    I am having a similar problem right now. My sub powers up and works on and off. It was moved today to another location in the living room clicks on an off when ever it feels like it. I checked all the fuses and they look OK, the whole unit looks mint. Any other items I could check.

    Thanks

Hello,

the only way to get to the fuse:
you need to remove all the screws surrounding the amp on the back of the speaker. when removing the last screw be sure to hold the amp
in place because if you don't it will fall out towards you causing damage to you as well the screw hole.
disconnect the speaker connector. you need to press the latch on the side of the connector to release it from the base.

carefully remove the amp and lay it flat on a sturdy surface. don't lay it on something that can tear because the grill on the amp can damage cloth very easily.

If you look at the board closest to the edge you will see a fuse there as well as on the main board that is lying flat. check those fuses to see if they are burn marks on them. you should have 3 fuses to check. replace as needed with the correct ones. if you don't know which ones you need take them to an electronics store or auto store.
hope this helps.

My mackie swa 1501 when you plug in no power checked the outlet their is power checked power cord good. what can i do


There are many possibilities, the switch, motherboard, electronics etc. If you are a DIY kind of person and you want to try trouble shooting yourself, you need tools. Better still, take it to a service person/ outlet to proper checks.

Plug 110v device in 220v outlet


The capacitor for rectification should in most times defect and rectification diode bridge can be shorted. fuse and maybe also a few fuse resistors
(resistors)
But if primary you cannot measure any resist on a 2 M ohm setting on multimeter on the power cord and its primary broken if you measure nothing between the 2
connector pins ( A transformer example)the powercord should be connected on the right and one of the 2 left points , if then its measure broken try it to solder the left wire of the powercord on the neighbour and try the transformer again BUT IN ANY CASE it should be refused with a temperature fuse similar to those you can find in the transformer when you peel off the covering but there are very thin and weak solderings on the primary winding wire you see connected on the blown tempfuse some of 125 or 127 degrees types are build in . FINALLY for the record regarding CE conformity regarding safety and fire insurance is the case every conceivable things that are here stated to be regarded as an opportunity to find out where the errors are, and it's for safety case to not overlap fuses a jumper, the insurance paid any damages arising from self-recovery therefore represent a warning

There is no power to the speaker, the green light is not showing. We have changed the plug fuse but this was not the problem


If you're talking about a powered subwoofer pluged into an electrical wall outlet check the wall outlet. One of my kids could not get a lamp to turn on in the den. It turned out the outlet was switched off from accross the room by a wall light switch. To check your electric wall outlet, plug in something, like a lamp, fan or a clock and see if it turns on. If not, look for wall light switches and flip them on and off. If it (example fan) dosn't turn on, you have a problem with your house electrical system. Probably right there at that outlet.

Can`t power it up. Connections and fuse OK. Stopped working after switching off and would never switch back on. LED indicator light`s neither green nor red but simply off.


Hi,
First, I have to commend you for having a really fine piece of equipment. Mission makes great products. Now down to business. Being where I am and not being next to your sub-woofer with test instruments and tools I'm going to be so basic as to almost be insulting. However, If I were there, I would be testing these things.
Normally, when one has a catastrophic failure. i.e. no power, and no indication of power present one starts with the power supply. And that starts at the power company.
1st Determine if there is power in the actual outlet that the unit is plugged into. I have found that when installing a sub-woofer on a two plug wall outlet, for example, it might be plugged into a plug intended for a floor lamp. and is turned on and off by a wall switch. Many residences have this feature. It is usually one of the two plugs in an outlet. So you have to test the actual physical outlet. If the outlet is off, check the light switches. If there is no power to the outlet, check the household circuit breaker.
Let's assume that everything works, so far.
The next thing to do is check the internal fuse with a meter. If you don't have one, pick up a multimeter from Radio Shack or Walmart for less than $20.00 or Harbor Freight for less than $7.00
If the fuse looks good but checks out bad (sometime happens) replace it with A FUSE OF THE SAME VALUE. DON'T STICK IN A PIECE OF ALUMINUM FOIL OR BYPASS THE FUNCTION AND PURPOSE OF THE FUSE. The fuse costs a dollar, at the most, the Sub-Woofer costs $800.00 at the most.
OK, so now you have either a working sub-woofer, or an elegant paper weight.
If it is still being a paper weight, contact mission to locate an authorized service company. This piece of equipment in not designed to be user servicable
Here is their link below,
I hope this helps,
Best Regards,
Mark

My home theater speakers make a constant hum whenever my receiver is on. The loudness of the hum changes with the volume control, and goes away entirely when the system is muted. All components are plugged...


jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

I have an infinity sw12 that is for some reason making a high pitched noise and some cracking noises as well. It does seem to work otherwise. I get the same noise when the cable to the stereo is unplugged....


It could be an internal "cold solder joint" however, if your lucky, it may just be dust buildup on the control pods and switches. Radio Shack sells "Tuner Wash" which will clean potentiometers (volume controls) and other electrical contact points. It's an inexpensive "try". Pull the volume and crossover knobs and lightly spray down with the wash. Let it set 10-15 seconds then move the control pod back and forth. Turn it back on and see if it's better. Hope this helps

Power Light off & speaker not working


I had the same problem. The screws around the perimeter of the back plate must be unscrewed and the plate must be pried off as it is glued to the box. When replacing my fuse, 2A 5x20 GMA, it blew the fuse again. Disconnecting the second circuit board prevented the next fuse from blowing, but now the question is what is wrong with the circuit board? I cannot see any damage or shorts.
