I contacted Canon Tech Support and received the following info. There are two conditions under which a blinking "H" will appear in the LCD panel: (1) when the film has been loaded incorrectly or (2) when the camera's self-test process detects an internal malfunction. If a blinking "H" indication appears, perform the following operations in attempt to resolve the situation: 1. Rewind and remove the film using the rewind button, then remove the battery to clear the memory. 2. Clean the contacts at the base of the battery compartment with a clean pencil eraser to ensure proper contact between the camera and battery. 3. Replace the battery, power the camera back up and operate it as if it had film loaded, pressing the shutter release. If the "H" display stops blinking, the problem is corrected and you can continue using the camera normally. If the blinking does not stop, or if it subsequently returns, the camera should be examined by an authorized Canon service facility. For factory service, please forward your camera to the Factory Service Center shown below. When shipping your camera, please be sure to remove the film (if possible) and batteries.

Try this as a last resort. This blog post outlines repair procedures for a stuck lens covers. An A400 is used as an example. But for the A620, you might want to extend your zoom all the way out before removing the camera's batteries. Also you'll be applying the ring loosening rubbing alcohol along the barrel's perimeter instead of the front as shown in the procedures.:
Good luck, and remember do this only as a very last resort. Oh, and please post how it went should you decide to try the repair.

There is a very very easy way to fix this problem..
This can happen if...
1.) If the battery dies when the camera lens is open (and you close it manually, or sometimes, even if you dont.)
2.) If you used a AC adapter with too much voltage or not enough. (this can happen even if you used the correct voltage, refrain from using AC adapters at all)
... all together its ethier a voltage or camera lens problem...
1.)NEVER PUSH THE LENS IN AFTER CAMERA DIES, BUY A NEW BATTERY IMMEDIATLY AND TURN IT BACK ON, CLOSING THE LENS!
2.)NEVER USE AN AC ADAPTER, USE A RECHARGEABLE BATTERY OR A REGULAR BATTERY!
..to fix this...
Do as i say..
1.) Remove battery
2.) Remove front plate (screw driver may be needed)
3.) Check all gears, make sure they are correctly fitted in place)
4.) Move the gear manually to make the lens come out.
5.) keep it out, put the front plate back together.
6.) reinsert the battery, turn it on.
1.) Remove the battery.
2.) Wait about 6-8 hours.
3.) Reinsert the battery.
1.) Remove the battery.
2.) Try hooking it up through AC adapter, put correct voltage.
3.) Try turning it on.
4.) Remove AC adapter, reinsert battery.
5.) Turn it on.
Hopefully all this information helped,
I just had the same issue when one of my children drop the camera. I'm not wanting to break anyone's camera but I was able to open the lens cover and pull the lens out and then turning it on it retracted and worked just like it should.

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...
Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:
