There is a black screen when turning on the system

There is a black screen during a few minutes when turning on the system. Then, the system turns on properly and can be used without any issue.

Remove any USB device from the central unit (USB stick, mouse, keyboard) and try again to turn the system on.
1. If it works, try to turn the system on with only the mouse plugged in. If there is always a black screen, did you heard the central unit ?
  1. If so, unplug the mouse and check if the Trinity starts. A change of mouse might be necessary.
  2. If it doesn't work, a change of central unit might be necessary.

Sometimes, if a USB stick is plugged on the system, the system tries to boot on this USB stick preventing the system to launch properly.

Otherwise, depending on the results of the tests, changing the mouse or changing the central unit might be needed.
