Bought a new lens from ebay, replaced it and it worked for two days. But now, when I hit the ON-button, lens go out, the titlescreen pops up but then all is black. And when I try to turn it off, the lens won´t go back in. There is no message of lens error. I can push the playbutton to get the lens to go back in. And I can also see old pictures so nothing wrong with the LCD. Could the new lens be damaged? Also tried to reset the flexcables several times but the problem remains. Any ideas out there?
