Time to do a back up and replace he hard drive
Weird. Just got a notice my question had an 'answer'. This answer is clearly wrong as the problem had nothing to do with the computer, just the monitor. PLUS the question was from OVER SEVEN years ago, as can be seen from the two comments I added at around that time. However, apparently this terrible fixya system now identifies it as being from last year for some reason?!?!
PS. I did 'fix' the problem by finding the same model with a cracked screen for parts. Turned out there was something wrong with the main controller board and I swapped them, fixing the original monitor.
thanks dan, 99% of posters here never respond back and for sure never tell the cure, later.
way to go, you are a Jewel !
and for sure wise move mixing to dead monitors in to 1 good one is smart.
these old posts get awakened by spammers
99% caused, and is painful. to OPs.
good call
backlamps good
OSD dead.
logic board or psu inside dead.

woliphint, Did you try Dell to see if they can do a swapout? You send them your's +$40-$90 and they send you a refurbished same model with new CCF tubes+power supply/inverter? A lot of LCD/FPD displays have been subject to having their SMPS's fail due to poor quality electrolytic filter capacitors that can't endure the thermal stress inside the display. Nearly all brands are affected, not just Dell. See what you get when you search web for 'swollen caps' or 'bad caps in lcd's' or 'lcd repairs' or 'monitor re-capping' or similar type of search. You should always state age or approximate usage hours of the monitor when posting to fixya. We don't know when a 2405FPW was produced and sold. As long as you haven't cracked, shattered, or abused the LCD panel you should be able to get it swapped and or repaired. I'm louie12fix on fixya or [email protected]
Bye for now.

Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.

Hello,
I would check the capacitors on the power supply board first. This is the most common problem with LCD monitor after a year or two of service. Open the back and look for bulging capacitors, replace any that you find and you should be back going again. Check our web site at: www.ccl-la.com/capacitors.htm for pictures and information about this common problem. If you need to get parts or have over questions let us know at [email protected].
I hope this helps, if so please rate our solution.

Well, no one here bothered to help and I couldn't find my exact problem elsewhere. Guess I needed to offer a 'reward' to get help. Regardless, it was suggested elsewhere that I check the capacitors on the power board before messing with CCFL backlights (that I thought it might be). Sure enough a few 220uF and a couple 1000uF 25V caps were slightly bulged on the end(s). I went ahead and replaced them and it's starting right up again with no warm up needed. I'm adding this comment in case someone else come looking with the same problem. Good luck.
Ooops. FFS, I have posted another problem with a Viewsonic 22". Unfortunately I added a comment on fixing the Viewsonic here under my Dell 24" problem. Don't see anyway to delete the comment so I'm just adding this as a correction. The Dell 24" still has no solution and it's caps don't appear swollen.
The Viewsonic's problem was that the backlight wasn't coming on at first and needed to power it on and off multiple times before it finally lit up.
how did 2011 posts land in 2017 OP post.
crazy fixha, wild thing
the correct answers on any LCD 2005 display is CCLF are bad
gee all are now. why expect them to be good.
if the OP used a flashlight when dead
and saw data now, then the CCFL are dead.
the fail all these ways. posted here by me 100 times.
1: dead CCFL ,
2: dim.
3: strobing (blinks)
4: totally random intermittent.
5: yellow screen for white.
now ill read your service manual to you
just one line, facts matter here. for sure .
6 CCFLs U-type backlight.
if the tubes are wired in series
if one goes deal all 6 go dead, just like cheap Christmas tree lights, (chevy chase xmas vacation movie, seen)
sure it can be tubes or inverter
and caps.
sure it can.
to prove that takes tools,
you can in fact buy a CCFL lamp tester off fleabay cheap, $10?
or replaced inverters, or caps.
on Monitors is this large PSU board.
that has huge CCLF HV transformers
and CCFL jacks huge.
this board can be replaced too, found used
and good on fleabay.
sure caps can bulge crack or leak or just dry out and be useless, we test them with an ESR CAP meter, all good shops have meters.
we even have scope in the shop and with HV probe that we can use to find true cause.
The voltages can be as high as 600v
so make sure power cable pulled,
let set 1 hour or use cap discharge probes
ask we have all that and more in the shop.
see what CCFL port (HV) look like here.
