I bought a used Blackmagic pocket cinema camera last week. It was ok then I noticed a few green spots on LCD 3 days ago(bottom part), and today I noticed it grew bigger and also I noticed a new lines emerged top right.

What's this issue called? Is it a problem with LCD or sensor? Why it grows?

I ve been using Canon, Pentax, Sony DSLR cameras over ten years, and haven't seen anything like that before.enter image description here

  • \$\begingroup\$ @scottbb not really so I have been thinking it was an LCD thing. Though I can't understand why it grew. \$\endgroup\$
