The screen is white, nothing shows up on it - Sony Cyber-Shot DSC-S40 Digital Camera

Make sure the video/audio cable is plugged in correctly. Red cable into red socket, yellow into yellow and white into white. It is easy to put these cables in the wrong socket by accident and will cause no image to appear on your screen.

Did your phone drop on the flow? Is it just showing white and still works ?or Display white screen and not working?

For a phone to display a white, does questions need to be answered..

If it fell on the flow it's usually a screen fault and it needs to be replaced.

If it didn't fall down, but displays white screen and nothing function,it a software faulty needs a memory restoring..

If just showing white screen and you still can make calls with it, then it's screen fault needs to replace..

the problem is that your chip is probably cracked and it is not allowing your screen to show up

I was getting a white screen every time I put the power on and used the suggestion by Fionn - squeezing the camera around the screen and it worked like a charm.
Please try it also

had same problem on a n80 slide phone :found the ribbon conector in the phone had a split so only showed a totol white screen
Replaced ribbon cable and all was fine priced at only a few pounds

put it in DFU mode while connected to the computer. to do this, hold the home and power buttons for 10 seconds and then let go of the power but keep on holding the home for 10 secs. the screen will be black and nothing will show up. go to itunes and click on your ipod on the left. then click restore. this should work.

Mine too!
It beeped three times, then went black. then went white and now won't do anything! ahh!

check the screen connection or get a new 1

Your memory card is corrupt. Try a new, known good one. I had the exact same issue that you are describing and that did the trick.

just re format your fon for highest version
