Did yo verify that the new lamp solder connections are good, were the old lamps have any sign of wear such as blackened ends, or glow with pinkish color?

How are the caps and DC voltage readings on the caps?
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro lamp that provides the back lighting for the screen.

Dell monitor screen suddenly went white. Can it be fixed?


I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

Dell E228WFP monitor cutting off, goes black


sysjrm, You need to visit YOUTUBE for video clips of "lcd monitor repair" to see if DIY project is what you can handle!!! After you "learn by seeing" some printed circuit "switch-mode-power-supply/inverter boards" having their "aluminum-can" electrolytic filter capacitors replaced and/or "thermally-intermittant" fractured solder-joints "resoldered" then you will be able to make decision on what to do about attempting a repair to your E228WFP! Note!!!! Make certain that your pc is not the cause of your BLACK SCREEN or BLACKnBLANK SCREEN problem/symptom by connecting a "known-good" monitor to your pc first!!! Please read the higher numbered(32 and up) pages in my fixya profile for more information on how to do the simple "flashlight test" for evaluating the state of shutdown that the switch-mode-supply may be in. Also read and follow the links you find in the profiles of "budmrtn" and "buddymc" that are very good ccfl back-lit lcd monitor technicians here on fixya. After you do your web research, remember to come back to this posting and do a comment and rating of this response if you feel that it has steered you in the right direction. Good luck with the repair. 12fixlouie

Monitor turns on and screen comes up for about 1 second and then turns black. Green power light stays on and green


This will be a fault with the inverter section that powers the ccfl lights usually a transistor or an i.c replaced will cure the problem

After 1 year, the monitor DELL E228WFP started to turn black


ainamat, Did you do the FLASHLIGHT TEST to evaluate the status of the "switch-mode-power-supply"??? Every owner of a lcd display with "cold-cathode-fluorescent-lamps" backlighting should know how to perform AND interpret the results!!!! It's a very easy test to do! FYI Your monitor has a backlighting sysem very similar to the NEW curlie-Q CFL energy-saving screw-in light bulbs!! They have an ELECTRONIC BALLAST (converter) circuit (ac to ac) to light them. Monitors have a INVERTER circuit (dc to ac) ballast circuit that generates 600-1100vac to light your CCFL's. If the SMPS detects a FAULT with itself or a circuit that it is supplying power to, It will go into SHUTDOWN mode to try and save the unit from a catastrophic, nonrecoverable failure. e.g. worst case sparks,smoke,fire!! Anna, you should READ and follow the threads in my other responses if you can get to my FIXYA profile pages under 12fixlouie, aka louie12fix and read what I have already written about the BLACK SCREEN of DEATH and YOUR options. If after doing some surfing of the net, you determine that this response has steered you to a solution to your BSOD problem, please rate this response on fixya. Good luck in your quest. 12fixlouie
