Screen fading to black

Probably the power supply is failing

Connect your laptop to an external monitor and switch to monitor. If the external monitor shows the desktop, then the complaint is in the lcd/led display unit means the screen. Replace the screen. If the external monitor also shows the complaint, then it is normally due the mch(media controller hub) . It comes as separate card unit in some models and onboard for some other models.Only an experienced technician can solve that issue. In some rare cases it is due to a corrupted BIOS. Reply if this helped you.

That sounds like a very typical issue with "Viewsonic " monitors. The issue is with the screen.

Try a different video card or disconnect the one you have in your PC and use the VGA monitor connection on the motherboard. If it works your video card is gone.

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.

Will you fix or trade for new? 12fixlouie

Look inside for bad caps with bulgng tops, worst case will be shorted out transistors in the backlight inverter circuits or bad lamps. Check to see if you do have he 12vdc for the inveter circuits. See example of failed monitors with bad caps here: http://s807.photobucket.com/home/budm/allalbums

Open up the set and look for bad caps, see saome examples of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

Hello

My first guess is that the screen circuitry has gone bad - although fixable. Use an external monitor to verify this. If the external monitor is fine then the screen circuitry is bad, if the external screen shows the same problem then the video chip or associated circuitry has gone bad. My company fixes these all the time.

SOUNDS LIKE BAD HARDRIVE after the logo screen and fade screen Then what happens ? does windows begin to load.

We had the same problem with the 17" we bought in Aug. Sent it back for repair. Acer sent it back without fixing the problem. Started doing it again in Nov. This time I called a supervisor and they sent me a new monitor. Well yesterday it started doing the same thing. You can fix it temp buy unplugging it and holding down the on-off switch for 30 seconds. Please let me know if you have a better fix.
