Warm regards, Bob The Allens of Allentown, PA USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sony DSC-S40 ‘Quick Fix’ For the white/blank LCD screen issue As discovered by Bob Allen The Allens of Allentown, PA USA BobA5835@hintYahoo.com I recommend that you remove the batteries and make sure you replace them with fresh ones after you apply my ‘Quick Fix’. 1. Hold camera firmly in left hand. 2. Smartly rap front of camera with knuckles of right hand on the "Cyber-shot" logo. Replace the batteries and it will now work. For e-mail, drop the hint.
