tv drawing lot of power dur to its fast start up . try plugging it in to the wall direcly ie with no other devices plugged in. i also notice that it only happenes if i have had the tv off for a while eg over nigt and not if it turn it off wait a few mins and turn it on so it must be some thing with the power. i would still call samsung and see whats up.

Same issue from my LN46B750 The speakers were replaced along with the mother board....no help. Still on startup....especially after sitting for a while it will buzz for a few seconds and then go away. Have it plugged into a protected power strip.

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.

i guess calling samsung would be the best thing. maybe it may be a power issue. the tv does suck up a lot of power at start up. but then again 5 seconds is a long time. the tv should not take that long to come on let alone buzz

I totally agree. The buzzing started to occur in late fall for me as well (cold temperatures).

Yes I updated the firmware. It was not hard and it seemed to work. But its been a while since I've done it.

I have not had that occur. I wish I could tell you more about what is causing that noise. It might have done so, but I had mine installed by a professional and I was not there for the testing. I have not had a power failure so it has not had to kick in either, so I haven't heard it in operation.

It's supposed to do it automatically. You may have to reset to OEM settings, then download the latest firmware update for it, depending on how old it is. If you are not comfortable with that, send it back to SPOTs repair and support center listed in the owners manual and give them a detailed letter as to what it is and is not doing. I know of two isolated cases where the owners got newer and improved models, but that is very rare.

Having the same issue with buzzing from left speakers...anybody found a solution yet? was thinking about returning it but realized Amazon only do refunds at this time

It should not be beeping. If it does when you plugged it in for the first time I wonder whether your refrigerator startup surge is triggering it to alarm and start that beeping you are getting. Have you tried to unplug it wait a minute or so and then rep lug it back into the wall outlet before you plug your refrigerator back into it? The only other suggestion is to go to RCA customer service we page and submit a question. Their website page is http://www.rcaaudiovideo.com/support/?kw=PSAPP1R

Did you ever get an answer? Mine appears to be buzzing all the time too - I agree. Extremely annoying.

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

I updated the firmware but the problem persists. I am planning to return it.

"horizontal lines and a buzzing sound" You don't say whether you tried the unit both plugged into the charger and on battery power alone. The buzzing sound might be a symptom of a faulty charger that is not converting 60Hz alternating house current to 5 volt direct current. If both the computer and the charger were healthy, the unit would boot up normally after only a few minutes of charge. My suggestion is to email Wol Vol (you can Google their website to to this) and describe the problem. Wol Vol will almost certainly instruct you to return the unit for exchange or refund; they have an excellent return policy. Joe Gunn

I had this symptom as well and my unit eventually stopped working altogether. I had to return it for warranty replacement and I was charged for return shipping even though the unit failed within 3 months of purchase. Much to my frustration, the buzzing symptom has started on the replacement unit now (only used for 2 months) and I am expecting this unit to fail as well given my experience with the previous unit. I don't know if this is unusual for Speakercraft products, but I will never purchase from them again. At this point, it isn't worth my time or money to ship back the second unit for warranty replacement. I had this symptom as well and my unit eventually stopped working altogether.

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 it has happened only once when I needed a firmware upgrade. I attached it to the computer and logged in to the myharmony website and restarted.

It happened with my LN46a750 also. I purchase from Warehouse Deals for 1308 on DEC 11. Got it DEC 17. ON-OFF started on 19 JAN. Amazon is giving a full refund. I was researching the 650 hoping the On-Off problem was a 750 problem only... DOH!

Make a loud buzzing noise when pressing the button? May need to open it up and clean it. Tutorials on YouTube.

i just installed it yesterday and i do get a slight whistling noise. afe called me back and said to open up the crank case line a little more which is the cause of it, so i'll post back if that ends up resolving it. it's a shame though that customers have to do this to make an unnecessary noise go away.
