4000 D only show white screen

[Ihza]

I hadn’t used my camera for a long time, but recently, I wanted to use it again. However, the screen only displays white. The shutter button and lens work normally when there’s no memory card inserted, but when I insert the memory card, the camera won’t take pictures. any answer would help me

Ihza,

While I can't be certain, it seems to me that if you turn your camera on and the screen is white, it means that there is no lens attached.

I think that you can use the shutter and the lens, even if there is no card in the camera, it's just that you won't be able to store any pictures. If you insert a card, and the camera won't take a picture, you probably have a bad card. I'd try re-formatting the card you have, and if that doesn't work, get another card and try it again.

Thank you very much for taking the time to respond, Steve. I really appreciate it. However, I’ve discovered something new: the memory card still works in the camera, and when I take photos and transfer them to my PC, the images only appear black. Yet, through the camera’s viewfinder, I can see the visuals clearly.

Ihza,

When you look through your viewfinder, you are only seeing what your lens is seeing. You haven't taken a picture yet.

When you look through your viewfinder, do you see a graph running across the bottom of the screen?

The little arrow should be centered on the 0 in the middle. By changing your settings, you can move it left or right to make your pictures darker or brighter. If your pictures are coming out black, it probably means that your shutter speed is too fast, or your ISO is too low. Leave your aperture in the middle somewhere like f/5.6 or f/8 and try slowing down your shutter speed, or increasing your ISO and see if your pictures get brighter. The object is to move that little needle back to the center.

What shooting mode do you use? Av (aperture priority), Tv (shutter priority), M (for Manual), P (for Program mode), or Auto?

Just for the heck of it, for a little while, go outside on a nice sunny day, and put your camera in P Mode. Your camera will select the shutter speed and aperture for you. Take a little notebook with you and jot down the settings the camera chose for different situations (bright and sunny, something in the shade, etc. If you feel that your pictures are a little too dark, increase your ISO a little. If you think they are coming out looking too bright, lower your ISO a little.

After a while, you will begin to get a feel for what kind of settings to use in various situations.

Screen being all white is not indication of a lens being absent.

Press the Menu button. What do you get? Anything?

It really sounds like your camera has problems and needs to be checked out at Canon.
