Repair Roland JP-8000 Synthesizer Tutorial (A2019111701) Reparatur
Another Roland JP-8000 Synthesizer on my bench today that has a weak output. If you want me to fix this for you, but you don't want to send in your whole synthesizer, I created this tutorial for you. It's maybe also useful for other techs who wants to repair it themselves.
1. Unplug your synthesizer from mains !!! Remove all other cables like audio and/or MIDI.
2. Flip over the JP-8000, so you have access to the black buttom panel. Be careful to lay something under the bender to support it and not to damage or break it.
3. The loosen all the black screws. I recommend an electric screwdriver here ;)

4. Next I suggest you loosen all cables. Starting from left to right with the big black on on the left. STOP! You cannot just "pull it out". First you have to unlatch the cable from the plug. Grab it with your fingernails left and right or use a screwdriver and carefully lift the white frame up like so...
8. Once you have unscrewed the shielding you can remove it. You now should see the "motherboard".
STOP! Don´t touch it.
You might be charged with a static voltage that can damage the components. If you just want to change the battery, you can do that now. Don´t forget to back up your memory first :-)

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.
