Maybe a sensor is bent, telling the camera it still has the external flash attached.

How do I use this flash as a slave?


You need to set the flash to slave and the same channel as the master. If the flash doesn't have this function it may be able to be fired optically. Set the master flash to low power and set the off camera flash to optical.

How do I diable my in-camera flash and still be able to use my external flash unit as a slave?


How to use the internal flash as a commander is in the manual from page 189. The manual is online.
There follow 10 pages about all different settings for the remote flash mode. I could not find how to use the internal flash as a commander and switch of the commander itself. On my Nikon, I can use the light as a commander and when the picture is made the build in flash does not fire.
You always see the internal flash fire, before the picture is made, because it has not only to tell each group what setting it should use, but it also has to trigger the external flash groups. If you want to use the flash as a commander while photographing persons, you can use a Infra Red filter (little one) in from of the internal flash, so the subjects won't close their eyes. Look for the Nikon SG-3IR filter. I think Canon must have filters like this.

I have a 94 dodge stealth non turbo sohc that has starting issues. I've replaced the fuel pump, fuel filter, plugs, wires, distributor cap and bug, and the coil. It will turn over but will not fire up....


All dodges have a bilt in code check, on my 94 caravan, i have to rev up the idle to approx 2300,for 10 seconds, turn off all accessories, put foot on brake in regular idle, put shift lever in all gears, go back to park, turn key on and off 3 times the third time leave in start position and watch the check engine light, it will flash in series, first will be 1 flash followed by two quick flashes, this tells you your computer is working(not a problem code) then watch for other flashes and write them down, the last code should be a 55, meaning 5 quick flashes followed by 5 quick flashes of check engine light, at least you can diagnose some problems this way, best to purchase manual from autozone, there is a section on this process, or take to your local autozone and have it done free

I have conon 60D it is brand new that i have often used but pop up flash does not work after using external flash also I do not have flash indicator light on. inside light meter in the build in flash...


The problem is under the hotshoe plate. There are extremely small hols where the sensor for the internal flash are positioned. These sensors tell the camera when an external flash or some other accessory is mounted on the camera and not to open the internal flash. What happens is because the alignment of these hols is so precise and critical any amount of movement or minute partial of dirt can upset or stick these sensors.

What has happened is that when you removed your external flash the sensors did not reset because of dirt or misalignment so show the setting as if the external flash is still mounted and that's why the internal flash won't pop up.

How to fix it, well for a repair person it may be a simple fix by slightly loosening the hotshoe and cleaning the dirt from under it and realignment. It'll work again until it gets dirt in there again or misaligned. This is one area that Canon shouldn't have been so precise.
I'm not suggesting you do this but when I had the same thing happen to one of my field cameras I took a hard plastic coffee cup and lightly started tapping on the edges of the hot shoe. After a few light taps around the shoe I the internal flash popped up. Once I finished my shoot I sent the camera to Canon to have the problem repaired properly. Repair and shipping to a Canon facility cost me $65.00 Canadian.

I bought my new canon eos 60D..i put on external flsah to use..then after i take off the external flash, my camera's built in flash cannot pop up to take flash even i had press the flash button. How?


Hi, What external flash did you use on your Canon 60D? The internal flash will not automatically pop up if in the "Creative Zone" it will pop up with the button in the creative zones (M, AV, TV and P) it will not pop up with the button if you are in the the full auto mode (that's the little green box mode) but, should pop up automatically if required. The flash should pop up automatically in the basic zone for Portrait, close up and night photography, the button won't activate (pop up) the flash. Also the internal flash will not pop up if there is an accessory in the hot shoe. Again what external flash was it you used and did it flash?

Flash fires irregularly... good exposures, then suddenly 3 way under exposed/black then a good exposure, the a completely burnt out over-exposed shot! Completely irregular.


If you are referring to the internal flash I would say you are firing the camera faster then the flash can cycle. There is a green lightning bolt that will come on in the viewfinder when the flash has charged. If you fire the first one it may be a charged flash then again you may have popped the flash composed and tripped the shutter before the flash has had a chance to fully charge. You fire again depleting the charge some more and before it has a chance to recover you fire it again so the flash never has a chance to fully charge. You need to wait till the flash ready light come on in the viewfinder.

I have a pavillion pc the fans work but it will not fire up


Fans meaning CPU and Power Supply and Chassis? Try taking out your Ram and see if you get a beep code. If you do that's good, put it back and take out your video card, again for beep code. If you have internal video, during boot up try a combination of keys which used to get you to BIOS? Can't? Try putting in an external video card. Do you get a screen? If not, it could be your processor, although we really haven't ruled out your Video yet. Does your keyboard flash when you turn on? Try holding down a key for about 30 sec. while booting and wait for a beep. You should go into BIOS.

Internal flash not working because of non compatible flash installed


Solution:
Look at the external flash socket.
With the camera in "normal position", i.e., poiting away from you, you shoul see a very small (I realy mean very small) piece of plastic under the rigth inside of the flash shoe... it is the "external flash sensor". It probably is stuck. Work with the point of a knife to try and release it.
In more detail, if you look carefully at the external flash shoe, the are two metal pieces that will help create some pressure. So the flash holder (shoe) is made of two parts: a very rigid one and the metal blades that create the pressure. Look under the blade located nearest to the shuter button.
If you can locate the plastic piece (black in my camera, but can be white) try to have unstuck.
Worked with my camera.

My powershot G9 built in flash is not working


There is a switch on the hot shoe to detect the external flash. When you use an external flash, the switch will be pressed down, then the unit will bypass the internal flash and won’t let it fire. If the little switch gets stuck somehow, you won’t get your internal flash on.
Check this switch on the hot shoe (either on the left side or the right side), blow some compressed air then plug/unplug an external flash several times. Hopefully you can get it back

PROBLEM: F828 & external flash


I think this is due to the TLL preflash of the 828 internal flash. Each time it actually fires 2 flashes. First one for metering and second one for actual exposure. First "fake" flash probably trigers your external flash which is too early. Slution... hmm i think there are afordable slave adapters out there which detect the TTL preflash, ignore it and fire the external flash on the right timing along with the main flash. cost.. about few tens $ i think. they can detect also infrared light so you can mount IR filter on your internal flash to prevent interfering with the exposure...
