My Lg monitor L1950B is not displaying anything on the screen but power is on..Help please


of the power lamp glows. and the OSD is dead.
then its dead.
check AC power, carefully, use a desk lamp to be 100% sure
there is power. if power lamp is off.
if OSD works
then plug in Display to another PC or lap top.
the Lap has an external monitor key, that must be pressed.
if the screen good, the so be it, bad pc.
if screen is dead, so it is.

When I push the power button to power the lap top up the light display that says outlet power changes from green to amber and the laptop will not power up.


try removing the battery and just use plug power only if it boots normally then change the battery and the change the power supply unit as well I would just start with the power supply unit first then see if the battery charges up if not the battery is bad replace it. Now if the computer will not start with the battery removed then you have a power supply issue.
Change and replace it. Hope this helps. Also when computer lap top get hot they will shut down to protect the computer wait and let it cool down then try to restart your computer. If this does work and the lap top restarts normally get a fan cooler that is USB powered and the lap top sits on top of it. Also make sure the fan is running and is not stopped. Clean and dust it out once in awhile. I hope this assists you with your problem. John

All my saved pictures have been deleted and the screen continually goes blank


Greetings and thanks for the question, there are various reasons why this happens. Without having your computer here to see what is going on is anybody s guess on how to repair it. If I may offer some suggestions. Since I also do not know what operating system you are using I will assume it is Win 7.
I would personally go to control panel and check my power options to make sure I do not have the settings set you close display or sleep mode or anything set to soon to close your machine down. Often times people have these set to go off there are defaulted usually to save battery usage and your lap top from getting to hot and shutting it down. The thermal switch may be activating sooner than normal. What some folks do is purchase one of those underneath fan coolers to keep their lap tops from getting to hot and constantly shutting down.
This can be the case have this checked out at least set the lap top for more time before closing down or turning the monitor off. Let us hope it is not more serious than appears. Like a lamp in the monitor going out. If it is new the lap top I would not worry about that issue because it is intermittent. Which leads me to believe it is a thermal or a shut down issue. Get the cooler fan for your lap top I recommend anyone that reads this post to also do this as well. Clean your lap top blow them out it is critical to do this to keep dust away and keep it clean.
Now there is recovery software which is free to download Click Here to check this out to retrieve lost files. Also important to get those precious memories separate off your computer and on to separate CD or DVD or storage USB stick so that when this type of thing happens you have not lost your precious memories. I hope this helps you. John
