Caution

In the last few weeks I repaired a few more Roland JP-8000 synthesizer. They all had a weak output problem. Once again caused by bad electrolytic capacitors.

Caution

In this story, my customer brought in two Roland JP8000. One is used on stage, the other is a back up.

Caution

There is one electrolytic capacitor in the mute circuit of the Roland JP-8000 that is faulty. In the picture you will notice a dull looking solder joint. These 22uF caps leak, or have high ESR. Sometimes they also have low capacitance. Replace it and the output will work fine again.

Caution

There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.
