What is the problem when my camera's LCD viewer can't display images?

I have bought my IXUS 70 in Singapore last week. I started taking pictures using the memory card included and was successful. However, when I started taking pictures with another memory card, the LCD monitor turned blank- it only shows a black shadow (looks like it has been covered by a lens cover--in digital SLRs cases or the camera's appearing to be turned off). I can't take pictures as well since it only shows the black shadow. I have taken it to a service center here in the Philippines and they said that it is a factory defect, the sensor has a problem.

Any ideas on how to fix this? Or would you know if they will have the whole camera replaced since it is still covered by the 1 year warranty (the camera's still 1 week old). I'm worried that I would not get my money's worth. Please help. Thanks!

Act quickly and get it to a Canon factory warranty station. If it's a sensor defect, they'll most likely replace the camera, as the time and labor would be too much. Since the camera is new, turnaround time should be at a minimum, but the service center can best advise you about that.

Be sure you don't leave your memory card in the camera when you send it in.

I hope neither you nor the service center in the Philippines opened up the case of the camera, because if it shows signs of being tampered with, Canon may void the warranty.

just what george said and dont forget dont send them the battery either

it needs repaired
