SOURCE: Monitor goes black immediately after waking from

Common problem in this model is bad DC filter caps, that will be the first place to look.
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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My laptop sounds like it's running but the screen is black and the green power light and the blue wifi light is on. If I disconnect the battery it sounds light it's off but the green and blue...


If the screen is black but it's making all the right sounds that you'd normally get when the computer was working, then you can, in all likelihood, connect the NC8000 to an external monitor, do a cold start, and work off an external monitor for now. And you have also isolated the problem to be "up top" (the screen area)

If it just turns on but outputs nothing to the LCD or the external monitor, then it's probably trouble. I'd remove the memory and reseat them. If that doesn't make a difference, then you'll have isolated the problem to be "down below" (the motherboard, in all likelihood).

Hope that makes sense...

My flatron L1710S flat screen will not come out of power saving mode. When I turn on the monitor the power button/light is green for a few seconds, the screen indicated "power saving mode", then...


I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

PLEASE PLEASE CAN ANYONE SUGGEST ANYTHING give me

Acer AL1914 black screen, green light


it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.
