Where I work we have a korg ms2000 synth and it died. It is 17 years old and the DSP chip died. It started making a grainy distorted sound when it was played a while back so I decided to replace all the electrolytic capacitors but after this there was no sound at all.... * +

So I decided to find a company that could do the work for me. After an hour on google and a few telephone calls later I had found a company that does rework and circuit board repair. The guy even came to my work place picked the board and the new chip up and took back to his workshop to do the repairs. After a few days he brought back again. I checked the board over and the newly soldered DSP chip looked perfect. * +

I carefully reassembled the synthesiser then plugged in the audio jack cables to a mixer in the office sound system and then the power supply for the synth. At this point I was getting anxious to find out if it would work properly again..., * +
