My EOS 70D has a problem in the LCD display. It shows images (and menus), but everything in green and pink. Pictures and videos are taken normally, it is just the display that has the problem. I already replaced the following parts (shopped at AliExpress) with no results: LCD screen, LCD flex cable with hinge, display board (little board behind the screen). Next one that I can think of is the main board, but that one is quite expensive, so I wonder if anyone has had that problem before and could tell if something else solved the problem, or if anyone can suggest anything else to look at. Thanks.
