HP ZR2740w goes black after starting

HP Recommended
HP ZR2740w
Microsoft Windows 10 (64-bit)



My HP ZR2740w goes black just after starting up : I can see the desktop for less than one second, then the screen goes black (the LED remains off, it is not blue or orange).

The screen is detected in Windows display settings (I have two ZR2740w screens so I can see what is happening from the other one).


I cross-tested everything :

- I switched the cables with the other screen, using DisplayPort and DVI-Dual, the issue persists

- I switched the power cable with the other screen, same issue


Could it be an issue with the backlight of the screen?

If this is the case, do these part still exist?



Thanks a lot.
