I bought a sharp 23 inc hdtv monitor about a year ago for a really good price. Unfortunately, the internal speakers are horrible. I have tried to hook up computer speakers to  to the audio input on the back, but it doesn't work. The monitor has a headphone jack on the front of the tv, and when I insert the computer speaker jack into the headphone jack, the sound works. But when I do that, there is interference when sound is not coming out of the speakers. I tried looking for a setting on the TV, but there isnt any. Im at my wits end, any advice you all could give would be great.

I could find more info for it if you post the exact model #.

I assume you mean the audio OUTPUT jacks on the back, since the purpose of INPUT jacks would be for playing audio from an external source through the TV's built-in speakers - the exact opposite of what you want to do.

Usually, a pair of audio OUTPUT jacks (one for the left and right channels, respectively) produce low-level signals that are much too weak to directly drive external speakers with. You have to feed them through an external amplifier first (which you can also use to adjust the bass, treble, balance, etc.).

This is the TV, and these are the speakers. You're saying I have to by a receiver to get them to work?

Nope, it looks like your Bose speakers already have a built-in amplifier. So, if you feed 'em a low-level audio signal, you should get plenty of sound out of the speakers.

From the link to your TV:

Other features include DVI-D and HD component video inputs, 720p HDTV compatibility, an analog mini D-Sub 15 pin PC input, an S-video input, a 3.5mm mini stereo audio input, RCA composite audio inputs, and built-in Dolby® speakers.

From the description, it sounds like your TV doesn't have any audio outputs - and that's a problem.

Buying that tv was a huge mistake. Is there anything I can hook up to inputs to get better sound? The speakers now dont sound too bad, but when I turn the tv off, the interference bothers me.

Possibly the reason is the speakers are not shielded for interference like HT speakers are.

What does the interference sound like?  Any chance the speakers or TV is plugged into the same electrical circuit as something else?  (Refrigerator or something big?)

Is it a WHOOM - WHOOM sound at around 60Hz?

If so your screwed.  It's hard to troubleshoot and you may need to find somewhere eles to plug in your stuff.  It's not your grear.

The sound is more of a low buzz that gets louder as I turn up the volume, but then dissapears when I turn the tv on and sound is coming out. The back of the Bose speakers as two sets of red and white plugs, are there any cables I can buy that would hook into the tv and bypass the headphone jack?

Bad ground on something or you have a ground loop fault.  

Trace your path of in/out and remove any logical loops.

That's all I got, I've been drinkin' ALOT tonight.

Actually, just tired.  

Take some pics of the speakers, the connections, and the back of the TV....

You will need to adjust the TV volume and the SPEAKER volume separately - neither one should be maxed out - find a happy medium. try starting w/ tv volume at half whatever the total is, and then adjust the separate speakers (amplified of course) volume at whatever is comfortable. Then you can use the TV remote to adjust tv volume up/down and should still sound ok if you turn it down low or if there is a quiet moment during a show.

check out page E11 - That headphone jack appears to be the ONLY possible way to output sound FROM your tv.  It appears to be more designed as a combo computer monitor & tv rather than just a TV

That was a good find with the PDF instruction manual, I tore my room apart looking for the one that came with the TV. The way my speakers are set up now, the volume level is about 1/5 of maxed, and the TV volume is about 4/5ths maxed. When I adjust it to about half and half, when I turn off the TV to go to sleep, the buzz is VERY noticible. With the volume on the speakers at 1/5th, the sound is only noticible when you get close to it. I will post pictures at some point, but I'm beginning to think it is a lost cause. I bought this tv for $450 from a website that advertised it as a TV with a pc input, so I was thinking it was a good deal. The website was www.woot.com. I dont know if anyone is familiar with it, but they offer one new product a day until it sells out. It was getting ready to sell out, and I pulled the trigger. Wrong decision. Anyway,  after I received the TV and started reading reviews about it, most people were using it primarily as a computer monitor. Thanks everyone for the help, I may bite the bullet and just use it as a big ass monitor.
