What is causing this backlight problem on my iPod Nano 4th Generation?

Texto:

I got an Ipod Nano 4g which I bought faulty on ebay.  Faulty meaning the screen was dead.

I have now replaced the screen (bought a new one), it is working, except for a missing backlight.  I have spent some time trying to figure out what can be done and I am a bit stuck.

I think the unit has had water damage, I say this because the display ribbon cable has signs of corrosion (on the second connector from the left-to be specific).  I have used contact cleaner and cleaned up the cable as well as possible. However no luck - the screen backlight is off.

Do you know/think a bad ribbon cable could cause a backlight problem?

I don't see signs of corrosion anywhere else on the logic board.  Steve, in your [http://www.ifixit.com/Answers/View/14137/Screen+works+fine%2C+but+no+backlight.#answer14161|post], you say if it isn't the screen it self(or the cable), then it is failure of the circuit powering the screen's backlight on the main circuit board. What exactly could be faulty on the logic board - is there some way of seeing it? How come only this circuit fails while everything else works perfectly.

All the best!
