I dropped my camera and hit the lens and now auto focus does not work


You'll probably need a professional repair. Compare the cost of repair with the cost of replacement. On that lens it could be about the same.

HOW DO I SET MY CAMERA TO AUTO FOCUS


The D90 has three different autofocus modes. In the AF-S mode it will not shoot until it has focused. In the AF-C mode it will shoot when you press the shutter release button even if has not focused. In the AF-A mode the camera switches between the AF-S and AF-C modes so either can apply.Also, bear in mind that the camera doesn't really know what you're taking a picture of. It may focus on something other than your subject. If you're in the single-area AF mode then you control which of the eleven focus points the camera uses. In any of the dynamic-area AF modes the camera decides.For full details on how the various modes work, please consult your manual. You might also check out the Nikon D90 video tutorial.

Prints small wavy cyan lines about one inch apart horizontally about 6" down the page. They are on the belt as well. Will just replacing the Cyan toner fix it? How can I safely clean off the belt...


Try to remove supplies and clean the printheads. If this doesn't resolve the issue, you may need to replace the color photodevelopers.

I suggest you contact Lexmark Technical Support for further assistance.

It doesn't allow me to take a shot. On a lense itself, there are two settings A and M. When it it is on M it takes a blurry shot, but on A setting doesn't allow. Please, help me.


M means Manual Focus. If you set the lens to this then you need to turn the lens manually to get it into focus.
A means Auto Focus and when the lens is det to this it should focus automatically but you need to set the mode button OFF Manual. It should work on any other setting.

Our Canon EOS Rebel XSi no longer works on auto focus. The flash works but the camera just makes clicking noises and the screen says "busy". Any suggestions? The camera works fine in manual...


Optical focus relies on a gear driven motorized system to focus the lens. It sounds like the drive is either frozen by a foreign object (it doesn't take much) has gotten into the system, or a tooth has worn/broken on the gearing.

Try taking the lens off and blowing the camera out with some canned air. If that doesn't do it, it's a trip to the repair center.

Hi Ref: Digital Camera - Pentax K200 model It keeps auto focusing when in manual mode. Regards Chris


Putting the camera in manual mode still doesn't change the focus routine. If you want manual focus, there is a switch near the lens on the left allowing AF (auto focus) and MF(manual focus).

Toshiba 57hx81 tv has a bow at bottom of screen and blue in color tried using toush focus & got error then tried to focus manually & couldn't get the bottom lines to focus all the way down


noted in the owners manual, if auto focus returns message "error" , it suggests to use manual convergence setting..failing that, is it resonable to suspect that the STK-392-110 (convergence (2)chips)are beginning to fail, bendt horizonital lines is the effect. you can check all the resistors and pico fuses (power board)near the chips for shorts, chances are they are ok. seeing that there is somewhat of a picture (kinda like 3-d). i would repaired it!.. while your there do the hyperboard repair as well by replacing the 10 caps with 16v@10uf. (causing a wavy vertical distortion effect).
