I just RMAed my Sony DSC-W30
It had a few "issues" when the flash was used, such as pictures turning out either completely green or completely blue. It would become permanent if the white balance setting was set to "Flash" resulting in a trippy green tinged LCD.
It had been doing it ever since it was bought, which was 3 months ago. Generally I wasn't too impressed with the way it handled white balance (pictures usually had too much contrast) so that could be related to the fault, or just me being pedantic :icon_cool
I just hope the online store I bought it from doesn't suspect I chucked it around (which I certainly did not). I'll update when they get back to me
