Hi there Alfred:
Here is my very own "Quick Fix" everyone has been referring to here on Pechorin's for the dysfunctional Sony DSC-S40 digital camera with the white/blank screen problem:
1. Hold camera firmly in left hand
2. Smartly rap front of camera with knuckles of right hand on the "Cyber-shot" logo.
This thread was started by me on July 25, 2006 if you'd like to see the entire thread.
I'll e-mail the pics to you, but be advised I disavow any responsibility for them. I didn't need to crack open the camera and if you use my "Quick Fix" you won't need to either. The "Quick Fix" seems to be permanent as well.
Please post back and let us know how you fare.
Regards,
Bob
