Display not working after Motherboard Installation

I purchased a replacement motherboard (v 1.4) and have installed this according to the procedure shown in this guide. The motherboard powers on, the fan spins as it should but there is no display showing. I have tried reinstalling the RAM and re-booting but no luck . The display still does not show.

Does you have any suggestions? I am at a loss at the moment.

Its turned out to be a faulty motherboard. I bought a replacement from Alliexpress and it has worked perfectly. Got into the Bios 1st time round without an issue. We think that the graphics card on the old motherboard was the problem.

Thanks for all the help.

If you haven’t done so already, look through the ifixit guide again and recheck all your ribbon cable connections.

Does your model have the HDMI port? If so try connecting to another monitor or TV to see if you get anything.

I have checked all the ribbon connection cables. I have even tried connecting to another monitor. It is probably something simple but at the moment I can’t work it out.

So you see nothing on the screen, not even able to get into BIOS?
