If you are going to DIY and have proper tools and know safety precaution then please read on:
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/home/budm/allalbums

Monitor goes black seconds after showing desktop


Does your monitor go black because it went to sleep, does it turn off? Do you have any lights on the monitor to indicate what it is doing?

Also I would boot into safe made by rebooting the computer & tapping F8 when the bios appears. You should be prompted with several options, one of which is "Safe Mode". Choose this & report how the monitor behaves.

When I turn my monitor on, the screen shows the desktop momentarily and then goes black. If I turn it off and on a couple more times, the desktop will stay on and function normally. Where is the likely...


Try the monitor on another computer, to check-out the monitor.

Does the POWER lamp on the monitor stay on when the monitor goes black? If so, then the monitor probably is OK.

Try a different monitor, to trouble-shoot the video-card.

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.

Backlight for display cuts out


Bad capacitors are a plague now, most likely cause of the black screen

simply remove the doomed and caps that have color leaking from the top. and replace with duplicate good caps from your local electronics store

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Laptop monitor goes black


If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time

I hope this helps.

RE:monitor goes black


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
