Re: Power light is green but screen is black
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

mrmadgbull, How long will e17tg display the WIN-desktop before it goes to BLACK screen? Is it 1, 2 ...4, 5.....20 seconds? How old is unit? Does unit have internal ac to dc SMPS or external (lay on floor) SMPS? Did problem occur suddenly? What do you see on screen after "it" goes black and you shine a bright flashlight 1 inch from screen? Can you still see some icons being faintly displayed?? Is unit out of it's warranty period? If lcd panel is both black and blank, "switch-mode-power-supply" could be in full shutdown mode. If you see desktop, SMPS is in partial shutdown mode. You or electronics technician will need to evaluate and repair unit. Read my FIXYA profile for more options you may have open to you. Your monitor no different than any other "cold-cathode-fluorescent-lamp" backlit LCD monitor. There is a lot of DIY videos on YOUTUBE that deal with this type of monitor problem. Lots of tech types pick-up "black screen" lcd monitors at resale shops and refurbish them for less than $20 total cost, and they will work for another 2 -4 years. Do your research before making hasty decisions. If pocket is deep with disposable income, then just use e17tg as trade-in for new wide screen. Hope this was of some help. 12fixlouie
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
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
I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.
Have you checked your video source to ensure that this isn't a problem with your PC or whatever you're displaying on it? Try using a different display and see what happens. Try putting this LCD on a different PC and see what happens. If indeed it is this screen then it could be something as simple as a loose cable. Start simple and work from there.
The flash light test only works with lcd monitor as they have back lights.
Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
