And I've repaired a few by routing replacement wires for the traces that broke. The downside was that after hours of disassembly, finding the trace with an ohmmeter, the repair only held up until the next trace on the flex cable broke.
You'll want to replace this cable and you'll get it from Dell.
Time to call them.
I have a Dell Laptop with a slight problem. When I open the screen about 3-4" it's fine, but if I open it further the computer beeps once and the screen turns white. I'm assuming that it's an LCD cable but not sure. I was thinking of buying a cable then installing it myself (which I have never done before). Anyway, my two questions are: Is it safe to open the laptop when it's not plugged in and no battery attached? Can you be shocked? Also, does this sound like a LCD cable problem? Any help would greatly be appreciated.
