This is a sign of a backlight problem. First, check to see if you can increase the brightness by pressing the Fn and F6 keys at the same time. The F6 key is in the row above the row of numbers. The Fn key is on the lower left hand side of the keyboard between Ctrl and the key with the Windows symbol in a circle.
If the brightness won't change, then you would need to carefully disassemble the all-in-one to reach the LCD panel. You need to avoid breaking any of the small wires inside the unit. The panel has several parts held together by tape. The backlights are usually on the edges under the tape and a reflector. Often, they are molded into the frame; you need to use a Dremel or similar tool to free up the parts from the plastic frame. Make sure to note the way all the pieces fit together before taking things apart. Since this all-in-one has a 19" monitor, it probably has the backlights in pairs. Then remove the backlights and replace them with ones that match for length and diameter. http://lcdparts.net/ is one vendor that sells replacement backlights. This site also has installation details. There are other sites that show the steps involved as well.
This is significantly cheaper than trying to get a replacement LCD panel. A new LCD panel might cost more than half the price of a new all-in-one.
Good luck. I hope this helps.

Monitor has power. Will come on very briefly and the go to black screen. Can turn power off and back on and get the same above result.After a 2-3 hour period may come to life...may not.


It appears as if the monitor's back lighting is failing. To test the theory, take a bright flashlight and shine it on the lcd monitor screen when it goes black. If you can see the images that were on the screen before it went dark while shining the flashlight on the screen, then the back lighting is failing. Depending on the monitor, it could have florescent or L.E.D. back lighting, but it's usually more economical to simply replace the monitor with a new better performing monitor, than to attempt repairing the back lighting on the failing monitor.

Screen goes black after a few seconds.


when the screen goes black shine a flashlight on it. If you see a dim image the back light needs to be replaced. Otherwise check the inverter as that may be causing the problem as well.

The l226wtq goes black


Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

When I turn on my monitor I can see the Gateway letters come on the screen but then it just goes dark again. It comes on for a split second and then goes dark again.


joel_herrera, Yes, this is a very common symptom of a failing Switch-Mode-Power-Supply and/or Inverter circuit! Very common in 2-4 year old lcd/fpd's. How old is your's? Do you have warranty? Have you tried the Flashlight test? DO THIS! Reconnect lcd monitor to your fully booted PC with a known good WIN desktop screen. Then power "on" the HD2201 and tell me what happens and what you see or don't see after the screen goes BLACK! Shine a bright flashlight onto the screen at different angles and let me know the results. I'm louie12fix on fixya or lmistyrel @aol.com BYE

Monitor went black in seconds


oboy, One thing to try is the flashlight test. and get backto me with your findings. Tell me, does this lcd show a nice display only for 1-2 seconds and then a black screen when connected to a fully booted PC with Windows desktop displayed? Shine a bright flashlight 1-2 inches from panel and tell me if you see the WINDOWS START Button at lower left of screen even though screen is black! Get back to me if you can. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.
