Hi, I just turned on my projector today to find that I have a lot of verticle lines. This covers the menu screen and any films I try to watch. Can anybody help with this issue? It's still under warranty so the shop might send it for repair. Does anybody know how this has happened? I don't want to be accused of mistreating the projector as I take care of it very well. Thank you for your help.
