I've a Nikon D3. One day unexpectedly the rear LCD screen has stopped working. It shows only white lines, as in the attached pic. I've changed 4 screens:

  • the first: shows only few light green lines
  • the second: shows a little more lines, but this time are white
  • the third (maybe the only broken screen): works only the backlight
  • the fourth: works like the second (is the one of the pic)

If I use HDMI it seems to work fine.

Can anyone tell me what might be wrong?

    The problem could be upstream in some connector or electronics. – xenoid May 30 '19 at 21:26
  • Can you clarify what you mean by, "I've changed 4 screens"? – Phil Anderson May 31 '19 at 1:34
  • The first one is the original screen that broke during a shooting. After that I bought three other screen from China. – IlVileEzioGreggio May 31 '19 at 19:52

"Various copies of the same (active electronic) component working flawed in different manners each" tends to be a telltale sign of either:

  • some signal lines being disconnected, leaving inputs not connected to anything (due to tolerance or design revisions, a "floating" input can be interpreted differently by each copy)

  • marginal power supply to the component (each copy will have different exact power draw, making a failing power supply react differently)

  • marginal signal quality on some line (upstream component sending the signal is failing. Again, interpretation of marginal signal is copy-dependent).

This camera is not meant to be consumer-repairable. When you face a problem like this, send it into a Nikon repair center for repair.

You can't fix the screen, because it apparently isn't the screen that is broken, but rather something else that provides the signal to the screen.
