  • uLCD-32-PTU white screen no matter what

    Hello,
    My uLCD-32-PTU suddenly went white when it was turned on,
    I Tried to flash older PmmCs on it,rebuild my project and tried even different projects
    My Project presentation is 2 days ahead and I really need to fix this,
    Thank you.

    If it went white after a PmmC update then the most likely cause is the wrong PmmC being loaded.

    If it went white after being turned on it would appear that the display has been damaged in some way.

    Inspect the flex connecting the display to the circuit board for damage.

    Also check that the flex is correctly seated in the socket and that the 'latch' is engaged.

    Perhaps try undoing the latch, ensuring the flex is correctly seated and then reengaging the latch.
