NO POWER The problem we are having is no power. We have tried to different batteries and nothing. At one point if flickered and showed error 99. We have always used Canon lenses. The camera seems to get warm right above the battery compartment is and were the right thumb would normaly be placed. Can you help with some ideas? Thanks

Error 99 is common error on Canon cameras. Make sure the battery is freshly charged. Take the battery out, the compact flash card out, and the attached lens off of the camera. Leave the camera set for a while for the capacitors to bleed off. Around a half hour would be good. Next re-insert the battery and push the shutter button as if you were taking a picture. If you get an Error 99 then, you can't fix the trouble and Canon will have to do it. If you do not get an error 99, power the camera off, insert the compact flash card, power the camera back on and press the shutter button again. If you get an Error 99, the trouble is in the compact flash card or its connector. Try a different card. If you do not get an Error 99, power the camera off, a lens on it, power the camera back up, then press the shutter button once again. If you do not see an Error 99, the problem is no longer in the camera. If you do see an Error 99, power the camera off and remove the lens. The problem is probably in the contacts on the camera or the lens. Clean the contacts by holding the camera carefully with the lens opening down so it will not allow dirt to get inside the camera. Take a cotton swab dipped in alcohol and clean the gold metal contacts well, Dry the contacts with a tissue. Next hold the lens with the contacts down and repeat the process on the contacts on the lens. Be very cautious not to allow lint, dust, or alcohol to get into the camera body or into the lens. Some people use a pencil eraser to clean the contacts but you have be very careful not to let particles enter the camera or lens. This should clear your trouble, if the camera passed the first step of troubleshooting.

Hiyou have very common problem of canon dslr product. usually problem come from defective shutter unit. However, there is cause from lens also. Would you remove lens and push shutter button? if no error 99, then the problem come from lens---usually power diaphragm control fpc defective.If shows error 99, then you have body problem. At this point, still you have to check more. please set camera M mode and bulb shutter speed, you have to look front of camera if mirror goes up and show to you picture sensor. would you tell me more later. Thanks and best regard!

Is a motherboard internal error send to repair

Unplug every thing such as the CD/DVD trays, Hard Drive, take out any dial-up modems, network cards, video cards, etc. unplug even the mouse and keyboard. Try powering on agan. If the computer seems to work, then power back off and plug in one device then power on computer. Keep doing that until you find the bad device preventing the computer from turning on.

If that doesnt work then carefully remove the RAM completely then carefully replace the RAM. Now with on the Dynex power supply plugged in to the motherboard, try again. If still nothing, remove the RAM and try again. If it still does the same thing, then the motherboard is dead and needs replaced. If instead you get a series of beeps then the problem MAY be bad RAM. Try different RAM. If that doesnt help. The only thing left is taking out the CMOS battery, It is the coin shaped battery on the motherboard. Take it out and wait 20 seconds then put it back. I doubt it is the CMOS battery, but at this point it is worth a shot.

maybe is the hard disk malfunction

Err 99 usually means your lens contacts are dirty either on the lens itself or on the camera.

To isolate the cause of the issue, do the following: -
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert only a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, the camera may be faulty and requires a service. If it does not, then: -
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.

If the “ERR 99" message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99" with a different Canon lens attached, then the camera is faulty and should be serviced.

if you have a DSLR and your'e getting this "error 99" it may be associated with the particular lens youre using. try turning off the camera and removing the battery, the lens, and the memory card. let it sit for half an hour. reinsert the battery only and depress the shutter button as if you were to take a normal picture. if error 99 occurs again, then the camera needs servicing. if it error 99 doesn't occur at this point, turn the camera off and install the memory card. format the memory card while it's in the camera and press the shutter button as if youw ere to take a normal picture again. if you see error 99, then the problem probably lies with the memory card. if it doesn't occur, turn off the camera and install the lens. again, power on the camera and press the shutter as if you are taking a normal picture. if the error occurs, then it's with the lens. try to clean the lens including the connection points both on the camera and the lens. if the error code still occurs, try different lens to narrow it down to which particular lens is giving the issue. if it happends with all the lens, then the camera needs to be serviced.

Ifd the camera is only 3 months old - return it for replacement

Error 99 is a general fatal error.
which includes the problems above mentioned by Q4SteveB but also many others.

It can be caused by a dicky shutter, problems with the CF card interface.

If cleaning and trying a different lens has not worked. Not definitive but as a rule of thumb...
If it letting you take one picture then giving error 99.. and the picture is saved to the card (but may just be black) this is most likely the shutter needs replacing..

If it takes a picture and gives error 99 but there is no picture on the card or the picture is 0KB its a CF interface problem.

If you get an error 99 when you plug in the USB its a USB interface error, you can try a different cable but unfortunately in most cases if another lens or cable wont work it needs repair
