HP Chromebook 11a G8 Screen

[DavenH123]

I've gotten 5 or so devices over the past week that have what I call a dead screen. When the Chromebook powers up, you can see the faint outline of the login screen, or it shows a faint glimmer of a gray screen, but nothing is really visible. Swapping screens has worked with other models, but not in these cases. Has anyone else had this issue, and is it a matter of swapping out the LCD cable or something else? 

Thanks

I've now gotten two of the same models that have WiFi issues. They show a strong internet signal but won't connect to WiFi to even allow signing in. Powerwashing doesn't fix this issue. I hope this isn't the sign of things to come.
