Hi Dave, sorry to be a pain again, have been using this unit on and off for the last couple of months. I went to use today and the screen just won't come on when I boot to windows. When not connected to the HDMI I get the flashing colours but when a video source is connected the screen stays blank. I initially thought the back light was a bit dodgy previously and sent it back, it did seem to work great though since then. The video is present but the back light isn't activating. If I cast a light source onto the screen I see the Windows 10 home screen and can operate the touchscreen etc.

PS I have tried various Windows machines, they all exhibit the same problem, flashing screen colours then video source is detected and the back light disappears.

Hope you can help?

All the best
J

Really sorry to hear you're still having trouble!

What power supply are you using?
Are you able to try a different PSU? It needs to be 5V @ 2.5A but if you can find a 3A PSU even better!
If you have an EU to UK power adaptor and still have the original EU PSU that comes with the screen, could you try that as well please.

If you can rule out a PSU issue then could you try the following (make sure nothing is plugged into the screen for this)

Remove the rear acrylic plate by undoing the black nylon nuts from around the edge (there should be 7 of them)
Once the acrylic has been removed please check the following

On/Off switch - Just check that the switch toggles properly, isn't getting stuck and that there's no damage around it.

40 Pin Ribbon cable - Please remove this cable and re-attach it to make sure it's connected properly. The gold connector edge just pulls out/pushes in. The side attached to the blue controller board, there's a little black thing that needs pulling out before removing the ribbon.

After that re-assemble and see if anything is better.

If no better then I will have a replacement arranged for you as there is obviously an intermittent issue with the screen.

Thanks for the quick response Dave.

I have tried both adapters that came with it, the Rasp Pi branded one and the original one.

I will do those other checks when I get home and let you know.


Best regards
