Lenovo c540 aio screen issue

This just started one day when I turned on my Lenovo.

 

I have lines in my c540  that begin when i first press the power button and gradually fade unitl i have green on the left side that fades to black.  Also should note i have no hdd connected. So the screen should be black with an error message.

 

I replaced motherboard with another one,  but could be a DOA gpu in the new one refurbished.

 

I created for demonstration purposes a vid on ytube.  Hope this is ok with Lenovo Forums.

Welcome to the Lenovo Community !

 

I assume that you don't have an HDMI out port in which to connect another monitor?  That would be a quick way to check the GPU.   Since the same problem has occurred with two motherboards you maybe looking at a defective screen rather than a motherboard GPU problem.  I also assume that you checked to see that the video cable is fully seated at the connectors and that when the cable is touched or wiggled the screen display doesn't change?

Nothing more than what I previously mentioned.  If the video output via the HDMI port is normal then I would suspect your problem is related to the screen or video cable to the screen.
