These items are not serviceable. If your are electrically minded you could try to find an alternative part But the norm is to replace the whole set up. Or download a suitable software to control through the pre-amp in the computer - www.audacity.com. RealTek97

What r the best settings for a Power Acoustic PEQ-73 7Band passive eq, electronic crossover, sub woofer level control

Depends on your room, speakers being used, size of sub woofer, amp set up ect.
There is no "best setting" for every application. If that was the case a variable control would not be needed.

Some rooms are boomy, which would lead you to turn down low freq's. Some rooms are very splashy, in which case high will need to come come down. Some rooms are very dead in either lows or highs, in which case those freq's would need to be increased.

To get a baseline on what your rooom is like send some pink noise through your system and analyze it with a RTA. (real Time Analizer) There are free apps you can use on your phone or pro audio products that do a very good job. With pink noise being pushed through the system you will see what freqencies are naturally louder or softer in your room. Then you can adjust that real time on your eq and see the changes.

This will set your room to a flat response, however lots of people don't like that sound and want more punch,growl, or clarity. In that case simply adjust the low, mids or highs to your own listening preference

The sub woofer had a distorted sound.

the distorted sound coming out of your sub-w is actually originating from your audio unit, Have your audio unit check for possible repair

Subwoofer is not playing

It is hard to say. The sub-woofer has its own amplifier, although it is supplied the sound data from the main amplifier. It could have a problem with the battery power circuit (Sub-Woofer Amplifier Connector Pin 6, LIGHT GREEN/VIOLET) or it could have a problem with the GROUND circuit (Pin 2, BLACK/LIGHT GREEN) Or it could possibly not be receiving the signal from the main amplifier (Pin 7, BROWN/ORANGE "+"), (Pin 8, RED/BLACK "-"). Or it could be that either the sub-woofer speaker is blown, or the sub-woofer amplifier is defective.
There is also a "High Audio Mute" circuit that connects between the main amplifier and the sub-woofer amplifier.

Power sub woofer is not working on my pioneer vsx-81txv everything is working all the speakers except the power sub connection at the back all i can hear is the hissing sound when i try to connect the sub...

Hissing? How loud? A sub isn't even capable of making high frequency sounds at normal volumes.

The Pioneer manual would tell you how to enable and test the subwoofer output.
Page 17 and the MACCV procedures on Page 33 (auto) or 43 (manual)

configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.

RCA Sub-Woofer

Did you try making sure the subwoofer is turned on under the set up menu on the Sony Receiver?

Press Set Up, Press the left or right button above the scroll wheel until you get to SW. It should say SW: ON or SW: OFF. If it says SW: OFF, use the Scroll wheel to scroll right until it says SW: ON. Also, make sure you aren't in 2CH mode, try A.F.D or surround sound.

Amps and sub-woofer not working

Enter into the Audio Setup mode(press and hold volume button for at least 1 second). Next, repeatedly push the volume button until the display shows "2 ZONE". Make sure this feature is turned off. Hold the volume button again for at least 1 second to leave Audio Setup mode.

Now you need to make sure the Subwoofer Output is turned on. Do this by holding down(AM position) on the control knob(toggle stick) for at least 1 second. Each time the button is pressed, the Subwoofer Output is turned ON/OFF. the display should show "SW ON".

Next, you can go into Audio Control mode(press but do not hold volume button). Keep pressing on the volume knob until "Sub-WLevel" is displayed. Here you can adjust the amount of gain for the Subwoofer ranging from -15 to +15.

I hope this fixes your problem with it.

Cheers
