Acer Nitro 5 an515-51-720N , replaced display but the new one does not turn on

Hi,
I accidentally damaged my old display and i broke some pixels in the lower left area, creating a vertical band on the left side (2-3 cm thick) that's not turning on, the rest of the display it's working correctly.
I decided to replace it and i bought a new one, same exact model and specs just to be sure it's compatible. When i connect it, nothing comes on screen and it stays black and not powered. The notebook it's working normally and i can connect a second monitor correctly, but the new monitor it's still totally invisible to my notebook and inside Windows(i also tried the hotkey to turn the display on/off but it didnt work). I know the new display it's ok cause i could test it on another pc, so what could be my problem? I thought about a faulty cable, but my old monitor it's still working so i'm not sure what to think...

Hi, i tried what you told me but i couldnt make it work.
When i turn my notebook on with a second external monitor(via HDMI port) i can boot to Windows but i can only see the external one, my internal display it's not detected. When i turn the notebook on without an external monitor nothing shows up on screen, it's basically dead, but i can hear the system sounds confirming me that the notebook boots to Windows fine.

Well, are you sure you didn`t fried the new panel while testing it on other machine like you said? Test it again...
