dropped nikon coolpix s2700 camera, still switches on but with a black picture in window and only takes black photos, can this problem be fixed
Unfortunately it can only be fixed by an expert, or at least someone who has a very good idea of the inner working and with access to replacement parts - which can be very difficult. So, I'm afraid it's a proper repair or replacement - same with many things these days. Nothing that can be done from the outside.
Always pop back and let us know the outcome - thanks
Those units were never designed to be repaired so obtaining parts is likely to be very difficult. And repairing a dropped item is particularly difficult. If possible to do at all the cost could easily exceed that of a new item.
