The area of interest is D18, U28, FB23 and U29. I can't tell if there is any damage because you are using a single light source which leaves shadows. Q1 may be a switch and I think U28 may be a set of 3 diodes. I can't read what U29 is but if it connects in any way to Q1 and D18 then it may be the LCD control chip.
If it is you will need a data sheet to tell which pins are which, somewhere there should be an inhibit, or switch, line that is the one you are looking for to find out its state.
I would like it to be something simple like D18 being open bit it most probably isn't.
One thought, if you sort this out you might have the answer to the WSOD that is bugging some people.
