Blinking Orange LED light on E151FP monitor

After having my computer and monitor off for about a week, I turned on the computer and monitor yesterday. On the monitor there is a brief flash of light, and then the screen goes blank, meanwhile the LED light flashes orange.

I have checked all connections, turned the monitor and computer off and on several times, but the problem persists.

Please advise,

Thanks,

Dave Thomas

This monitor is know for a lot of parts that go bad, luckily they are usually the same ones.
If you are a technician or know one who can help you. Below is a list of part to repair/replace once the case is opened. (dont try this if your unfamilier with working on electronics.

1) F601= 2A Fuse
2) C605= 68uf 400v (must change)
3) R615= 0.68ohm 1watt
4) Q601= SSS6N60A
5) R613= 1Kohm 1/8watt (value changed to 2.3Kohm or higher)
6) R623= 4.7ohm 1/8watt (value changed to 7.2ohm or higher)
7) D604= 1N4148
8) IC601=UC3842B
9) C707 & C703= 1000uF 16V (must change, because of bad ESR value) secondary filter capacitor.

My screen symtoms are a little different on my L1975NW.


I am guessing the LED power indicator blinks green then becomes steady when the screen "turns on" (shows video). The problem is most likely a failing backlight power supply. That's why there is a 30 minute delay. Try to disable sleep mode and see whether that helps.

My dell monitor turns on for 2 seconds then goes black and the green light blinks orange


I assume that you already try this monitor on another PC to verify that the problem is in the monitor, in this case you need to open it up and inspect the fuse, transitors, solder connections on the power/inverter board, see failed Dell monitors here for guide: http://s807.photobucket.com/home/budm/allalbums

Blinking L.E.D. light on dell monitor


Try lowering the screen resolution to 1024x768 and see if it displays on the screen. You will need another monitor (possibly CRT as they do high resolutions) to do this.

The monitor would not turn on. Only the orange LED does.


1. Make sure the monitor cable is fully plugged into the computer. 2. If the new monitor works fine, The connection between the previous monitor and the PC was bad. Reconnect the original monitor to the PC and make sure that the connection is snug. Tighten down the video connectors until they are snug. Try again. good luck..
