errrr naaaa ... with the complex address / data / strobe / backlight multiplexing, you'd really have NO idea of what signal you were interrupting.
PLUS it may knock out a whole set of other signals. EVEN if you had a 4 channel DSO and captured waveforms etc, aligned them to figure out sync / data etc, it is still really a waste of time. This LCD is software driven, from that MPU, so who the heck knows how they generated the signals. Next patient please ...
Had it have been an "off the shelf" LCD driver, you would have had a damn good chance, but custom ... naaa

Having a socketed(!) flash is definitely the opposite of a cheap highly cost-optimised design, and there seems to be plenty of documentation on the VC0706 that it uses (it's popular enough that Adafruit is selling (overpriced as usual) stuff with it), so I'd consider this quite a hackable design.
OwO:
A 40 pin LCD is almost always going to be a parallel interface LCD. The data interface usually are all the same and consist of sync signals (usually either HSYNC/VSYNC or EN) and RGB lines (24 signals). The place where it might differ is the power rails, some need negative rails or +22V rails.
JamesAtCriterion:
Thanks again all, I think that the answer here is that this is beyond my current level of skill, and I should start with a smaller project :)
I think that I will hold on to the parts, and put them in a box marked "when I have more skill and time to play with".

Thank you again, everyone for all your input, it has been great.
This has been my first post on this site, and I am so happy with the positive feedback I have received, very happy to be part of this community! :) <3
digsys:
I do agree with amyk that "I'd consider this quite a hackable design", for "us" that have been around a bit, or had some practical experience, but it is only a guess that it is standard. At minimum, you'd need a 2-4 ch DSO to understand it properly. Definitely start with "simpler" stuff. Happy hunting.
