Good picture,  problem with poor sound
353851
I'll start off by saying the 4661F has a very good picture. No complaints there.

The problem I had is when the volume is turned up, the down firing speakers cause the TV's plastic cabinet to buzz. I did a little research on some Audio/Video forums, and found there were other owners of this particular TV who were experiencing the same problem.

I ended up fixing the problem myself by taking off the rear panel of the TV set. I then intalled small rubber O-rings in the screw holes between the front and rear panels.

Bought this TV to replace an analog TV.  Great picture but sound not that good.  Thin TV leads to thin speakers that do not reproduce sound very well.  Maybe a speaker bar would help.
Amazon had lowest price and delivery was super fast.

Have had the set for about a month connected to Direct TV.  Picture GREAT overall and 3d good.  Had it installed wall mount with center of tv at eye level while sitting.  (Don't know why installers insist on mounting so high. It's not like we're sitting on an aircraft.)  However, the sound from the two small bottom mounted speakers is terrible.  No connection is provided to connect external speakers except through a fiber optic cable to an external amplifier and speakers.  I'd rate this tv 5 stars except for the audio.

The picture quality is just fine once the settings have been dialed in.  It's a fairly cheap TN panel so the viewing angles are not great but if you are around the sweet spot, the picture is bright and the colors look good.  The menu system is a little cumbersome and the remote is fine, not great but not bad either; some button placements are odd and unintuitive but it gets the job done.  The unit starts up a little slowly, taking 20 seconds or so from power on to being able to play a DVD.

The biggest problem by far is the sound.  The speakers are terrible, tinny, and many frequencies produce a resonance with the case that yields an unpleasant buzzing sound.  The sound is so bad that I would not recommend this TV for anything other than headphone usage or very low sound levels that aren't loud enough to buzz the case.

Projector has a great bright picture but sound is not good. You pretty much have to use some sort of external speakers or sound system.

Fantastic movie and the picture is incredible, but the sound mix is far too low.  I don't have a great sound-system, but I shouldn't have to turn the volume up as far as it will go to hear the dialog.  If you have good speakers/mixers, then give it a try.  But for me, the blu ray is almost unwatchable.

Excellent picture, easy to operate controls.  However, the sound is muffled on all settings.  We had better sound from our 28-year-old Zenith.

This picture quality of this TV is excellent!  The 3D is also very good, but I honestly cannot compare it to other 3D TVs since I haven't seen any of those.  The sound leaves a bit to be desired, so if you listen to Pandora thru the TV, you'll be disappointed.  The speakers just don't have the capability to produce good music from them, being that the TV is so thin.

The picture quality is good, considering the price, but the sound is terrible.  You will definitely need to purchase a sound bar or surround sound system with it.  The sound is poor quality and when you increase the sound it never really increases much - it stays fairly loud, even on the lowest volume setting.  As for the picture quality, it's good, but its very difficult to watch shows/movies that are dark.  I would not purchase this TV again.

I put this downstairs in the basement to work out with and noticed the picture is really good, but the sound is really, really bad.  I am looking to get a speaker system for the tv, but still, you should have to buy one.....

This television has a very good picture and enough inputs to allow me to do what I want to be able to do with it. Its main drawback is it has very poor audio quality as I expected. There simply is not enough room in the chassis of the TV to hold decent speakers. But for the price it was worth it.

The size of unit, its features and picture quality are all pluses. The sound is tinny - clearly a negative.

This TV is a great size and has a great picture, and everyone comments on how nice the picture is.  HOWEVER, it has a major problem: the VOLUME constantly varies.  It changes volume almost every time something new comes on (commercials or programs).  I am constantly turning it down so it does not blast me away, then turning it up so I can hear it, and It did this straight out of the box.

I bought this as a second TV and found it online for only $509, free ground shipping, no tax.  The picture is very good, comprable to other LCD TVs priced much higher, but the sound from the built-in speakers is kind of weak.  Plus it doesn't have enough component or hdmi inputs in the back (only one each).  Also I am having minor problems with the TV, including a blue bar across the screen on SD channels that goes away when I switch to an HD channel and back again, as well as sound but no picture when I turn it on sometimes.  I have to turn it off, then on to get it to work.  Overall it was a great bargain, but if you can afford better, buy something else.  One more thing, the remote interferes with my DVD player, when I press the volume up key, it turns on the DVD player.

I got this tv 2 days back but from the movement I switched ON for first time I felt that Sound is not good. I thought it might be some settings so tried changing them but no difference.
Good part is picture quality and mobile remote connectivity.

The picture was good.  However, the sound level decreased significantly during many of the songs.  That's supposed to be the best part!
