Lg w2343t monitor

try monitor on a different working desktop to see if it works, both on the external and internal video card ports. If screen menu buttons fails to respond, fault is either on menu buttons or you may have a burned out lcd screen, try a different monitor on your desktop pc to check its functionality. Monitor probably needs replacement.( It might not be burned out for you mentioned "no signal" error message appeared on screen, have the screen menu buttons checked)

Screen just went black, power light on; is there any easy fix or should I trash monitor?

Try disconnecting the video source; most monitors will inform you of the missing signal by putting a warning box on the screen if they are functional. Before ditching it, I would try connecting the monitor to another computer or borrowing a monitor to make sure your internal video source is working.

Hi.i have a dell e521 with a e197 fp monitor. when i turn the system on the monitor stays in stand-by mode. so i have a black screen,is it broken?

not really.. theres a possibility that the monitor is just on standby mode. try to disconnect the power cable of the monitor, then hold the power button of the monitor to drain its flea power. put the power cable back then try it again.

if its going to do the same thing, check the connection of the monitor at the back of the computer. see if its seated properly.

try restarting the computer..

try draining the flea power on the computer as well, possible that the computer is in standby or hibernate mode..

My 15" LCD monitor TTX went to sleep mode and never return back

mike_garzan, Your monitor will need some work done on it!! Do you know the "flashlight trick" that every owner of an LCD monitor with "cold cathode-fluorescent-lamps" should know how to do when the BLACK screen of death makes it presence known? Do this test first! It is a very easy test to do. 1. With a KNOWN GOOD pc fully booted to the WIN-desktop showing on a GOOD Monitor have a friend tap the CTRL key on the keyboard every 30 seconds or move the mouse to ensure that the pc won't go into sleep mode. 2. Power off the good monitor and disconnect it from the pc. Now reconnect the TTX9151 to the pc and wall outlet power. 3. Then and only then turn on the monitor and make note of what happens. Did you see or not see the WIN-desktop appear?
4. Now for the flashlight test. Even though the LCD panel appears BLACK, shine a bright flashlight about 1" from the screen's lower left corner and make note if you can see the Windows START icon even though the screen appears to be BLACK. 5. Turn off TTX9151 or yank the plug from wall outlet, and disconnect from pc. TEST IS DONE. Reconnect good monitor to pc to get back online. The test was to evaluate the current status of the "switch-mode-power-supply" and the CCFL inverter circuit DC source. If you could SEE something on the BLACK screen then you know that half of the SMPS is working and sourcing voltage (+5 or +3.3v) to power the vga/lcd interface board! It also means that the SMPS is not in FULL SHUTDOWN mode and only has a problem sourcing voltage(+12v to +18v) to the CCFL inverter circuit which generates 800v to 1200v ac to light-up the CCFL's that are hung across the rear of your LCD panel to produce the WHITE LIGHT needed to see what is on the screen. Now, if you didn't see the WIN-desktop, then the SMPS is probably in complete SHUTDOWN mode trying to save itself from a CATASTROPHIC, NONRECOVERABLE failure! (eg. smoke and fire) Put the TTX9151 in a safe place and get back to me with results of the TEST. lmistyrel and on or do a comment to your original post above on fixya and I'll give you advice as to what you need to do about getting it repaired or other actions/options you as a consumer/user of LCD displays have open to you. Bye for now. 12fixlouie

No power to Dell E173FPc monitor; power light doesn't come on

It sounds like you are not getting any power. I would try another power cord to see if it makes a difference.

The backlight power supply in the H950 series suffers from a manufacturing defect. Hansol might replace the unit even if it's not covered by warranty anymore. Contact them.

Otherwise (and if you have electronics skills), replace the electrolytic caps in the monitor's power supply. Take proper high voltage precautions!
  • Disconnect mains
  • Wait at least one day for caps to discharge a bit
  • Remove monitor stand (four screws)
  • Put the monitor face-down on the table, plugs facing to you
  • Remove back cover (snap-in, difficult to open without minor damage) - be cautious: front buttons are connected using a rather short cable, do NOT try to remove front cover
  • Remove EMV casing screws (four screws) and ground wire
  • Disconnect CCFL tubes (four connectors), noting connector orientation
  • Disconnect front buttons pcb
  • Lift EMV casing side facing to you
  • Disconnect power supply board (left) from signal board
  • Unscrew/remove power supply board - caution: C12 is likely to store mains voltage even after days!
  • Replace caps (C34 and C66 are likely failure candidates for IPHS19-S rev1.2 boards; you might also replace C31, C32, and C35 while you are at it) - higher voltage and temperature rating are okay, capacity has to match
  • Assemble everything again

Green light blinking screen blank

Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.
