    same problem. LED flickers 3 times and I can hear a faint buzzing from the speaker. I've opened it up, the inverter board looks free of any scaring from burnt or damaged components.

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.

HP LP3065 monitor turns off and won't turn back on; is this a Windows problem


It doesnt sound like a windows problem. A simple test for this is to unplug the vga or hdmi cable from the monitor then turn it on if it has power it should say no signal. Also try either another power cable to the monitor or change the fuse. Hope this helps.

My hp w1907 monitor has suddenly stopped working!!as soon as i turn on the tower it just displays"monitor is going to sleep"PLEASE HELP!!!


I love this one. I've actually done this many times before and have been successful.

1. Turn the computer off and unplug the power cord from the back of the tower.

2. Press and hold the power button for about 3 seconds while the computer is unplugged (this drains the remaining power from the capacitors on the motherboard).

3. Plug the computer back in and turn it on.

If that does not work, follow steps 1 and 2 again, but this time:

3. Open the computer while it is unplugged and unplug the power supply from the motherboard then hold down the power button again for 3 seconds. (You may also want to take the RAM out and put in back in)

4. Plug everything back in and turn the computer on.

Hi I have an HP LCD Monitor and i am receiving a message that says DVI No Input VGA No Input Monitor Going to Sleep and it shuts off.. I have tried unplugging all the cords and replugging them in and this...


caligrl2007, Sorry to hear you are having problem with your monitor. When very strange things start to happen with an LCD monitor, the first place I would look would be the "switch-mode-power-supply" inside of the unit. If unit does same thing when connected to KNOWN GOOD pc, then a technician will need to investigate the SMPS. 12fixlouie

Hp flat panel monitor comes on shows logon and then blank screen


Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

Monitor goes blank , power light goes off.


Click start, then then control panel and click on the power management icon. When you see the screen, look at the power management "scheme" and pick the appropriate setting. I assume that what you are experiencing is what's known as "Power management" . In order to achieve an "Energy Star" rating, the computer must shut off various components to conserve power. If you don't want to have your monitor shut down, select never from the options in the Power Management screen. Thanks for using Fixya.com

Flatron l1717s blank screen


Common cause of this is the VGA or DVI connectors not screwed on tight on either the back of the PC or the back of the monitor.

Also try removing power by unplugging for 30 seconds, sometimes that will reset things.
