Dell 1800FP, no signal found (analog). Green LED on, get message
When I power on the monitor, it does not receive the video signal, I get the box that says no signal. This tells me that the backlight works. I checked the power supply and found all voltages present. (from top down, GND, GND, 5V, 5V, GND, GND, 12V, 12V). What could be causing the screen to remain black?

Check if your signal cable is properly connected to your system unit and make sure that non of the pins of your signal cable is broken.if any of the pins are broken,try and change the whole signal cable and re-connect it again
after following the above instruction,reboot your computer

disconnect the signal cable from the computer. if it shows color bars, it means your monitor is ok and your video card is faulty. if it still does the same thing. you need to reseat the video card if its not integrated.
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
It could be a setting problem, power saver setting, or a mode that the monitor does not really support - things like refresh rate - or actual hardware.
Easiest way is to borrow another like monitor, and say another video cord and see if the problem remains, or if a newer monitor says 'out of range' or similar.
Then, if you have a fancy video card,remove it and use something primitive. Not reading instructions is a big cause.
If its not a setting issue, and as the inverter board is ok; if the above description is correct, reseat the inner board connecting cables.(wood fires and seaside locations) If not that, a lucky guess might be the electros on the logic board.
