So i have this monitor that turns on normally at first but then turns off after like 5 minutes.

But then everytime i try turning it back on it goes on for like 5 seconds and then shuts off

The power led stays on but the screen is completely off

For the record, there is absolutely no error messages whatsoever

The monitor is a BenQ senseye+photo
