That soft buzzing sound seems to me would be the power supply inside the camera trying to operate something under a loaded condition like maybe ba stuck iris or lens or could even be those small caps (we call them Pan caps)inside your camera are starting to go bad. unless your quite good at micro electronics I would leave this one for the pros.. Contact the sony service depot in your owners manual.

No picture on LCD monitor when camera (rebel xt) is turned on

I am not sure what is the problem. You say no"picture"..is the screen totally black? Even when you try to preview photos in your camera memory? If so there is a problem with the hardware, LCD screen battery, or some other part.

If you mean you only see numbers and photo setting information on the LCD, that is normal for this Rebel models. The picture only appears in the viewfinder. It does not have a "live view' function to switch the image from the viewfinder to the LCD while you are shooting, as later model have. I have such a model and it is very disappointing.

No image is available to view on the lcd screen canon ixus85is

Click the "disp" button. The display of the camera has been turned off in the LCD screen but you can still use the viewfinder, this functionality is just for those who prefer to use the viewfinder instead of the LCD screen.

FUJIFILM FINEPIX S5000.No image on viewfinder or LCD.

I think there is a small button on the back of the camera near the bottom that turns the viewfinder off and on I think. It should be in the manual.
It might have gotten bumped while in the bag.

S1IS canon camera

Hi,

Apparently the vendor-supplied CCD image sensor used in this Canon digital camera may cause the following malfunction: When the product is used in recording or playback mode, the LCD screen and/or electronic viewfinder may exhibit either a distorted image or no image at all.

To determine if the CCD (image sensor) is working properly, follow these steps:

1. Insert a memory card with known good images on it into the camera.

2. Power the camera on to the Playback mode.

3. Press the DISPLAY (DISP) button to enable the LCD panel, and observe
the LCD.

a. If the images are displayed properly, please proceed to step
four.

b. If the images are not displayed, or a "NO IMAGES" message
appears, please ensure that the memory card contains known good images.

c. If the card contains known good images, and the issue persists
with a second memory card, the camera will require service.

4. Switch the camera to the Camera mode. You may use any shooting mode
(i.e. Auto, Manual).

5. Press the DISPLAY (DISP) button to enable the LCD panel.

6. Point the camera at a well-lit scene and observe the LCD and/or
viewfinder. If the scene the camera is pointed at appears on the LCD
and/or viewfinder, the CCD is operating properly. If the LCD and/or
viewfinder remain black, the camera requires service.

Effective immediately, and regardless of warranty status, Canon will
repair, free of charge, products exhibiting the above-mentioned
malfunction if the malfunction is caused by the CCD image sensor. Canon will also cover the cost of shipping and handling in connection with this repair.

Regards.

LCD is not displaying

I am not familiar with this particular camera, but if there is any other form of viewfinder on it, there is probably a way to switch the picture back and forth from the LCD display to the viewfinder. Personally I would not buy a camera without a viewfinder, but right now, the only companies who make cameras with an optical viewfinder are Canon and Sony, and even they are getting away from it! Shame on them!

The other type of viewfinder that works well is the type that reads the CCR image onto a smaller screen to use as a viewfinder, like my Kodak Z712, or the Nikon P-80, I think it is, with the 18X Zoom.

One of my issues is that I like to take available light photos outdoors at night, and the LCD screen simply is not bright enough to show the image, even though the camera is able to make a decent photograph in that light.

Most cameras will let you shut the LCD screen off to save battery power, so you will have to find out what every button on the camera will do, and make sure that the screen is powered on. It may also be that you have to recharge or replace the battery in order to have enough power to turn the screen on.

Of course, as we say in the computer world, RTFM! Most of your questions will be covered in the manual, so read it from cover to cover, with the camera in front of you. I was a freelance photojournalist for two decades, and trust me, there are still things I won't know about a new camera without either reading the manual, or experimenting.

LCD Monitor on ,and the Electronic Viewfinder turned off

If you turn on the back LCD, the electronic viewfinder will remain on while in a shooting mode. There is no setting on the camera to use only the back LCD monitor while shooting. If you playback images in the Play mode, only the LCD monitor will turn on. However, if you press the Monitor button while in the Play mode, than the back LCD monitor will turn off. The image will display only in the viewfinder LCD.
