Samtec Active Sound Speaker Repair

By Jestine Yong on October 8, 2016

Hi,

Today I got a Samtec active sound speaker system to repair from one of my customer. The main reason was the sound system would not power on.

Actually there is some noise but the unit is not powered on even if the noise is there. Here is the unit:

I took the back panel down which is bolted on with six bolt’s. After that I saw this:

I can say, I’m not impressed with this unit. All around are messed up with some sticky stuff and the pcb are very low quality, the connectors are bonded together with some sort of glue etc.

A really pain in the …

Let’s see closer the pcb:

What the hack is this alien stuff on the soldering side of the connector???

The whole connector is broken. The factory where this unit was made they destroyed the soldering pads for the connector. Then they tried to solder somehow the connector just for testing purpose. Then they took some sort of glue and made that alien stuff.

On this unit, there are no one soldering pad are fine, all around are unsoldered or broken pads. I had to resolder many of them and of course made the connection with the wires and the connector.

Here is how I made all that connection again, but I eliminated the connector.

After this hacking, digging, scratching etc. the unit powered on and played my favorite songs for a while. But here is the most important label on the unit:

I hope you would never get for repairing purpose this unit, even if you wish to buy this crap please don’t do that. I saved this junk from junk because of the environmental ethic in me but this is really for recycling only…

I hope you enjoy this tutorial and will save lot of repair time.

Christian Robert,

Good Job!
This could have easily done on the same damaged tracks without direct connection; with making loop at one end of the wire.for reference just follow the Link it may helpful in future repair work.( if any instance wire get disconnected from the point of the solder then it is difficult to identify where this wire has located).

  Thank's for this link.
  I never saw a tutorial like on that site.
  Very handy tutorial.
  At the moment when I saw what is going on
  on that pcb I didn't thought to repair it,
  I searched for my sledge hammer.
  To solder just the wires to the places where they
  belong and closing the unit was my only target.
  Thank you because you support my article.
  My best regards.

Hi Christian, the sticky parts and the low quality 'paper made' PC boards are always a pain in the b.t. (LOL).

My compliment to you for taking this job! I would it scrapped the thing for parts. Never heard of that brand. But it seems that someone else worked on it before you did.. But I am glad you took it seriously and save the unit. Hope yo got paid good for saving this unit. Like the last comment "feel the difference!" hahaha.. take care friend!

Good Job Christian. when you see crappy workmanship like these... you wonder what really is going through people's mind when they design and build these things.
