Hey all.
Basically I have an M190A1 touch panel from a defunct HP iQ790. A few years back I had a HP W1907v, and used the touch panel and its controller board to convert the W1907v into a touch screen.
The panel has two cameras, one at the top left and one at the top right, each with their own lead running to the controller board via zif connector. If memory serves, each lead has about 7 connections running from it.
All went well when I got it back together, was very pleased with the result. Until I found out the top inch or so of the touch screen doesn't respond to touch properly. The touch overlay is a Nextwindow 1950 panel.
It acts as if one of the cameras stops working intermittently - the touch responds but rapidly jumps around from one side to the other, and even when it doesn't, it's very very shakey.
So I pulled it apart again, and found one of the leads appears to be slightly damaged. One of the gold pins is missing its tip, but not all the way along, most of it is still there.
I'm pretty sure it's still making contact, but I cannot think of any other explanation as to why this is happening. Has anyone had any experience with one of these touch panels? What would be the easiest way to repair the damage on this zif connection?
I'll get some pictures up later, only pic I can find right now is this one, of the controller board: http://i.imgur.com/gr32ohul.jpg (One of the zif fasteners is missing I know, it was found and later reattached to the connector)
Cheers!
