It appears that someone has resoldered (?) the "ROM" at U12. Are you sure it hasn't been damaged?
If you have a multimeter, measure the voltages between ground and each of L1, L2 and D2 (above the SMOOTH chip). Use a screw hole as your ground reference.
Also check the TVS diodes.

I somehow do not see any damage to the TVS and the Zero ohms resistances ,Your observation on the ROM being soldered is correct
