can you damage the screen of an N2 if you solder the 2 pins on the bottom of the board? Or is it really only the ribbon cable?

 

The N2 was repaired by United Radio in 11/06 they replaced the board and the cable. I got the unit 1/07 and soldered the 2 points. I just put it in yesterday. At first the screen worked fine. Then when you went to close it it would black out. Then it went completely black.
