DK2 Sudden Hardware failure

Anyone have the same Problem?

My DK2 was working fine until:

The DK2 all of a sudden has no Image, only orange LED. The camera is working fine. the Headset is being detected, and i see the mirror Image on my Computer Monitor and head-tracking works ok.

I tried direct mode and external mode, changed Drivers and SDK´s, changed the usb and hdmi cable, updated Firmware (again).

At the end i formatted the PC and installed all new, still not working, same outcome as before.

I took the HDMI plug that goes into the DK2 and plugged it in an external Monitor, here i can see an Image so the HDMI Signal is

reaching the DK2 ok.

Now the only conclusion is that my DK2 has a faulty Motherboard.

Question: if the (note3) Display is broken does that has any influence on the blue LED? is there somekind of checking Routine from the mainboard to determine the state of the Display ?

Question 2: where do i get a Mainboard for my DK2?

Anyway thanks to all.

Hoping to get somekind of answer to help me out.
