WHEN I PUT MY PHONE ON THE SCREEN COMES ON AS NORMAL BUT I CANT USE ANY KEYS AND THE LIGHT COMES ON IN THE BACK FOR THE CAMERA AND IT STAYS ON .THE PHONE I HAVE IS SGH-G600

If your camera is in display mode, and the screen stays dark, check the memory settings. (internal / memory card)
Put the main dial to automatic and shoot a picture, to see is anything comes on the screen.

Its a screen light problem I guess. Have the screen replaced and your phone is back to normal. Instead of trashing it, you can put it on say at ebay. http://deviceteck.com http://deviceteck.com/

just visit motorola service centre, there is a problem in its FPC cable

To easiest way to fix this is to go back to the company you brought the phone off as it is a problem within the phone hope this helps...

IS THE RED LIGHT THAT IS STAYING ON THE BATTERY LIGHT? IF SO IT COULD BE AN ELECTRICAL FAULT, AND IS NOT FIRING UP THE ELECTRIC FUEL PUMP

the flexcable on the phone needs to be replaced take the phone to amobile service center and have them fix it for you.

well for the reset to work the phone has to fully charged or atleast 75% charged. 1. pull battery out. 2. press and hold center navigation button. 3. put battery back in. 4. press and hold power key( red end key) until keyboard or screen lights up then let go of power key. 5. continue to press center key until a black screen with green lettering comes up that says master reset.

your phones' firmware is corrupted and it needs to be reflash , so take the phone to any mobile service center or mobile tech and have them reflash it for you for a small fee

If it says "back" as an option on the right lower part of the screen, have you tried clicking on it? Mac

just clean the video head and you will get the image.
