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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

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).

My AOC screen goes black after about a few seconds after booting.


Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

I have a Dell SE198WFP Flat Panel Monitor, screen goes black?


The LCd panel may be damaged and will cause this problem.

Another thing is overheating of the GPU.

The LCD signal receiver can be goign on you.

The is also the possibility of a faulty inverter.

Only thing to do is service or replace. Test the unit on another computer, if you don't get the issue there then you know its a problem with the PC.

The monitor goes black while on


Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...

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

My screen goes black after a few seconds


Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.

SCREEN GOES BLACK AFTER A FEW SECONDS AFTER TURNING MONITOR ON.


More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.

If this helps, please rate my solution. Have a great day.

Screen goes blank after a few seconds


Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.
