I have a Ricoh R8
Hi, well when you say "Every photo I take flashes white" (sic) however then you say (sic)" (In another camera) the same photos review without problems" Well in this case I feel that the camera itself, the actual image taking and storage are all Ok, what is in fact wrong with your camera is the Display, and or the Display driver and electronics.
So I do not think any settings etc, will indeed have any effect. Rather there is a fault with either the screen itself, the power supply to the screen, or the screen driver electronics.
The only way to remedy this situation is to get this camera looked at by a professional so they can isolate the exact cause and repair it. If you are worried about costings, then the best thing to do, is to ask for a "Quote" for the prospective repairs, this way at the least, one can then when in possession of all the details can then make up pnes mind as to repair or replace?
I say this as many of my customers these days prefer to put any monies, that may have had to be spent on repair, towards a new unit with a warrenty
