All White Screen and a strange Buzzing Sound

[Flavor]

If you have the ability to connect to HDMI, that would probably help a lot. Then you can see if everything else is working correctly. That could indicate that it’s something to do with LCD connection or if it’s the whole operating system having a problem.

Since you do get the greenlight to come on, that’s a pretty good indication that the operating system is booting up in the background and you just can’t see it. How long did you wait with a white screen?

I’m just on my phone at the moment, and I can’t get the video to play here.

Based on your symptoms, my number one reaction is that the LCD ribbon cable isn’t fully connected. I know you said you watched a video about that and connected it up, but if you could show any photos or videos of how you have it connected to that could help. I would say that is by far the number one issue when people have a white screen.

Did you ever get the system to boot up properly with video on the LCD? If you changeD the video setting, and some thing went wrong with that, that could also cause the white screen to happen. The easy way to tell if that’s the problem is to start fresh with a new SD card image.
