Since you got this far...why not just go ahead and UNLOCK your cluster so that you can access the other 21 TESTs if need be.
To unlock...add up the last 5 digits of your VIN...what ever the sum of those last 5 digts are...that is your X5 specific "magic number" to unlock the cluster.
When you try to use any OBC TEST that is locked (3-21) on an UNLOCKED cluster...when you see the message that the cluster is locked...you're already at TEST 19. Begin pressing the LEFT cluster button until you reach the sum of those last 5 digits of your VIN...then press the RIGHT button to set it.
Your cluster will remain UNLOCKED until power is lost to the cluster (like removing battery cable).
And if none of the pixels illuminated when you did TEST 2...and if the back lighting in the area was already dim before the pixels went out...then not only do you need to replace the incandescent bulbs mentioned above...you've probably got pixel issues and will need to get a new LCD core...or ribbon repair.
The e38/e39/e53 pixel issue is very common. In fact, I just got my e38's cluster repaired on a group buy on the e39 forum. It was sent in to Concrete Donkey (bimmerforum member) for repair. The original cluster was replaced back in 2003 in the BMW goodwill cluster program. And the cluster was great until about 2012/2013 when pixels started dropping out in odometer and 20 digit alpha/numeric display. In this last fix the LCD core was replaced and a new ribbon installed (with lifetime warranty).
