    The speaker that controls the sound on mine isn't working either. It seems to be the heavy cord that connects to the sub has actually weighed down the connector on the small circuit-board inside of the speaker. On mine if I pull up on the connector it completes the circuit and I get sound again.

    I tried to solder the pins behind the connector, but now my cord trick doesn't even work anymore. I'm looking to replace it or find another speaker as we speak.

This has continued to happen to me. Once I even gave up. But then I didn't want to be conquered. I actually took apart the entire assembly, took my time, and redid everything. Wonderful, all is working again. Now this may not be much help without detailed photos, but if you look at the whole shebang carefully and think about it all, you will see where everything is and what you will need to do. I disassembled the connected into tiny little pieces and rebuilt it all. I did this because I REALLY like the sound and the construction of these Yamaha products. I even went ahead and bought two moew new sets of the System 25's on e-bay for $31.31 each including shipping. You got me thinking some more, and I think that I will take the large cord that goes into the connector and either duct tape it to the body or make a connect/cord support to take of the stress on the pins. Good luck.

I have had the same problem with mine. they are far too good a speakers to toss out. I found that dismantling the right speaher box and spraying crc switch cleaner lubricant into the opening in the volume control had a positive effect. It worked for ages, then stuffed up again. another spray and it worked a few months more, etc. Finally though it will not repair it. I guess I could replace the potentiometer if I could find a replacement. Otherwise it may become a mono monitor :-)

I obtained a pair of Yamaha YST MS50 speakers with no subwoofer. Can they be adapted to use a different sub, such as the inexpensive Yamaha YST MSW5? The clear problem is in different cabling.

The speakers will not power up?

if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have made the correct adjustments there

click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can make adjustments there you can also tick in the box place icon in taskbar
hope this helps

Someone gave me a YST-MS50. The left speaker (no controls) does not work. It is not the speaker or the cable from the main unit to that speaker. I find that only 7 of the 8 wires in the 8 pin cable going...

If you don't get it to work would you be willing to sell me the right satellite speaker with the controls? email me: (just take out all the dots)

Will the woofer work without the other two speakers?

There is no point.
The woofer(sub woofer) just delivers the bass. You usually put the sub woofer out of the way under your desk.
Without the other speakers you would just get the thumping bass and no treble

I can't find my adapter (12v yamaha-model-yst-m7) , and I would hate to have to trash them. Can you help?


You will be able to buy yourself a multi-adapter at nearly any electrical store near you.

This is a very handy device, as it has numerous adapter heads, and aperages and voltages you can set it to accommodate the specific device. Go to your nearest electrical store, ask an assitant, and you will be sorted.

Best of all, this cost round about $10, so it is cheap as well.

Hope this can be of help.

Kind regards

Yamaha does it work ??

I have a YST-MS30 myself. Judging by Yamaha's site, the MS50 looks like it's built pretty much the same way. The subwoofer by itself is pretty useless. The power switch and volume controls are built into the right satellite speaker. There is a level control for the subwoofer, but overall system volume is controlled by the satellite speaker. You also need the power supply (15 volts, 1.2 amps for the MS30, but probably different ratings for the MS50 with its higher power).

Actually, it would be possible to open the subwoofer and puzzle out which pins in the connector you would need to jumper together to turn it on, and you might be able to find a suitable power supply. But it seems like more trouble than it's worth. Complete new system with comparable specs are around $100 from online vendors.

Lost the wire that goes from the control speaker cube of my yst-ms50 to the computer audio output. Were can I get a replacement wire? What should I ask for?

you should be able to get a replacement at any computer or electronics store (best buy, radio shack etc.) -

just tell them what you told us - one end (the one going to the speaker) is probably an rca jack while the other (going to the computer) is a standard audio input (3.5mm plug)

Yamaha YST-MS50 speakers to my i Mac.

You can connect the Yamaha YST MS50 speakers to any audio source that relies on a 3.5mm jack. The YST MS50 should have two audio inputs, so you can use one of them to connect the speakers to your computer. If you don't have a 3.5mm male to male cable, then you can buy that at any electronics store or online.
