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.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

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"
