I would check the caps with ohm meter. Make sure they all show increasing resistance. Caps can be bad without looking bad. Check output voltage on the power board, should be around 12V. If all that checks out then I'd look next at the backlight bulb. I'v repaired many monitors and the problem was almost always overheated caps on the power board. Post back and let me know.
Testimonial: "Amazingly fast and helpful response. Follow-up help needed and posted as a comment."
Okay. So on the caps with no increase in resistance double check by reversing polarity for a moment and then back again. Sometimes a good cap will store charge well enough that when you do this test you see no increase in resistance because it is already 'full'. If you still get a negative reading on those then I would replace them. You'll need to have a solder remover and a fine tipped soldering iron. Go slowly and gently until you get the hang of it. Too much heat can damage the board. Good luck

First: Thank you for such a quick response! With just the power cord in, these are the results (multiple checks).Voltage (starting from the black wire next to the blue wire) the 8 black wires are
1- 0
2- ~15.6
3- ~15.6
4- ~15.6
5- ~10.6
6- ~10.6
7- ~15.6
8- ~15.6
Caps
c107 - no increase
c108 - increase to 4.0
c109 - increase to 4.0
c110 - increase to 4.0
c111 - no increase
c112 - no increase
c113 - increase to 0.905
