A similar problem was discussed here a while ago, ill quote from there: "This problem may occur when some TV's are connected to a volume control converter. To correct this, decrease the TV's volume until the buzz disappears. Now use the decoder/converter volume control and increase the sound to a comfortable listening level." hope it will help.

I have a Peavey 8600 amplifier. It sounds great but when only operating vocals, in order to get the highs of your voice just right, the speakers put off a large amount of white noise. While singing, you...
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.

Poor picture quality
The problem is probably the convergence power supply.The switching power supply chip on the convergence board will burn out, producing a rounded picture with 3 separate colors. The chip is a long, heat-sinked SIP (single-in-line package) located on the convergence board. You can find replacements on ebay.

I hear background whitenoise/static
You need a better quality connection. Make sure that all of the wires run a straight path without unneeded or unnatural twists or ties. You also need to use the best cables for your situation. This means that you should use the right length and gauge recommended for your devices. If none of this works, you can always get an electronic loop-isolator (sweetwater, radioshack) which is essentially an enexpensive feedback eliminator and does the same thing as a grounded outlet, elimintating all of the extra "electric noise" which is not needed. Make sure that your devices are all plugged into grounded outlets as well. A surge protector with grounded slots will not always work, especially if it is not inserted into a three-prong outlet. Another thing is to make sure that no extra current is running through your devices. Because, in addition to the "noise" you are also damaging your equipment more from such "noise." In fact, depending on how long you have used your equipment, you may have already done some damage.
