It sounds like your switch mode power supply panel might be at fault.

Low volume

If it's a new TV, then it might just be as high as it goes. A lot of HDTVs don't come with great speakers due to the small flat feature of the TV not allowing anything better.

You will have to get external speakers for the TV to experience better sound.
Here is a great sound bar that is well priced. http://www.amazon.com/Vizio-VSB205-32-Inch-Theater-Soundbar/dp/B004VGI2EK/ref=sr_1_2?ie=UTF8&qid=1359416740&sr=8-2&keywords=32+inch+sound+bar

I've personally heard that sound bar and they are surprisingly loud and hardly take up any room at all.

WHY DOES MY TV MAKE A LOUD NOISE ON THE SPEAKERS AND CAN NOT HEAR THE VOLUME??

kindly check the terminal connections of each speaker, probably loose or grounded connections, if not, better to check the audio circuit on its PCB board by a technician.

Sound at 50-70 is not that loud. we have another model same size and samsung that is extremely loud at 25.. i dont understand

Speakers sometimes become damaged when going at high levels from low levels and just switching like that..... This may be the cause for it to be kind of low.... Best not to turn it all the way up or it might just blow the speaker fully..... You may have a a volume limit set on it.... Check that, it might be not allowing your speakers to play any louder.... Otherwise, it is best not to have your speakers blaring, just have them kind of low, and your ears will adjust.... People lose hearing when they have their TV's turned all the way up and all loud... Plus it just kind of disrupts the peace of a home :) Good Luck :D

Loud buzzing noise on vizio tv

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Difficulty hearing Samsung LCD tv even with volume up to 100%

Some models are just that way. I would invest in a small surround sound system for them.

Rca l26wd14 buzzing

Hi!

I have seen this before in a lcd tv I worked on! My problem was some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). But also check the signal board (rca s-video etc... inputs). My thought in this was a bad cap was producing a harmonic, causing the speakers to squeal! Good luck, I hope this is helpful!

Continuous crackling from TV speakers

I'm sure you have figured this one out. TV itself is causing the problems.
The circuit board that produces the audio signal seems to be the problem.
Before you call the repairman, go to the web site Shopjimmy.com just to get an idea of what the parts will cost. That way he doesn't rip you off.

I hope I answered your question correctly. Please rate me. :)
