The lcd screen remains black even when i turn on my canon powershot A620.

Press the DICP button 2 - 3 time and see the LCD turning on or not. Let me know.

From my experience, there is a setting on your camera (to preserve battery) that makes the screen black. There is probably nothing wrong with your camera, you just need to find the DISPLAY button and push it until you see the image on your screen.

If you do not have a manual for your camera, you can download one here:

Hope this helps!

You will have to replace the LCD screen, since it is broken. You can get an "as is" same model camera on Ebay with a good lcd, or sometimes they have the lcd's on Ebay, if you search for them by make, model, and description (lcd screen).
There are YouTube videos that show the general process for replacing one. Here are a lot of articles that will explain how:

Good luck, hope this helps, and thanks for using FixYa.

First try pressing the DISP or DISPLAY button on the back of your camera. If that didn't fix it... A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

My A620 JUST started doing the same exact thing last night. LCD works, lens works... but something possibly wrong w/the shutter so it won't open.. everything black.

If the camera shows the menu, it can be two faults - dead CCD or stuck shutter. You should contact local Canon service center.

Think that you accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

If the screen goes black, you can still take pictures. There is no way to fix the black screen, it just blew out.
