Tip & How-To about Computers & Internet

LCD monitor displays background fine for a second then goes black

If your LCD monitor displays your desktop fine as it boots up and then goes blank after a few seconds, but you can still faintly see your desktop then this may seem like a brightness issue but it's not. The picture displays very faintly, this is because the LCD backlighting isn't working properly. Which in turn is either because (most likely in cases like this) the inverter circuit has failed or the cold cathode tube has blown. If you're new to the electronics business and are not sure how to solder and connect circuits then this is the job for a qualified repair technician. So i suggest you head on down to your local PC store and have a technician take a look.

If you want to try it youself go here to order some spares.
If the monitor switches off and you can't see your desktop faintly then this may just be a power saving issue. Yo fix this check out my other tip here.

If your monitor is less than a year old then I suggest you take it back to where you bought it and have them send it in for repairs or swop it out with a new one. LCD monitors usually have at least a 1 year warranty sometimes it can even be up to 3 years if you register yours when you purchase it or if it's a really expensive screen.

If the monitor is a good 4-5 years old then it may not be worth fixing or may be too expensive. I suggest you invest in a newer widescreen option. LCD monitors have drastically come down in price over the years and you can easily get a wopping 23" for as little as $180.

Dual Monitors. #1 works fine. Plug inb #2 and #1 goes to sceeen saver and #2 stays blank.


Both monitors must be plugged in when the computer is started for the second monitor to be detected, and you must configure the second monitor once the computer has started
In windows XP: control panel -> display -> settings tab -> select second display -> check "extend my windows desktop onto this monitor" -> click apply
In windows vista/7: control panel -> adjust screen resolution -> select second display and then under "multiple displays" select "Extend desktop to this display"

My monitor will not stay on and goes black after a few seconds when I reboot it. I'll turn the monitor on and it stays on only for a few seconds but I can see all of my programs for those few seconds.


maryfoldesi1, Your monitor power supply is going into shutdown mode becauce it has detected a fault within the unit. A technician will need to evaluate it. Before doing anything visit YOUTUBE to view vid clips of "LCD monitor disassembly" and "LCD monitor repair" Also read more of my responses to other owners that have BLACK SCREEN problems and find out all your options you have open to you. You did not tell us if you can still see the Win-desktop AFTER it goes BLACK. Is it also BLANK or can you still see a faint image on lcd panel if holding a bright flashlight 1 inch from screen? lmistyrel on aim.com 12fixlouie on fixya

The panel initially displays and then goes blank


johnerm, Good going John! At least YOU tried doing a swapout to another KNOWN GOOD pc to prove out that the E153FP is indeed the culprit!!! Now for the hard part. Do you have a bright flashlight? Reconnect E153FP to pc with WIN-desktop as the displayed image. then and only then turn on E153FP and note the time it takes to GO TO BLACK SCREEN. Is it 1, 2, --5,---20 seconds???? Now point at different angels about 1 inch from screen a bright flashlight to an area that "should" have a desktop "icon" showing. LOOK very closely!! If you SEE a very faint image of the desktop the units "switch-mode-power-supply" is in PARTIAL SHUTDOWN mode. (still has +5v or +3.3v to supply vga/lcd interface board) If you SEE NOTHING, then SMPS is in FULL SHUTDOWN mode. Get back to me, 12fixlouie with your SMPS flashlight evaluation and pay a visit to YOUTUBE fyi search and view video clips of "LCD monitor disassembly" and "LCD monitor repair" to see if DIY interests you! Also try www.ccl-la.com/badcaps.htm run by another tech on fixya nickname "buddymc" fyi. If this was of some help, rate this response on fixya. 12fixlouie aka louie12fix or lmistyrel @ aim.com

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
