These monitors are switched by a signal from your computer. When this signal is present, the monitor turns on, when you shut your computer down, the monitor turns off. In the meantime it remains in "stand by" mode. The main moitor switch should turn if off alltogether. If it doesn't, the swich can be replaced, but cecause these are "momentary" switches it's not an easy thing to do.It won't matter a lot if you don't replace it.
pdshapiro, Learn flashlight test in my fixya profile to determine current state of shutdown of units "switch-mode-power-supply"... Then do more reading and visit some of the web links mentioned in my many responses to other owners of Black or Blank n Black screen monitors. You will find out all you need to know and all options if you read my older (late 09 posts) responses to other owners of same or similar sympton ccfl back-lit lcd monitors. JUST DO SOME READING FIRST. Then come back to this post and give it a rating if it steered you in the right direction. Bye for now. 12fixlouie
stlmeuzyk, Internal "switch-mode-power-supply"/"ccfl-inverter-supply" will probably need to be refurbished (repaired). Use Dell warranty first if valid option! Try monitor on different pc or verify your pc is working properly with old, but known-good monitor. If your E228WFP unit is still not working then you or qualified electronics technician will need to tear-down monitor to evaluate and repair the ac to dc power supply printed circuit board. Before you do anything read my fixya profile to learn flashlight test that every ccfl back-lit lcd monitor owner should know how to do and interpret the results of test. The basic design and operation of your E228WFP isn't any different than any other brand!!! Read the older solutions in my profile and follow the links you find there. Then do additional comment if need more info. Good luck with the repair. 12fixlouie
I have worked a great deal with the Dell E177fpv boards and when it is blinking power switch then it's bad. Most the time it's the C204,and C203 compositors that are bad (100uF 10v), and 70% of the time the C159,C154 ( 470 uF 25V are bad as well. now i have replaced them many of time and it had came back to life. i have also found other caps bad on it as well. i know you can order a new board for $39.00 and here is the link. http://www.lcdrepair.us/e177fpv_inverter-power.html Good luck!
You'll need to troubleshoot a little.
SOmething may be broken, but you'll need to find out what.
1: Try the monitor on another computer, see wether it will work on that one. If it doesn't, the monitor's broken and you're probably going to need a new one.
2: If the monitor does work, put it back, but now use another cable to connect it to the PC. If that fixes it, your cable was broken.
3: If not, you could try to switch the graphics card in the PC with another one. Do not attempt that, however, unless you know what you're doing. If you don't, get someone you know to do it for you, or take it to a computer shop.
If the PC will boot with another graphics card, the old one is broken.
4: If not, it may be your motherboard that's broken. Repeat step 3 with it.
These steps should fix your problem. If not, please post back here.
To me, that's an XP driver issue. If the screen turns on at all, then goes dark during XP boot, that's nearly a ringer for drivers.
Out of range on the Hz? Tried booting in safe mode to see if it loads with standard win drivers? That might work. Reset the monitor to default/standard settings and try safe mode is what I would do. Ramp up the resolution/refresh rate from there.
It sounds as if you have a resolution set that the display does not support.
Restart your machine in safe/VGA mode by holding down F8 while the machine boots. Once in safe mode, set the resolution (Right click--> properties--> Settings--> Screen Resolution) to one that your display supports.
