20 Most Recent Monster Cable MPA 5150 SS Amplifier Questions & Answers

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.

Just a thought here.. What your describing is the symptom of the unit being muted with the remote. Press the remote mute button AFTER you turn down the volume and see if you have normal sound levels.

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.

Is it an input cable or output cable?

Do you have another one you could swap out?

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..

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.

As It was mentioned on the premium post, if after removing the fuse(s) from it, the amp powers up and stays ON; the failure is on the transistors or mosfets and they will need to be replace to get the amp working again on channel 4.
I would suggest to contact the manufacturers to get an authorized repair center to fix it under warranty if your amp is less then a year old.
Good Luck.

the unit is not able to tune above that channel .

means its a failure of components in the control board.

If the display is working, you have audio. Check your amplifier. 1300Watt adaptor ... This unit draws a very low power and that is not needed.

1. Power Off: Turn off the device.
2. Jumper Configuration: Locate the jumper labeled "S16" on the device. Initially, it should be connected to pins 2 and 3.
3. Power On (Alarm+All LEDs Flashing): Turn the device back on. You'll see the alarm LED and all other LEDs flashing.
4. Power Off Again: Turn off the device once more.
5. Jumper Adjustment: Change the jumper configuration from pins 2 and 3 to pins 1 and 2.
6. Finished: Your Porpo YH-2000 is now set to the desired angular unit mode.

If you encounter any issues, you can press the reset switch on the back of the device to reinitialize it.

Are you using the charging cables that came with it? That is a type C. Are you securely attaching the charging cable? A loose connection would keep the battery from charging. If you had a low battery, you would see a red light. That you have no light at all suggests there is no charge left in the battery. I'm not sure the reset will work with no charge which is why you ought to check the cables first. But turn it off and then hold down the Multifunction button for 10 seconds to reset it. Then turn it back on and see what happens. If you can, test the charging cable on aother device. If you have another type C charging cable, try it, just to eliminate a bad cable. If these suggestions don't work, you may try the manufacturer's customer support.

The F2100 remote is not explicitly listed as compatible with the AerialBox T2100, I recommend using the remote that came with your AerialBox T2100 for optimal functionality. If you have any specific compatibility concerns, I suggest reaching out to Dish TV customer support for further assistance.
