AVIC-N1 Part Number Request

Can anyone confirm that if I had this problem on my AVIC-N1, the system would still make the sounds when I touch the screen?  The screen is completly blank on my unit and when I touch it, it makes the sounds as if it were still working.  Also, when this problem started happening, it was not consistent.  Sometimes the screen would turn on after sliding out, other times it would not and now it is not on at all.  Does it sound like replacing this part on my unit would fix my problem?

I doubt its the backlight.  My problems only started about a week ago.  At first, when the unit turned on and the screen rolled out, the screen would not be on, but if it pushed the button that sends it back into the unit and bring it back out, it would be fine, but after a few days of that, it just stopped working all together.  I am 99.9% sure its the flex cable as this sounds to be a common thing that is happening. 

So, it requires a lot of disassembly to be changed out?  I could do it, but would not feel too comfortable if I had to take the whole thing apart.  What if I pulled the head unit out with the screen out, would that help so I wouldn't have to cycle the motor drive?  If its a big job, I'll just pay the guy off ebay to fix it.
