After years of flawless operation my G12's LCD screen suddenly will not display but remains black EXCEPT in Video mode, C2 mode, & when looking at various photos on the memory card. And..if I take a pic with the black screen in Auto mode I will hear the focus beeps (but no green squares display) and the G12 takes a normal pic which then displays fine on the screen. It's just when I'm ready to take another photo, finger on or off the shutter-release button, that the screen goes black again after a few seconds. Switching to Video mode the screen comes on again & remains on. Any ideas wahts wrong? I didn't drop camera, didn't get wet, the battery is fine, and i tried a different memory card. thanks!
