I have the same problem only its the left front speaker. I took my mp 5150 amp to a professional and he told me the problem is a modulator or the MU-1 part. This is a special part on the board that is designed by Monster and no one will have in stock. Each amplifier in this unit has its own MU-1. I am currently waiting further information.

Is it possible to bridge 4 of the channels into 2 Monster MPA 5150 150 watts x 5 power amp


It would not be recommended, as the intent of the amplifier is to drive 5 individual speakers in a home theater setup. Bridging channels on the amp could cause damage and would definitely void your warranty. I would recommend simply not using two of the channels if you are looking to drive 3 speakers instead of 5.

Altec-Lansing VS-2120 speakers problem: Right speaker gives no sound, although computer checks out on other speakers, and headphone plugged into this speaker set works on both channels. Also get static...


try swapping the speakers around if the problem still persists either the speaker is faulty or
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps you

Buzzing static sound in speaker


Static can be caused by a few things.

Does the static persist if you unplug the audio cable from your computer?
If so, the static is being caused by the amplifier built in to your speakers.
If not, the static is probably caused by interference on your sound card. Try plugging the speakers in to a portable media player. You might need to replace the sound card in your computer.

Mpa 5150 continuosly shuts off after around 40 to 45 minutes wiring is good and everything is connected correctly have checked several times what could the problem be


This could be a semiconductor overheating, so when it's left running it acts up. But when cool it plays again. Could be in the power or something that effects all channels. You might be able to find it with Servisol Freezer spray. Wait for the suspect part to heat/act up, then spray it. It should burst into life, when you do so. To be certain apply a soldering iron to it (metal piece). This will cause it to act up quicker, then spray again, to confirm.

Monster MPA 5150SS


Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..

4th channel turns on and then it turns off; 5th channel does not turn on


Hi Alex323a

Nice amps. There is really only one check you can do without getting into the internals of the amp to help you resolve the issue. Disconnect the input and speakers from that channel,and see if it is able to turn on. If are up to it, checking over the poweramp board for that channel for dry or cracked solder joints, and in turn resoldering any you find may fix the problem. If not, the amp will have a problem on that channel and will need a tech to look at it. If it is under warranty still, Monster are pretty good for service I have heard, and they would be your first port of call. Other than that, Call you local HiFi specialist store and see if they can recommend a good audio tech in your area.

Static from right from speaker


The noise is in the pre-amp stages of the Denon AVR. It might be caused by bad capacitors.
