Question about Samsung SYNC SGH-A707 Cellular Phone

1 Answer

Samsung A707 SYNC. No main screen display

The phone is apparently working. Getting calls and can make calls if I dial blind. The large screen flickers and has a dim glow, but does not display anything. The outter screen works fine. The phone has not been wet or dropped. It was working this morning and now it's not.
Any suggestions?

    I am also experiencing a similar problem on an intermittent basis. At times when I open the phone after it has been on a while, the main screen is blank, but other times it is fine. Additional symptoms include occassional lines scrolling up and down the main screen before it dims out completely. Also, on occassion the screen will come on upside down and reversed, so that I would have to hold the phone upside down and in a mirror to read it.



    The response to the previous post was to replace the flex, but how do I take the phone apart and replace the flex?
