Samtec Active Sound Speaker Repair
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:

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.

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.
