Having problems with your Dell UltraSharp 1702FP 17" Flat Panel LCD Monitor ?

Dell 1702FP Blank Screen problem

\015 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:\015\012http://www.robbruno.net/dell1702fp.wmv\015

Hi there,\015\012\015\012I 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. \015\012\015\012Solution: replace surface mount capacitors, 10uF 16V value, C604 and C507...\015\012\015\012I created an instructables web page for it, so please follow the link below:\015\012\015\012http://www.instructables.com/id/ELWXF03NV6EQZJIZM2/\015\012\015\012Enjoy it!\015\012\015\012Koray.
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.\015\012\015\012\015\012http://www.archivesat.com/TV_monitor_schematic_tips/thread717033.htm\015\012Dell 1702FP LCD Monitor with front flashing LED's \015\012\015\012dickens_cider64 wrote:\015\012There 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.\015\012\015\012I've narrowed it down to the A/D board. \015\012\015\012I've checked/replaced the electrolytics. Is there anything else I\015\012need to check? Voltage regulators? Transistors? I don't have any\015\012schematics or block diagrams for this unit so I'm kinda winging it\015\012based on my LCD experiences but this A/D board is a little more\015\012complex than my others. \015\012\015\012Any help would be appreciated.\015\012\015\012 2006-05-09 18:02:48 \015\012\015\012\015\012--- In [email protected], Ardell Faul\015\012 wrote:\015\012>\015\012> A lot of them have a bad 10 uf SMC.
