No audio at all and buzz in the speaker output.

Well the subject line summarizes the problem. Everything works but there is no audio anywhere to be found on the main board but the power amps work fine.

I checked my speakers there not blown out still making buzzing sound. Why?

the buzzing sound is an symptom or indication that there is a defect on the output audio system from your unit. A good audio system does not give out a buzzing sound.
Check for shorted audio wire coming from your audio unit going to the speakers

Is there a way to reset the radio to factory settings

I don't really think resetting the radio will help. You may want to check all of your speakers and speaker wiring. If you have any shorts and/or grounds it will affect your audio. The beep is coming from inside of the radio itself. If all your speakers and speaker wires check out good, you may have a bad internal output ic.

I have a hp w19b moniter and everything is hooked up even the speakers. However the speakers have yet to work. I have made sure there plugged in and everything.

The speakers in this monitor require a powered speaker output, and most audio cards only provide a line level output, which is not enough to drive these.
You may need to go out and get another sound card like a creative labs or the like - but make sure the card has a SPEAKER out on it, and not just a line level output.
You may be better off simply going out and getting a set of powered speakers!

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

No sound,volume bar works

Sorry I dont have a manual but it is available at http://www.servicemanuals.net If you put your ear close to the speaker, with the volume turned up, do you hear any hiss or buzzing? If you dont it could be a bad speaker,headphone jack(if there is one), or the audio output IC or ascoiatated componets. If there is a hiss, then theres a problem with the audio processor or switching IC. If your not a tech, you should not be experimenenting around inside this TV set!
