Question about Dell E176FP 17" LCD Monitor

1 Answer

Picture ok for a few minutes then go blank

Number is CN-OGC811-72872-66Q-078M. When I turn on the monitor, the image appears for about 10-20 seconds and then goes blank. If I turn it off and turn it on again, it will do the same thing; image works for few seconds and then goes blank. Another post said to replace the graphics card, but I want to make sure because we tried this with someone else's PC and the same thing was happening. Any help would be helpful. Mitsugo

It is your monitor inside problem, you need to know follow issue:
1) inverter board some where the component got less connection
like MOSFET drive or capacitor swelling need to resoldering or change.
2) the back light lamps worn that most cause this symptom, need check or adjust inverter driver to match them work well
3) DC power supply filter capacitor swelling should be this problem, check and fix it.
hope help you something do well, please feedback any question any time,

My samsung syncmaster 920nw picuture goes blank after a period of a couple of minutes. If I turn the power off and then back on the picture re-appears but goes off again. It is not he pc since it works...


If you get a flashing screen which show your screen for few minutes and then goes blank it may be an issue with the Monitor.

Try to restart the computer and go to BIOS setup screen. If you experience the same issue in BIOS then the monitor needs a repair or replacement for sure.

Monitor starts, about three minutes no picture but


Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after few seconds, 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 within your vicinity or any service center 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.

Asus Monitor boes blank and comes back after power recycle


1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

Monitor comes on, then goes back off, rinse, repeat.


Well here is a test you can do. When the monitor goes black, take a flash light and hold at it a angle towards the monitor, if you can still faintly see the image then you have a blacklight/inverter issue. Another common issue with this is the capacitors on the inside. They will also cause this. If you dont see an image then the inverter will need replacing. As the steps for replacing all of this are quite long, ill post a few helpful tuts :).

For replacing the backlight:

For checking/replacing bad capacitors:

I know these arent your monitor but its generally the same idea with all of them. If this doesnt work it will be a inverter issue and if it comes to that just let me know and ill be glad to help :D
