Nokia 3650 Black Screen

[oltadmin]

I have a 3650 and it got some dirt in it from work so I decided to take it apart and clean it with some electronics cleaner. I have used the stuff before with no problem but after the phone had dried off I put it back together and now when I put it the battery in and push the power button the screen turns black then fades back to white and that it no noise or anything.

Can some one please help?

Make sure the lcd connector is connected right.

Thanks for your help. I know this is not what fixed the poblem but it is what I did different when turning on, I inserted the sim card and memory card and suddenly it worked fine. So what ever it might have been and it probably was the connector had dirt in it from what got moved around after I cleaned it, it is fixed.
