http://forums.cnet.com/7723-7593_102-56917/canon-e18-error/ seems to show folk have avoided the repair counter.
I have a very old, but well taken care of, Cannon SureShot A520 and I have an E18 on the LCD. Will someone tell me what E18 is and how I can fix it? I use it for preview setup and then use my DSLR to take the final picture. It really has served me well in that capacity. Thanks
That error can be caused by a battery problem.
If you are using rechargeable batteries, they may have reached their end of life.
Use new alkaline batteries as a test.
The lens housing may be slightly bent.
With the camera turned off,
lay the camera on its back and look closely at the concentric rings around the lens.
See if they are equally spaced.
Press on any ring that has unequal spacing and see if that helps to align the rings.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
