The camera will not allow you to take pictures because viewfinder does not show anything but blue screen. I can see the pictures from Mini CD on viewfinder but no actual images from camera lens. Everything else works. Battery is good and I have replaced the Mini Cd several times and nothing corrects issue. You should ask a Sony camera service centre...but there might not be much you can do to get the problem fixed. You might have to buy a new camera.
That camera is almost 4 years old! (it would be classed as a relic, in digital camera terms).
It might be a good excuse for an upgrade...more megapixels, faster camera performance, better 'movies', more photos via memory card etc. braek it or sell it stupid |
