    I am working on a Samsung SyncMaster 170MP. When plugged in the green on/off power button light flashes continuously and the screen never comes to life. I've tested the power brick and the outputs (14V @ 3.5A) are good, I also made sure that the PCs' video cable output is good and it works fine when plugged into another monitor. I had a similar problem with a Dell 1702FP and had to have (2) capacitors replaced on the power supply board. (10uf - 16V).

    I just received the monitor from a user who discovered it did not work and bought a new LCD monitor.
    The power brick seems okay; all LEDs and buttons on the front seem to work.
    I plugged in an audio cable and sound is working okay.
    Tried 15pin PC input and Video input and the screen stays completely black.

The inverter board has probably failed. Mine turned out to be the clamping diodes on the inverter. It would act like it was firing up but shut down just as the screen would normally come up. I replaced the diodes and it fired right up and has been working great since.

Hummm. Try to unplug everything, reconnect, than restart. If not working, try to plug your monitor on a different computer to diagnose what is wrong, the computer or monitor. It could also be your graphic adapter, verify that it is firmly attached to the motherboard.
Lastly, replace the defective part.

It sounds like it since you have the 14v going to the inverter. Repairing inverter boards even on lcd's is 50/50 shot, so let's give it a go. If you have a dvm check the ohms on the inverter xformers ( if more than one) they should be identical in resistance. Check or replace all electrolytic caps on the board. That's about all you can do outside of replacing it, Oh, see if you have a 5v source going to in inv. bd also, check that.
