When powered up the LCD screen displays a series of black lines flickering up and down the screen. Same also in the view finder. Can still access the menu setup.

I know it may sound like the shutter is moving, but you're going to have to actually look down the lens barrel to confirm it's actually moving, and not just producing a sound effect from the camera. Also keep in mind Canon's SX IS series cameras are notorious for the following problem (fantastic cameras otherwise).
A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Hi, are you having issue on camera LCD screen that it will not show anything on the screen? Kodak Easyshare C813 has no feature to turn the LCD screen Off only Kodak Easyshare Z series and some M series that has a view finder that you can switch the LCD screen off and just use the view finder to save battery power.

You can refer to Kodak Easyshare Manual check this site http://www.kodak.com/global/en/service/publications/index.jhtml?pq-path=1398#otherDigitalCameras

VIDEO DRIVER FOR LATITUDE

the video playback is sampled off the video out and independently processed sorta like a TV signal to project on the lcd screen.
horizontal lines means you lost sync circuit and needs troubleshooting. Hopefully maybe a bad connection with a ribbon cable for the ICs and components are hard to change and jammed tight. I would order a video board.

hi

the 400d has a sensor just below the optical view finder
it detects when you face is near the view finder and turns off the lcd scren

the display button (top left) can manually turn the lcd on/off

refer page 101 of the manual to modify this setting

what is the model number? if it's 10 years or older you are most likely dealing with bad surface mounted capacitors.
