screen remains black ThinkCentre Edge 91z

I have the ThinkCentre Edge 91z for quite a while now but the monitor isn't displaying anything anymore.

It all started about 2 weeks ago, the monitor would randomly turn black and display weird pixels over the screen but the screen would still go back to normal after a short time (about 10 seconds).

After that i decided to restard the pc but the monitor wasn't displaying anything, It would only show me the "power saving mode" message and goes to sleeping mode after that.

Sometimes i manage to get out of sleeping mode, the monitor starts displaying the same weird pixels for about 5 seconds and goes back to sleeping mode

I even tried to connect my computer to a laptop with a HDMI cable but it won't display anything

These are the 2 things the monitor displays when the computer gets out of sleeping modeP_20190620_205001.jpgP_20190620_210113.jpg

Re: screen remains black ThinkCentre Edge 91z

Hey there, snake9738! 


Welcome to the Lenovo forum discussion! 


Based on the images that you have sent, this is clear hardware malfunction with the Lenovo ThinkCentre Edge 91z. We highly recommend bringing the all-in-one to a service provider (filter by country) and inquire for a complete diagnosis/repair service. We hope everything will turn out smoothly.
