Prime 4, problems after long period of downtime

Engine DJ Hardware Standalone Controllers
1

Hello there, First time after almost 3 years of using I‘m writing an issue report. I have the Denon Prime 4 controller, and it worked always perfectly, but it had a long period of downtime (like 6 months), It was kept in a case in an upright position. I turned it on yesterday and it doesn’t work.

  1. It took a very long time to turn on, it looked like there were no any lights on the controller. Only screens on decks were turned on.
  2. I had to restart the controller after few minutes.
  3. When it finally worked and was connected, I encountered the following issues:
  4. No sound output to both the master and headphones;
  5. Hot cues do not respond to clicks;
  6. Pitch also does not respond.

After that I made an update from 4.2 to the last version, but it also didn’t help.

Has someone these problems and can give me an advice?

No-no, absolutely not possible.

Then yeah, it’s deff not moisture. In any case, nothing you can do other that take it to service center.
