Roland JP-8000

“The unit powers up and all the buttons and lights turn on but there is NO sound output from the headphone or the L/R main outputs. We sent it to a shop for diagnostic and upon visual inspection they noticed that capacitor C219 and the traces that connect it to the board where completely missing. These keyboards suffer from a common problem of bad capacitors. It’s likely an inexperienced person tried to make an unsuccessful repair and damaged the traces to the C219 capacitor. All the external knobs and switches are intact and the screen display is also visible when powered up. There was no other visible damage to any of the other internal components. The shop used a sound generator and determined that sound can process through the jack board so it’s likely the main culprit is in the Main Board A. This would be a good project for someone skilled in electrical repair or as a parts donor.”
