I have two 1702FP's not displaying anything. The three LED's in the front just cycle on and off like it's trying to power on but resets. The Power LED never turns Green, it just stays yellow and flickers. I made a video of what it's doing:
I had the same problem on two Dell 1702FP monitors and I solved them, now I am using one as an LCD TV and it's been working great since then.
Solution: replace surface mount capacitors, 10uF 16V value, C604 and C507...
I created an instructables web page for it, so please follow the link below:
I found this on another forum. I have a 1702FP doing the same thing but I've not dug into the solution yet. Sounds like I need to pull out the soldering iron.
Dell 1702FP LCD Monitor with front flashing LED's
There is no response from the front controls. No display. This fault exists whether or not the video cables are plugged in...(no self test). All the cables inside are connected correctly, no bent pins etc.
I've narrowed it down to the A/D board.
I've checked/replaced the electrolytics. Is there anything else I
need to check? Voltage regulators? Transistors? I don't have any
schematics or block diagrams for this unit so I'm kinda winging it
based on my LCD experiences but this A/D board is a little more
complex than my others.
Any help would be appreciated.

Are you referring to the smd 'cans' C507 and C604
they say K1W 10 16V? or am I looking for a 'chip' capacitor?

If you have another monitor for desktop hook other monitor up then under hardware and software in control panel, add the dell monitor, then hook it up. Some operating systems need the driver to be added first. My brother almost threw away agood dell lcd monitor before I told him this, now he loves the lcd, works great.
It might be a failing electrlytic or a heat-related issue with a transistor in the power supply, or it may be a problem in the video board.
Sounds like will need good old-fashioned component-level troubleshooting.
