Re: Dell Monitor Not Working
Well if the status of the LEd on the monitor is amber(orange) & the system is running on a on board video card & not a Add-on video card... it is a possibility the the integrated video card ot the mother board might have gone bad... either contact a local tech or the tech support for the computer...
also unplug the monitor cable from the system tower & then if you see that there are the bars moving which say monitor self test on... means tht the problem is with the video card or the mother board...
since the system is running on a integrated video card...

Do you see an orange light on the monitor anywhere? Usually the light
turns green when the monitor comes on, but its orange when in "standby"
mode. If your monitor is plugged in and you get an orange light, that
usually means that your video card has gone out on your computer. When
your video card goes out, the monitor doesn't receive a signal from your
computer, so it
doesn't know it is suppose to turn on. So if this is the case, you need
to replace the video card on your computer
If your monitor
doesn't turn on whatsoever, and everything is plugged in correctly, then
you need to get a new monitor or send this one back to the manufacturer
for a defective replacement.

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 Post back what you see inside so we can guide you further.
Take off the monitor and hook up another known working monitor to the computer and turn the computer and monitor on. If the computer turns on with video then you know the original monitor is bad and would need to be replaced.
Try booting the pc in safe mode (press f8 at startup). It may be possible that the pc is trying to send too high a resolution to the monitor...unlikely though. The symptom you describe usually indicates that the power board or the inverter board in the monitor are defective. If it does the same thing in safe mode, you have 2 options.
1. Replace the power board and inverter board (do the inverter board first.......it's the cheaper one (10-20 dollars). 2. Send the monitor back to the seller for a refund, or get a new monitor.
Sorry I couldn't give you more positive feedback. Hope this helps.
Hi, First, verify the monitor is functional. Monitor STFC (Self Test Feature Check) Turn off the monitor Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation Unplug the monitor video cable from the back of the computer Turn on the monitor The floating dialog box should appear on screen against a black background. If the issue appears during the STFC, the monitor is defective. What are the results please?
Please disconnect the Monitor Data cable from Computer. If you see Dell Colored bars, it means, monitor is working fine, If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.
Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...
Blinking Green shows that computer is in sleep mode......
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.
This problem of dell e151fp lcd monitor, you just need to resolder the inverter section (bad points or dry joint) and also check the capacitor value with ESR meter. It will solve your problems.
