I cannot help you with the problem, but
- your photo skills are way out of range. The only thing I can tell is that this is some HP laptop;
- Pins 3 and 9 are available probably on ten different places on that motherboard;
- if you provide exact model of the laptop, and any markings on the motherboard, someone with more knowledge might be able to help.
Sorry the megapixels on my phone aren't that high and the focus for closeups usually sucks. https://imgur.com/a/DNYuY
I just want some general advice on where to put the multimeter probes to start testing the circuitry and components related to internal video. A schematic for 744603-001 would be nice then no Pic needed.
