5 Non working LCD display. (Electrolysis Damage)
I have an Ipod nano 4th generation with a non working display. On releasing the ZIF connnector I found the screen ribbon had corrosion damage on a couple of the contacts(inside the connector.) I'm a bit surprised at this because this stuff is gold plated. One piece of track had completely disappeared.
Does anyone know a way of repairing this or is it a scrap mainboard?
Update (09/24/2010)
Thanks for the suggestion but the damage is on the plug part,(ribbon attached to the mainboard) The display has the socket half.
I remembered a good many years ago using some conductive silver paint.
Have been able to get hold of some so will give it a try. will just have to make the smallest possible blob with a toothpick, then scratch the print away with a fine sewing needle.
Bu iyi bir soru mu?
did you succed?

No, I gave up on that one. The shape of the contact tongues is complex. They do not run in straight lines so would be very difficult to scrape out with a chisel ended sewing needle.

I also have several ipods with this problem, would love to find a solution for this.
I have used silver conductive paint but no sucess.
I keep thinking if there is a way to cut the faulty riboon and attach a new one.
Maybe with a specfic connector...
