Minolta Dimage A1 viewer is BLACK

If the CCD is broken then you'll get a distorted and discoloured image on the main LCD screen and in the viewfinder, but both will play back images recorded prior to the fault perfectly.

What you seem to have is a very common fault which eventually seems to affect all A1's and A2's, and which may explain why KM fitted a fixed viewfinder to the A200. basically, there's a flexible circuit board (pcb) which snakes it's way throughout the camera. Where it passes up into the viewfinder it's simply not protected enough from a couple of hard plastic edges which it passes over.

Eventually, one or more conductive tracks fail and the ones which power the backlight for the miniature LCD screen in the viewfinder are the first to go.

Replacing the flexi pcb is simply not a practical option as the camera has to be dismantled virtually to component level and new pcbs's are made of purest unobtanium. Even if you could find one, KM never beefed it up to solve the problem.

The best you can do is to remove the two screws on the underside of the viewfinder and remove the lower cover they hold in place. Turn on the camera and make sure the viewing switch is set to the viewfinder. At the lower right corner is a little piece of blue (sometimes yellow) tape and this is KM's pathetic attempt to prevent the problem occurring. If you gently lift the tape and flex the pcb a bit, then you may find that there is a position where the backlight illuminates. You'll probably need plenty of goes to get it right, but if you screw the cover back on and lower the viewfinder back into it's resting position it's often possible to keep the finder illuminated. You'll then need some means of locking the finder so that it cannot easily be raised again. This repair rarely lasts for long though as even minor knocks can cause it to fail and the even worse news is that the damage gradually spreads to other tracks killing the finder completely.

you will have to replace the CCD chip alone. it is worth fixing. you can go ahead. but do it with some authorized service center.
