When I turn on the phone and logo appears it has light and when logo desappear lights goes off. Then I put phone at rest for 20 seconds and press some key and lights goes on for few seconds and then again off.What can be the problem.

same problem here . the lcd works fine but something else causes the phone to show the pic only for a few seconds . after some time it works again and then off again . @ wong java - a pic would show nothing as either the lcd is normal or off

In many cases there is problem on the keypad Flex connector, same track described with red line on the MB, but on other side (flex). Try it, maybe help!
