Flashing Inverted White/Black Flash Sign - NO FLASH
Our Canon PowerShot A640 flashes a logo on the LCD with a black thunderbolt overtop a white square background. It flashes repeatedly once zoomed in on photo subject and attempting to take a photo with flash. We have tried sevaral settings and even new sets of batteries - no luck.
I hope someone else can tell us something to try.

make sure the dial at the top of the camera is set to AUTO or the green camera icon. When you are in position to take a picture, press the left button on the circle pad on the back of the camera; it should look like a SQUIGGLY ARROW this is the sign for flash. that button should turn it on, off, at automatic based on the current lighting.
Hope this helps!
Sounds like the flash capacitor is not charging. Usually the cause is a blown fuse. This is a hardware problem, not software, and the only solution is to take it apart and replace the fuse (it's a SMD fuse and it has to be soldered). Sometimes the problem is with the flash board. I'm afraid you will have to give it to a camera technician. I could help you with the repair, but I'm in Germany.
Hi there, you could buy the lcd panel from canon for about $50.00 but it is a little tricky to replace. If you do open the unit, discharge the flash capacitor first other wise you may be in for the shock of your life if you accidently touch it!
I sent my camera into Canon for repair. They said the flash was malfunctioning, and there was something wrong with the flash exposure control. The repair cost about $87. It took approximately 10 days from the time I sent the camera in until the time I got it back.
It's not your LCD, otherwise you would have heard the sound of buttons being pushed. If your units first screen is white and there is no logo screen or any legible images, then it's your NAND flash on your main board. The first image produced upon boot is the blue magellan screen. This is produced from the NAND flash and will show it no matter if a hard drive is present or not. After the Magellan screen it pulls images from the hard drive. So, it is the mainboard and the only way to fix it is to send it to Magellan repair and they will have to put in a new mainboard then reprogram your serial number, etc.
