The call was for a blank screen. Arrived to find op panel dead. Black screen. Start button and power buttons are lit. Rebooted. Machine goes trough it's start up test. Seems to boot up, just a black screen. It is not the op panel as I first replaced that. Main Board? HDD?
Thanks for any ideas.

Every black panel problem I and my colleagues have had has been due to the mfp board failing. There is at the moment however a problem with ssd boards, so replacing them together seems to be the way to go.

If random lines of buttons don’t work however, that’s the ops panel....
