The doe problem go away if you bang on the side of the camera? there is a known issue with the CCD sensor on certin model cameras that after a few years the glue or somthing dries up inside the sensor and it developes a bad connection. Canon has admit they know about this problem and they will fix them free of charge and pay shipping both ways. Sometimes users can bang on the side of the camera and the camera will work properly again but not for very long. I cant see your display so im not sure if thats it or not but the problem has this purple blackish symptom. Go to the canon usa webpage and then search around for your camera model and if there is a known issue it will say on their site. Then there are ways to contact them on their site.

This is a symptom commonly listed for DiMAGE cameras listed on EBay for 'parts only'. Dropping the camera I had caused the same problem and carefully 'smacking' the camera once again did solve the problem but that may have been dumb luck. Sorry but it is a service task that may cost more than the camera.

SOURCE: nikon d40 not working and focusing

I have similar problem on my D40. I think there is something mechanical with the camera's shutter button, some connections, I guess... The only solution I've found is to go to Menu > Custom Settings Menu > "AE-L/AF-L" and set to "AF". Now you can focus by AF-L button. Focusing works then perfectly. The WORST thing is that I can't lock exposure now and that's sad :( Maybe I can try to fix this in the camera center later, we'll see. But it takes months in Ukraine to do the fixing... Hate that!

SOURCE: Automatic focus not working

The D40x only autofocuses with the latest AF-S (and old professional AF-I) lenses. Most traditional (screw-type) AF lenses from 1986 through today will not autofocus on the D40x. If your lens says "AF-S," you're fine.
Most lenses sold today for the D40x are AF-S, and so is the included 18-55mm kit lens. Many non-Nikon lenses from Tamron, Tokina, Quantaray, Sigma and anyone other than Nikon still won't autofocus on the D40x. Try before you buy, but honestly, there isn't much the included 18-55mm lens won't do.
Autofocus systems are fast, but not usually instantaneous. You have to hold the shutter down halfway as you compose the first shot so the AF system can focus and lock, and then the camera fires instantaneously when you press the shutter the rest of the way. See Preventing Shutter Delay for more.

SOURCE: hi, my olympus FE-290 suddenly went black.

I just solved the problem. The lens system wire connector to the main pcb was out of this female conector. Only you need its disassemble the camera and in the back of the lcd there's the conector, press it with carefully and test your camera.

BE CAREFULLY WITH THE LCD WIRE WHEN YOU TURN IT.
