The inverter board are two parts to the devastated(description is unreadable) and I do not know what they are.

Q4 is a 16
Q5 is a 26
talkingelectronics.com/projects/SurfaceMount/SurfaceMount-P1
Note that Q4 also has a 22 marker on it turned 90°, smaller print but Q5 has 26 in both places.
From that website, it would ID as
Q4 = DTA114EKA, or DTA123EKA
Q5 = DTC144EKA
These devices are part of the DIM and SLP (Enable) input conditioning to the OZ960SN.
The SLP line seems to be a TTL input value (0-5V) While the DIM is a linear voltage sent by the other board to value the brightness setting and hence the PWM of the inverter CCFL lamp driver.
