How do I manage overpowering tv background noise

This is typical of sound systems that come with TVs, especially flat screens. You need to look into purchasing an external sound system, such as a sound bar or a surround sound system. That way you can have better control of background/voice ratios.

No. The reason they give Academy Awards to SoundMixing, is because some do it great, and some do it bad. Once the dvd is printed, there is nothing you can do about the mix of the sound between background and voices. it's just a bad mix. oh well, the same thing happened to me about a week ago, but as the movie went on, the sound mix either got better, or my ears started to tune into the voices better.

Need go to menu screen display and reduce bass to 1/4 level. Do not set more then 40%

A scratchy sound may indicate that your speaker is clipping, or worse, blown. Make sure you are not running too much power to the speaker, or you run the risk of destroying your subwoofer. Reduce the power and see if the scratchy noise has gone away. If not, you may have damaged your voice coils by putting too much power through the speaker.

There is not enough info here to provide a complete answer, but let me give you some background:

There will always be some hiss. This is due to general amplification where a small amount of noise is amplified along with the general signal. In most cases, the signal is strong enough to overpower any noise that is present (vocals in your example). This noise should not be that noticable in normal cases. If there is an automatic gain control in the line, this could account for it as with "silent" times, the gain will automatically be increased potentially to the degree where the noise is noticable.

Barring that scenerio, if the input signal is too low, the overall gain necessary to produce reasonable volume at the speakers will also be such that the noise is noticable. In order to track this down, please provide details about the current setup including:

1) Microphone make and model being used
2) Input being used on the mixer
3) Gain level being used for the mic channel
4) Gain level being used at the master level.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

What is the source you are listening to. 
Try turning off simulated surround sound.

erm,, when you say you cant hear voices clearly. do you mean that they seem to be a little lower in "obviousness" than they should be or are they way down ther as the background level is so much higher.

1. a little lower means you need to bring the trebble up and the bass down and bring up the centre and reduce the surround , this is basically tuning the sytem to your room.
you also need to check the dvd setting for audio out to ensure that the settings for the audio on the dvd are set to 5.1 ( if the little black spare connector is connected to your dvd player) or else set to stereo for "normal " palyback.

2. if the voice is way down compared to background sound track.
are you using an amp for the bass channel, this may need to be turned down. or the thing that looks like a spare connector on the end of the cable going to your cd5 unit is not correctly installed. can you tell me what the set up is.

Your only solution is to change the sound to mono. Eventually the power supply will go and the tv won't work.
