This problem is a failing of the backlight circuits. the lamp is either failing or the power circuit is failing, causing the lamp to dim down it power output. Return to dealer for service. Hope this helps you.

My moniter screen go's dark with a bright horizontal white line in center ..it flickers


the driver board is bad in the monitor. Has it been in a place that is super hot like in a car? If the verticle driver chip disconnects from the matrix driver array, it will all squish into a single line in the middle of the screen like you are describing.. might try opening and blowing where the driver board connects to the LCD matrix (bunch of connectors on a plastic flat cable/bus connecting to the end of the LCD panel.. heating them could allow them to reconnect.. Its worth a try, right? It has worked for me about 60% time.

I have a Envision EN-7100e monitor. Downloaded


catamount309, This is only a guess, but unit may have internal "switch-mode-power-supply"/"CCFL inverter" board problem. When screen goes BLACK, is it also BLANK? If you can see WIN-desktop with aid of bright flashlight 1 inch from screen, then SMPS is in partial shutdown mode. If you see nothing, then SMPS is in full shutdown. In either case, Technician will need to repair the SMPS/CCFL inverter board. If KNOWN GOOD monitor works with PC, then you know 7100e is bad. Do you know and understand how the new energy efficient screw-in curlie-Q light bulbs work? If the "electronic ballast circuit" not working, then it can't light-up the CCFL tubes on the reverse side of LCD panel then you see black. Do more reading in my fixya profile for more options open to you. Do your research first!! Hey, reading is free!!!
Will you fix or trade for new? 12fixlouie

If the monitor was dropped, most likely you damaged the internal components that provide the picture, whether LCD or CRT. Try connecting it to another computer. If this doesn't work, check the monitor's display settings or operating system display settings for contrast or brightness. NEVER open up the monitor, because there is a high voltage capacitor that stores voltage even when the monitor is off and could kill you if it discharges.
