I have a philips brilliance 200w6 monitor. probably 3 years old. about 6 months ago i turned it on to find the screen black, no picture. power led shows green, as normal. tried a new video cable, a different power point, no change. after some hours, maybe a day, the video returned spontaneously when the monitor was turned on again. four months later this happened again. last week it happened again. at that point i gave up and bought a new monitor. i miss the philips, though, it was a splendid monitor except for the regular break downs. i do not have any power saving or sleep mode features activated in my windows xp setup. the philips tech i spoke to suggested the monitor was going into its own built in sleep mode and not recovering appropriately. *i* say, why would the monitor go into its own built in sleep mode when it's turned off?
Nice anecdote, fixing things from far is not easy, a t.v.-technician right in front of the actual screen could tell more- but they don't come for free, alas. hope that people's idea about problem solving lead up to you fixing a problem yourself - hey this here is for free - to sort wxperts, one needs feedback! thx alot

sounds like the monitor is burning out or color is out of alignment could be result of burning out and no it's not worth repairing it. had one guy repair a montior a while back, could be looking at easy 200 to 400 bucks repair. not worth it. much cheaper to buy.
scle193, What happened that you needed to replace electrolytic capacitors? Why ??? Still no sign of power??? Did you pay attention to polarity when replacing the capacitors? Did you document you work with a digital camara to make sure that you could put it back together without having any leftover parts or unconnected cables. Have you measured the dc voltages at the output of the SMPS? Have you checked any and /or all onboard mounted FUSES?? What was the original complaint you had with this monitor? Have you tried to get a service manual or schematic from Philips? Get back to me with info
if you can. lmistyrel @aol.com bye for now. louie12fix
Do you get anything at all on the screen--like white writing at startup? Even if your video drivers have become corrupt, they are not used until Windows actually starts. It very well could be the flourescent backlight has gone bad. Can you adjust the brightness/contrast at all to see anything? If those controls do nothing for you, then you're looking to get a new monitor. Your monitor does have a sort of power supply for the backlight and that could be bad, but if you're not into taking it apart, then you are far better off buying a new monitor.
If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.
Did you check the sleep mode or power off mode? What
do you do to make it come back on? Sounds like it might be getting too
hot and/or going bad. Not sure how to diagnose this without seeing it
myself. That is the best that I can do. Your video card could be
going bad. Try another video card on that monitor. This will be the
only way to decide if it is the card or monitor. Try it on another machine and
see what it does.

I had mine for almost 3 years and last month ran into the same problem and i take good care of it. I turn it on it stays on for a 1-3 sec and goes black. can't figure out what it is
If you do not have high voltage training, messing in a CRT based monitor can hurt you due to the high voltage risk.
Detecting failed electrolytic caps is not hard. I've replaced the caps in my monitor a couple times (It's a 12 year old 21" CRT, that replaced a 10 year old 20" CRT 10 years ago), but you do need basic soldering skills.
An electronics tech could probably fix this for the cost of a hand full of caps, but remember, you will need to pay for service time (skills are costly), and that will probably run 75 to 100 dollars.
If you are concerned that someone may benefit from you lack of ability, then you can have the monitor diagnosed for $35.00 or so in most places, donate it to a charity that refurbishes computers for the needy, and let them fix it :), or just ride that bad boy until it dies (what I'm doing, I'm not replacing the caps a third time, I'm planing on getting a 24" widescreen LCD to replace my 21" CRT)
Peace.
