A7 front panel removed
I love my Adam A7 monitors, but they have a known issue with the power switches ‘locking’ in the on or off position. This happened to me and the fuse also blew. I know this is a simple repair, but I thought I’d browse the web and see if anyone has explained how to do it. I found nothing except some somewhat poor videos on the topic.
So I’m going to walk you through the process step-by-step.

- Remove switch
- Replace fuse

What you need
The tools that you need
Here’s the supplies that you need:
- Hobby knife with a sharp blade (no 11)
- Some sort of clippers, even nail clippers will work fine.
- Round 10a 127v Rocker switch
- Flathead screw driver, small and thin tip if possible
- FUSE - 5mm x 20mm 127v 2amp slow-blow fuse.
Unscrew the front assembly
UNPLUG THE MONITORS FIRST
The first part is simple, just unscrew the 4 screws on the front assembly and gently pull it out. Be careful to not disconnect any wires to the volume control.
Clip the zip tie
If there’s a zip tie, remove it.
Remove heat shrink
Use your hobby knife to carefully cut a line down so that you can expose the wires, but do not yet remove the material! Just cut it as in the image to mostly unbundle the wires.
Remove the goop
Now carefully cut around the switch, as close as you can to the faceplate. Don’t worry about cutting in to the switch. You want to cut away as much of the goop and heat shrink as you can.
You DO need to be careful of the LED. I removed mine while working on this, and put it back with some tape after. Just be careful and think before you do things.
Clip the switch
This isn’t 100% necessary, but it makes life a lot easier. Look at the switch and on the top/bottom you will see some arms. Cut them or clip them. These support the part that holds the switch in place, and cutting them makes it much easier to remove the switch.
Remove the switch
The easiest way I’ve seen to remove the switch is to press the switch arms (near what we just cut) and simultaneously CAREFULLY push a flathead screwdriver under the skirt of the switch. Switch the screw driver (do not try to lever it upwards).
Work slowly and try not to scratch the faceplate.
This takes some effort, but if you are careful and work slowly it will work out just fine.
Test the switch!
Test the switch. Make sure it works! I checked before with a multimeter, and checked with power on. BE CAREFUL Do not let any metal contacts touch each other, and do not touch anything! You will get shocked if you bridge the switch leads. Ask me how I know, twice.
You don’t want to be digging out your replacement switch because you got a bad switch. Test it before you re-assemble.
If it doesn’t turn on, make sure you check the fuse. My A7s fuse blew when my switch broke as well.
Put it together
|Re-assemble the switch and make sure you put it in the correct orientation. All A7s that I’ve seen have the ‘power on’ (the||or closed dot) on the top. The cables can be put on in any order, there’s no ‘right cable’ for either switch contact.|
Once again, you don’t want to be digging out a switch because you put it in wrong. That’s no fun.
That’s it! Screw it back in and you’re done.
If your A7s do not turn on at all, and you are 100% sure the power switch is functional, then check the fuse.
Simply place a flathead screwdriver in the notch under the power jack and pop out the fuse holder.
Just pull the fuse out of the holder and replace with a 5mm x 20mm 127v 2amp slow-blow fuse. It’s probably worth buying some extras if you plan on having your A7s for a while.
That’s it. This repair should take about 15 minutes total. The hardest part is removing the original round rocker switch. Be patient and with every move you make, think of the worst possible outcome. If you think you may scratch the front plate or smash a tool in to your hand then STOP. Try something else.
REMINDER. Do not touch the switch leads while it’s plugged in. Don’t let them touch anything else either. I blew the Zero-Ohm Link on one of my monitors doing that, because I’m an idiot. (I unplugged the wrong cord. Always unplug at the equipment, not the power source if you can!).
