Re: screen

Could also be the bulb... some LCD Desktop bulbs can be replaced with as little as $10.00 (us) and a little bit of soldering

Re: screen

Sound like you have a bad power inverter inside the monitor. These can usually be replaced on laptop screens, but I have never seen the parts to do it on a desktop LCD screen ( eBay might be a good shot), but your best bet would be to send it to the manufacturer for repair.

Good Luck,

How do I turn off the Samsung sync-master p2050 monitor?

If it doesn't turn off by holding the power button down for 10 seconds, then it cannot be turned off by the power button alone, like most modern lcd monitors. Most modern monitors goes into standby mode. To completely cut power, you must unplug the power cable.
I've enclosed a link to the install manual for reference.

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 goes wrong:
Post back what you see inside so we can guide you further.

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Black screen

• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.

That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.

Replace your battery.

If it was the power supply, the light would change to amber (orange) and then turn green again when it comes back on. Look closely at the screen when the it looks to turn off. See if you can still see an image. It may be hard to see, but when the backlights go bad or fail, the actual lcd screen itself still functions and you can see a very faint image. Maybe moving the mouse in circles might help you to be ablt to see. If you cant see anything at all, then it may be a bad board inside the unit.
Just a thought....

Screen goes blank after 2 seconds

Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.

If it physicaly powers OFF, then you probably have a power issue.

Monitor screen goes out (black) 2 seconds after turning on

Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page. Places like yours have no place on the internet and I'm going to find out what I can do to report you.

Thank's for nothing
