I'm having the same problem here. It's July 6, 2014 and Dell and Microsoft still have not fixed these issues. I hate to return the device, but I don't have much faith in a forthcoming solution.

I have a Dell Venue 8 Pro tablet. The screen of the 8 pro often doesnt turn on after pressing the power button (to get it out of sleep) or after pressing the windows button. Only the backlight turns on.
Sometimes, after pressing the power button numerous times the screen turns on. (numerous = >50times)
Doenst matter if the battery is 100% or 10%.
The screen also doesnt turn on booting it up (after powering down).
Also when i press the power button + volume down immediately after (to enter the bios), it shows a black screen with backlight on.
I have made a video of it (the first 20 seconds the 8 pro is booting up, see the white led flashing):

I have installed teamviewer on the 8 pro and i have logged on with my laptop 3 times while having a black screen on the 8 pro.
The strange thing is, when viewing the 8 pro's screen with teamviewer, i can see the touch screen of the 8 pro is still functioning. See this video i made:

Each time i watched the system event log, and saw warnings like:
'a pointer device did not report a valid unit of angular measurement'
'a pointer device reported a bad angular physical range'
'a pointer device reported a bad angular logical range'
2 pics of the system event log:

I have installed all the laters Dell drivers and flashed the Bios (also from Dell). Also i installed the latest windows 8.1 updates.
I have rolled back the installed Intel graphic drivers to standard microsoft drivers, but also with the standard drivers the screen occasionally wont turn on.
This device is rather new. What can i do to fix this?

I have had no issues since upgrading to the latest BIOS/Wifi firmare and applying the patches in the correct order (should be automatic by now)

I'm happy to hear that you are not experiencing these issues. However, my device is new and I assume that it already has the latest BIOS/firmware (BIOS is A04). I have performed all updates as prompted by the device. The issues persist.
