[jack4566]

I got a jtaged falcon MB xbox 360 today to work on , I didn't do the jtag , so
I dont have the original nand image, it has 8955 dash , it boots up fine, and reads the game fine

My problem is when it loads the game and starts in to game play screen go black or has white lines down the screen , this is with no hd hook up to it,
this is with the original game disk , that work fine in other xboxs

thanks for any help

I would say it's the ANA chip or console getting near RROD, most likely nothing to do with the JTAG it self.

Try playing some movies or XBLA games of the hard drive and see if the console displays the same behavior!
