I am a chromebook repair tech that teaches students , the models that we have been focusing on are the R752, and the R753T. We seem to have a large uptick in units, that when the daughterboard is connected the units loses the image to the display. Even after several daughterboards, the same issue occurs.

Yesterday I was able to confirm the issue only occured after updating. If an solution is not found dozens of units will be deprovisioned.

[Edited the thread to add model name to the title]

    Are you talking about the USB daughter card, the LED daughter card or the touch pad? None of those seem to be anywhere the connection to the display routes. What happens when you try an external display with the card connected?
