My daughters unit had a simular problem. I tooke the cover off the unit and removed discs from the inside. Apperently, she had a homemade disk that the unit did not like and it shut down the whole unit. Once the disks were removed, the unit worked fine. Be sure to check the main fuse first.

    I had a similar problem, not caused by a bad disc. I removed the 4 screws for the top cover of the DVD stack and plugged the unit back in. It came back to life. Kirt

How do I hook up the sub woofer to my home stereo system


You don't say what make or type either of the appliances are, so I can only answer in general terms.
First look at the back of your stereo system and see if there is a dedicated subwoofer output. If there is you should be able to find the correct lead between the two units by looking at both the connections. If the subwoofer is a powered one. IE with a mains plug on it, you have to plug it into the mains before it will work at all. The connection points also then need to be hooked up to the amp. If it's not a powered subwoofer then your main left and right channels speaker wires need to be split into using the subwoofer terminals provided. Another set of terminals on the sub, then lead to the main speakers.
Lastly if it has a dedicated subwoofer output, then the amp might have a setting that turns this on or off. So you might need to switch it on.

Sub woofer not turning on


Is it receiving power? If not that is your answer - could be a blown fuse, bad wire, bad connection, etc.

If power is there and it still does not work then the problem coud be with a bad sub woofer on/off switch, internal fuse, or worse, blown amp from over driving.

YAMAHA AV receiver RX-V861 I have the message 'Vol-fix' appearing on Zone 2 and no sound. This was working fine until then


Setting the RX-V861 remote control to operate Zone 2:
  1. Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
  2. Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
  1. Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
  2. Press the [SET MENU]button on the remote control.
  3. Arrow down to Manual Setup and press the Enter button on the remote control.
  4. Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
  5. Arrow to Speaker Set and press the [ENTER] button on the remote control.
  6. Arrow to the EXTRA SP ASSIGN and select ZONE2
  7. Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
  • Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
  • Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal.
Controlling Zone 2 using the RX-V861 remote control:
  1. If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
  2. You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)

It is possible that a fuse has blown in the sub-woofer box. This unit has the entire amplifier built right into the sub-woofer. It also has a number of fuses in it. I have found that over the years fixing these units that if a fuse is blown you will also have more serious problems in the amp circuit. That is usually why the fuse will blow. They sometimes even have a problem in the main head unit with a digital transistor that is a surface mounted transistor that will cause this problem also. This transistor is part of the turn on circuit that signals the sub-woofer to turn on when the head unit is turned on. None of these problems are an easy fix I am sorry to say.

If you have at least a little experience with electronics and the right tools, like a multimeter and soldering equipment, I may be able to help you figure out the problem. But be aware that these are not easy to fix, and you may spend lots of time trying to figure it out just to find out that you will still need to take it in to a service center and in many cases when somebody tries to fix these type of units and have no experience with them they often cause more problems than they have started with.

For starters you can at least check the fuses, but please be sure to unplug the entire unit from the wall outlet before doing anything, there is a big risk of electrical shock.

The bottom of the sub-woofer has 6 screws in it (If I remember right) and those 6 screws must come out, they are rather big and you must use a number 2 phillips head screwdriver. Then after that you must take out all the screws from around the edges of the black metal panel where the speakers plug in to. When those are all out you can pull the amplifier unit right out of the sub-woofer box. Be careful when you pull it out, you will need to unplug a set of wires to get it all the way out, maybe two sets of wires, I am going off of just my memory right now, but if you need more help I will look up the service manual to help you more.

You will find at least one fuse right near the board where the A/C plug goes to and then you will find a few more fuses on the board that is on the right side while looking at the amp block from the same position you pull it out from and this board is plugged into the bottom board and is vertical but the short side is up and down, the long side is going towards the back of the amp and it is running along the metal chassis on that right side.

I hope this helps you, if you need more help just post your questions here.

No sound nothing


As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will proibably last forever now.

One option is to set the cross over to the sub so it knows when to send the low frequency to the sub and not the front speakers. 120 is a good setting. This can be done either via a know on the sub woofer or the setup screen of the main unit.

good luck
