Hp monitor has no signal on both hdmi and displayport
Hi,
I have a Hp27b monitor that shows no signal on both the hdmi and displayport inputs. I have tried manually selecting hdmi or displayport on the monitor.
I tested this on two different laptops and both laptops are able to detect and identify the monitor on the laptop end. I tried updating the monitor driver and still the issue persists. The laptop is able to send the signal to the monitor, I believe the monitor itself is not receiving the output from the computer. I also tried different hdmi and displayport cables and same issue. I was able to get a signal on another monitor as well so that eliminates the laptop itself having issues.
Would this be hardware issue of the monitor? If so, would it be the logic board or the cables itself?
Thanks for reading.

This is what shows up right away, I don't recall if it's supposed to be show the hp logo when powered on.
Yes I can view the entire menu perfectly, I can browse to change contrast, viewing mode, input etc..

Are there any power on lights on monitor? Can you enable monitor menu (using buttons in monitor)? Or in a dark room; connect to laptop and power on everythin g-> use a torch light to shine and see if there is some picture visible(if yes, then the backlight is broken)

Yes, of course there is power on lights if I can select hdmi or displayport output on the monitor.... it literally says " input signal not found, check the video and cable source".

Dark room + torch check? next would be open it and see if there are any "leaked capacitors" - upload photos here.

Did the new mainboard fix the input issue? I have the same issue and pulled out the mainboard. Nothing obvious on the mainboard.
