My Camera screen shows lines flickering, how can I fix this?

Try using a laptop to connect to the monitor. That will prove whether it is the monitor or the PS4. If you don't have one, ask a friend to come over with theirs.

If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

Can you check the function buttons and make sure the primary display is set to show the output on the laptop. Try repairing your OS. If not then re-install the os. As you are saying till the time windows gets loaded, all works fine so it seems the issue isn't really the hardware.

Please check the line voltage 220V AC and check the earthing voltage 3V AC..

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, 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 the following for further info and a simple fix that may help:

Just ring them up, send out your camera and in a week or two it comes back working fine! I have done it and can say that JVC support is A*

Your camera likely needs a new CCD imaging sensor. It is a cute little thing and is very expensive to replace. I've seen deals to repair any digital camera on eBay and I would check for a local repair person in your area. You can use the search on this site to see who might be close by. I have an A310 doing the same thing.

This could be early signs of imminent failure of a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:

This is a component failure
If the camera is less than a year old return it to the seller.
If older than a year but a current model contact Sony who may replace it free of charge.
There have been recall on some models because of component malfunction

To resolve the annoying "change the batteries" problem. Goto menu, choose yellow menu, select
file No. reset to ON. Turn camera off and back on.

Voila fixed.
