My camera is locked. The viewfinder doesn't show an image and there is no button to press that will take a picture. There is a large yellow dot to the right of viewfinder and when tap it it enlarges the camera. The shapes below the viewfinder do not rspond to touch and to the left of the viewfinder there is a vertical lozenge shape that exposes a view of the film. It doesn't respo nd to touch either. I have successfully taken 19 pictures but now I can't get the hipstamatic to work?

There seems to be two separate issues here. I'm going to assume you have a charged battery pack in the camera.

First, the screen. Turn the camera on. Do you see the menu when you press the MENU button? Does the shooting info show when you press the Info button? Can you see previously taken photos when you press the Playback button? If none of those show up then something is wrong with the screen (or the battery is dead).

Second, the viewfinder. First, make sure the viewfinder in the back is clean. Now turn the camera on and look through the viewfinder. Do you see the eleven focus marks? Do you see the info at the bottom? Now turn the camera off and remove the lens. Don't touch anything inside the camera! Do you see a mirror at a 45-degree angle? Is it clean? Look at the focusing screen above the mirror. Is it clean? Now look through the viewfinder and point the camera out a window. Do you see a more-or-less white blob, or the same grainy dark film?

Have you tried pressing the display button ? It should switch from LCD to viewfinder.

There is no repairs possible by you, the choices are these, send the camera back to Fuji for exchange (expensive) or replace it.

I presume you're asking about a Digital Rebel and not a 35mm film Rebel (as per the question heading).

If so, that's probably normal. It's only relatively recent dSLR models which have a "live preview" facility (often wrongly called "live view"). The whole point of an SLR is that the viewfinder is the main compositional viewing tool; the LCD is there solely to display and adjust camera functions and to review images already captured.

Most current and recent SLR's now have live preview, and all true SLR's are incapable of viewing the image at the actual moment of image capture as the viewfinder mirror must flip up out of the way of the image sensor.

If you want live preview then you must change your camera. if you tend not to use the viewfinder anyway then consider mirrorless Compact System Cameras such as the Olympus and Panasonic Micro Four Thirds models as they do have a true live view capability and the LCD is the main (or only) tool for composing images. Panasonic also have their regular Four Thirds G range, which look like an SLR but have an electronic viewfinder and they are also capable of true live view.

Sounds like you just accidentally pressed the DISP or DISPLAY button on the back of your camera. This turns the screen on and off in photo mode to save batteries (you'd then use the optical viewfinder in its place). Just press the button one more time with the camera turned on.

This model only lets you see the image in certain modes. Test if it is properly working by changing the image mode to "P" and pressing the "Set" button (its in the middle of the arrow keys if you're having difficulty finding it. That should display the image on the LCD screen.
If that doesn't display an image, press "Menu" (upper left hand corner) and press the right arrow 4 times to get to the wrench with two dots menu (says "LCD brightness" on the first line. Press down 5 times and select Live view function settings and press "Set". Make sure the first line is set to enable. This should resolve the issue.
Please leave feedback if this was helpful, thanks.

You cannot take a picture when your camera has not been focused yet. This is done by pointing your selected focus point on your subject, then click the shutter button halfway / half-pressed until you here a beep or see a dot on the lower left portion of your viewfinder. Once you have locked your focus, press the shutter button all the way down to take the shot.

Sounds like you accidentally pressed the DISP (Display) button on the back of your camera. This manually turns the screen on and off in picture taking mode to save battery power. You could then use the optical viewfinder in its place. To turn it back on, just the DISP button one more time.

On the back of the camera to the left of the "BACK" button is a button with a picture of a magnifying glass in a rectangle. If you press this button you should lose the zoom box!! Hope this helps!

There are a couple issues related to "slow" that I have with my C-750, and this is how I get around them.

One is the write speed to the xD card. This can prevent you from taking sequential pictures quickly, as the camera displays the current picture it is writing until it finishes. You can make the image of the current picture go away and use your viewfinder again, while the camera is writing the picture, by pressing the shutter button halfway and releasing it. Then you can see your subject in the viewfinder again!

Second is the delay between the time the shutter button is pressed and the time the shutter actually opens (when the camera actually takes the picture). This can be fixed by lining up your shot and pressing the shutter button halfway and holding it for a few seconds. This will give the camera time to adjust and lock focus, shutter speed, etc. There is a small green dot on the display below the battery indicator which will blink a few times when the button is pressed halfway, then remain on steady. When the green dot is steady, the camera is ready. Press the shutter button, and the camera should immediately take the picture.
