I don't often work on Fresenius machines anymore so I have a question that is probably easy for those who do. I have a T machine that boots all the way up but has a blank display. Even with the display blank if you hunt for the RINSE button you can still run it through that cycle, so I know the display is taking commands.
Is that a screen issue or is there some sort of graphics card or cable that could cause this? Thanks to all.

Sounds like the back light cable might be unplugged most likely from the screen side. Was the card cage worked in recently?

Like stuff stated, most likely a loose cable on screen side.

Check p-4 on the function board and make sure the wires from the 90 degree connector are up, not down. I'd also look at P41 for the same thing.

I believe it is the J8 or J7 cable at the back of display connection. Had that happen to me a couple of times.
