This woofer is from my parish, it simply stopped working, no sound at all..
In detail it’s a 180W RMS (EIAJ), active; nothing to say, it does (did) its job.

Let’s start wander around a little..

The back has many screws, only six holding the case together.
DO NOT REMOVE THE INNER SCREWS: they are holding other internal components.

(Remove the circled screws)

When opening, take care, there are wires connecting to the speaker.

First, I checked if the speaker was fine simply connecting the speaker to my mp3 player. I used an adapter as you can see:

To check the speaker grab one of the coaxial from the player and connect it to the speaker wires: one wire to the inner pin, the other to the outer ring.

Rocket science method…

SOUND! MUSIC! And very loud, my old mp3 player made me proud of it..

So.. the speaker was good, I was hoping in just a broken wire, easy to fix, but this was not the case.
Time to look closer to the board, starting from connectors, switches an sockets (anything that can be messed up from the outside).

It wasn’t a long search, the soldering between the board and the level knob was broken:

Noobs mishandling the woofer I bet…

A few minutes of soldering and the problem was solved:

Good thing my grandma teached me how to solder at the age of 10 :D
Cheers!

Today’s fix: Braun 3773
It’s an electric shaver with internal battery.

The battery, a good Ni-Mh AA, avoid the need for the deadweight as used to be in the previous model and it last very long.

The problem is a broken clip that should hang the head, so I need to keep it in place with a finger while shaving.

You can see the broken clip doesn’t come out in the “lock” position (right photo).

Here’s how i fixed it:

1 - I took the head off

2 - Unscrew the 3 screws: 2 under the head, 1 at the bottom

3 - I forgot to unhook the rubber protection between the two sides of the shaver, here how to do it correctly.

Here’s the broken pin. The spring cannot work.

There is some space for the clip to go back when it’s pushed, that’s where I put some filler to keep it hooking the head.

4 - I cut a foam peanut for the filler (it’s not a peanut, it’s a cube, but you get the idea)

5 - A little glue to keep it in place.

6 - Here we go! I’m going to shave now!
