Dell 1702FP Blank Screen problem

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: http://www.robbruno.net/dell1702fp.wmv

Hi there, 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: http://www.instructables.com/id/ELWXF03NV6EQZJIZM2/ Enjoy it! Koray.

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. http://www.archivesat.com/TV_monitor_schematic_tips/thread717033.htm Dell 1702FP LCD Monitor with front flashing LED's dickens_cider64 wrote: 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. 2006-05-09 18:02:48 --- In Tv_monitor_schematic_tips@yahoogroups.com, Ardell Faul wrote: > > A lot of them have a bad 10 uf SMC.
