Black screen i have a cannon sd750, i got it for christmas.  everything was fine up until the last couple of days.  the screen would turn black, i would be able to play with it and the picture would show but now its pitch black, but i am still able to take pictures, i just cant see what im taking a picture of until i download the pictures.

also make sure you're not in presentation mode, my vostro (winxp) would randomly boot to presentation mode and turn off my monitor....
upgraded to win7 and it stopped doing it...

If it has not corrected itself by turning the phone off and taking the battery out for a couple of minutes then turning it back on you should try a factory data reset. In Idle mode, open the application list and select
Settings - Privacy - Factory data reset - Reset phone
-Erase everything.

when u turn on your laptop press F8 and hold find the 1 that says last know configuration ok try that

best thing to try is a external monitor if one is available - if not then run the test....turn system off..as soon as u power back on hold down the FUNCTION key..wait till u see the test running on the screen before u let go of function !!! it will only take a couple of min to know .....when u see this test run just wait until it asks u if u see color bars..whether u can or cannot does not matter..we want to press N for no on the kb....next u will get the color bars if u can see them the mb is fine and u need to replace the lcd..if no bars were seen then u replace the LCD

Think that you accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

I had the same problem until I realized that you can't have the dial selected on Auto. Move it to M for manual and it will shoot continuously.

Follow the steps below, Hope this helps

1. Try another Av cable ( Audio video Cable )

2. This issue is caused by the video card inside the xbox 360. If you still have warranty better send it in for repairs ( Call xbox customer support )

Good Luck

Just take a new one...he...he...he

After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.

Take it back to whoever TRIED to fix it.
