I'm having a huge probelm with a sumvision SV-1001. Basically, when I got it, I couldn't hear any dialogue on DVD's, only music (I have since discovered the solution to this problem!) and whilst trying to fix this in the menus, I have somehow managed to turn the screen black. I have no way of explaining this any better and several people have tried to fix it without success. I have tried everything obvious like turning it off, switching cables etc but no luck. I jsut don't get any image or menu whatsoever. Does anyone know how to restore factory setting or reset the DVD palyer preferably without being able to see anything?
I know this is a bizarre query but any help would be greatly appreciated
