Default Sharp Aquos LC-37D7U Speaker...

Hi, this is my first post here and not sure what to do.

Have a Sharp Aquos LC-37D7U that is not even 4 years old yet and in the last month the factory speakers are buzzing and giving off a bunch of distortion.

Since I got it, back in 2005, it was on the Dolby setting with no issues, turned that off to see if that was the problem and it wasn't.

Does anyone have any advice on what I should do to get this working correctly?

For those not familiar with this model, here is a picture:

Thanks in advance for any assistance with this, it is driving me nuts.

Welcome to the forum!

Have you recently changed which outlet you have powering the set? It might be that it is an issue with the outlet having a ground loop issue.

Also try moving the wires that are connected to the display and make sure the power cable is away from the video/audio cables going into the TV. It could be causing the interference.

Hope this helps!

Thanks so much for the welcome and the response!

Nothing has changed. About 6 weeks ago I did add a blu-ray player to the HDMI, but I can't see how that would make the right speaker sound like it is blown out.

I did look in the back and there is a plug that goes into the speaker area from behind, undid it and the left speaker worked alone (sans the distortion). I did put it back in and the distortion obviously came back when that speaker came back on.

I'm guessing it is a blown speaker (I think this model has 2 10" speakers, could be wrong) and not sure if I need to replace the entire speaker section, get it fixed or forego the speaker and get a new speaker set up.

Not really tech savvy, and would appreciate any info or help I can get. Thanks.

PS: funny, as I was looking around online I saw places selling this set that I paid over $3500 for back in 2005 for $1200.00. Bought a sharp because I thought it would last. Was thinking of getting another one, but am tentative at best right now if this can't hold up to light use for less than 4 years.

It sounds like a blown speaker or the circuit that drives the speaker. There is no way to know which is the cause unless you tried swapping them in the TV and see if the distortion changed to the other speaker. It is does, then it is just the speaker that has the issue and a replacement would be fairly cheap I would think.

Of course the better solution would be to get even a cheap HTiB sound system and use that for sound instead. It would give such a better overall experience IMO with both TV channels and even more so with movies on BD.

Hope this helps!

New Sharp LCDs speakers are very amazing the deep bass and less distortion. I really in joy my set, although the wife uses it more than I do. But when I do from S-Video, Component Video, HDMI-Video, RF-Video with OPC is vivid. I am still amazed how the sound quality is.. I guess nothing beats a Sharp!

What is an HTiB? A sound system?

As for repairing it, any recommends if I should contact a Sharp repair place or just go private?

thanks!

HTIB= Home theater in a box. I think you would be better off getting a HTIB, IMO. For the cost of repair you probably can find a decent HTIB and have better sound to boot. I have the Sony sound bar (around $300) and it far exceeds the sound from the TV speakers. Really simple to hook up and you don't even need a receiver. Her is a link for what I use http://www.bestbuy.com/site/olspage....=1206141458600

Thanks for the help and link.

So, do I attach that sound bar to the Sharp? Where does it go?

Currently, I do not have it mounted (this model came with a stand), so should I mount this bar to the wall?

thanks again.

My TV in sitting on a TV stand and I have the sound bar right in front of the TV on the stand. You could also mount it on the wall as it does have the mounting tabs on the back side of the sound bar. My satellite box and DVD player connect into the sound bar module (the box which houses the bass speaker) via HDMI cables, then from the module to the TV via an HDMI cable. Nice easy and slick setup.

It sounds like a way to get much better sound compared to TV speakers, without the wiring, but it should be noted that although much better, it is still short of what you get with individual speakers.

Your soundbar is a very reasonable price, but some decent HTiB systems with a real receiver can be had for only a little more and can be upgraded in pieces as you go along, but for those who will not do the wiring it is a great choice so thanks for posting it.

That is true as this sound bar is only 3.1. But is sounds so much better then the TV speakers and has pretty good bass sound that the speakers can't even produce. Another nice feature is the HDMI switching within the base module so you only need one HDMI cable going to your TV and all your hardware connects to the module and is switched with the remote.

Don't get me wrong. I think that sounds like a great device for so many people who cannot or will not bother with a sound system because they do not want to deal with the speaker wires.

I hope you didn't think i was bashing sound bars. They likely have a very big market of people who would love them, and likely more than would want to go with a HT surround sound system. I was just stating that their is no replacing having a true surround system with speakers placed all around you for the best sound effects.

BTW, the "real receiver" part was in reference to some of the proprietary cheapo HTiB systems that do not have a real receiver that.

Not at all What you say is true as far as sound bars don't sound like a true 5.1/7.1 system but are a night and day difference from the TV speakers.
