Question about LG 23LS7D Television

Open Question

This LG set is being used as a video monitor. After being powered on for 5-10 min. the screen goes blank, leaving power indicator light green. When power button pressed off, then on video returns for another 5-10 min. then video is lost again. There is no change at all in the screen when power button is hit first time(green indicator changes to red 'standby' in lower right corner) and when pressed again video returns with no sign of problem...until it's gone again.

Replacement power supply is used?
You need to verify the DC output voltages of the power supply first and make sure this power supply has no bad caps with leaking/bulging tops. It goes into standby can also be that it detects fault some where in the set.

Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.

Lg flatron blank screen


t certainly seems like the monitor is not getting a signal. Did this happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,

Monitor only stays on for 30 sec. & then goes off then if I remove the power cord & re-power it up it comes on for another 30 sec. then goes back off


Howdy folks. There are only 3 things that can go wrong with a screen. Since you both are experiencing the same symptoms, let's ask the same question: When the screen goes blank, is the power button still green or is it orange? A green light indicates a good power supply and a bad screen. An orange light indicates a bad power supply but a good screen. I used to take them apart and try to fix them but they just aren't worth the trouble because they are so inexpensive nowadays.
Either way, I'm the bearer of bad news. It looks like you'll both be getting new screens. Please don't hold it against me when you rate my solution! ;-)

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

Screen goes blank


Screen going black would indicate a data flow problem- but then you would see a warning saying words to this affect or a back light/inverter problem. If by looking slightly sideways at the sreen you can see 'shadow images'[try a moving image to be syre] then you have a backlight /inverter problem If you see nothing at all ckecj the data cable pins- one or more may be bent
