Boston Acoustics MCS 130 LCR Main / Stereo Speaker - Answered Questions & Fixed issues


mine had the same problem until it completely quit. unplug the sub and turn it over, press gently on the speaker cone, does it move freely, or do you hear a sort of scrapping noise? if it moves freely with no noise, its a dif problem than mine. if you do hear the scrapping noise, then theres a short in the voice coil, from what ive read you have to replace the driver (actual speaker part), its basically blown

You may have to replace the zener with an equivalent having a heftier current rating.

donaldws1018 I was wondering if the static problem was resolved yet. I have a pair of the VR970's that don't sound so good either.

I don't know if you will see this or not, your post was 2 years ago. I have the same problem. My volume is stuck at 24. I have tried soft-reset........among other things. One thread says to turn volume down to 00 then press for 10 seconds. I have no control over the volume, so, yeah, thanks for that fix. I found that I could get the volume down by unplugging it,plugging it back in and sometimes the volume would pop up and I could turn it down one notch. I did it till I got to 00.............thought AHA! My problem is solved! No such luck. When I press the volume at 00 and try to hold it for 10 seconds, after 3-5 seconds it just pops back to the station frequency. I also thought that if I could get into the guts and spray the volume control with tuner-cleaner, it might help. No go.......after taking off the cover, I found a bunch of REALLY delicate looking electrical tapes and wires..........I was scared I would destroy something in an attempt to reach the volume control. I hate to trash this radio, the sound is awesome...............great design on the speaker, NASTY design on the controls. I'd be VERY interested to know if anyone, anywhere, has found a fix for this. I think maybe my next step will be hitting it with a hammer.

Most often this unit goes dead because of zener diode ZD3 shorting. It is a 18v zener. replace this and you should be back in business.

there should be panels or rubber feet with screws underneath. or the speaker part can come off. that would be where the mesh would be or holes for the sound to escape.

Fuses blow when there is an overload. The most likely cause is a short-circuited semi-conductor IE: a transistor or IC etc. If you find one of these devices inside it with a heat sink on it, that will be the most likely cause. Transistors can be tested with an Ohm Meter and in a short circuit fault such as this, it will be like you have put the two test probes together!

Short circuited component/s at its circuit board. Check and replace it. Check for shorted component/s at the amplifier stage circuit. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

When you are listening to the radio or anything else for that matter, use the mode dial to select info. From there it should display the radio station or whatever input you are in, rotate the mode dial again and it should display the time, once it does, select that by pressing the mode button.
