JMP-1 Faulty

[jimi123]

Can somebody help me with this, I have a JMP-1, that I bought it brand new a couple of years ago, never gigged with, and don't used that much, I use other stuff instead. Yesterday I turned it on and a message in the display show ?Patch 6?, then nothing happens and I couldn't turn it on anymore since then. If you have any idea please help

Thank you

Is it still under warranty?

No

Start with the power supply, there will be multiple voltages, make sure all are present, up to proper voltage and clean of excess ripple.
