LG FLATRON L1915S BLACK SCREEN AFTER REFRESH 1SEC

Hi guys I have a LG FLATRON L1915S Model L1915SN, the issue is when I power on the pc its shows a screen only for a sec and after that black screen (the light stays green and when I power off the desktop turns in orange as it is supposed to be). As checked it shows a screen for a second every refresh screen and thats all after that black screen, any idea what might be? and an estimated repair cost?

Old monitor , no PC stated, nor cable used < VGA>
test this old monitor on 2nd PC, if fails the monitor is bad.
it is 14 years old today, 2005 made
all this old are bad the toxic CCFL lamps go bad long ago.
best is the recycle center, it and buy only monitors and laptops
2010 or newer, or you get CCFL backlamps again.
the monitor this old has near zero street value, and repair costs are huge, nobody puts $1000 saddle on a $5 15 year old horse,
The CCFL panel can cost $100 and 1 to 2x that for labor
a used monitor is like $40 ,even walfart sells them called refurbs.

Testimonial: "Hi Larry thank you for your reply and your help, finally was the problem was on power supply (this model of LG had inside), I found and I replace it the cost of the PSU unit for my monitor was 20$ +10$ for installation , the colors on the monitor althought its age are exaclty the same as the first day that I bought it and the panel works perfectly if the issue was on the panel then I wouldn't repair it. I have also two other monitors (Samsung 23" and LG 23") 3 and 4 years old and I could tell you that the colors are not so great as the first time I bought them."

    the luck of the draw.
    that monitor must of sat broken for years
    so the CCFL tubes are not 20,000 hour old
    and still work. they vary rare find.
    most monitors this old crossed 20k hours many years ago and died.

    stick to 2010 and newer monitors that Are LED back lamp and they all have vastly longer life.
    spend cash on them and it has payback.

    I didnt measure how much hours the monitor worked , I thought if the damage is between 20-30 $ I will fix it , if it had more serious issue like broke panel I will not fix it , thats all now , they passed 5 month since I made it and it works perfect

SOURCE: hi everyone , ive got a LG Flatron monitor model

Check out for bad caps in the power supply first.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed 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 LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

MY MONITOR MODEL IS LG FLATRON T705SH I CANNOT ADJUST MY SCREEN RESOLUTION I WANT TO KNOW THE VALUES SUCH AS POSITION: SIZE: SHAPE: PLEASE HELP ME OUT SIR AS SOON AS POSSIBLE


Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

HI I have used LG Flatron L1915S computer monitor. When I plug it into my laptop, it blinks showing the laptop desktop for less than a second then goes black. Other monitors works fine when I plug them...


There is often a function monitor key on the laptop, located near the F7 key area, the icon looks like a monitor on|off and is typically in blue. this key is to be used in combination with the Fn key to enable, disable the external monitor or enable both monitors or just the laptop. Press the key combination until your laptop panel lights up while the monitor is plugged in. Now check your extenal monitor refresh rate and resolution slider settings by right clicking on your desktop go to properties / video settings. (please note monitor settings are under advanced). You should see two monitors in there now. use "identify" button so you know which one to work with. on the external monitor settings, decrease (slide left the slider all the way). If you can set the monitor refresh to 60Htz. Lastly take a flashlight and check if you can see a shadow of your screen on the external monitor, if you can that means the backlight is not working and likely needs the inverter replaced. Hope that helps ! Cheers

This is more likely an issue with you video card than your monitor, do all the monitors you have tested operate at the same resolution and refresh rate? It sounds like the LG monitor is running at a higher resolution and refresh rate which is causing addition load to be placed on your video card causing it to crash

When I open game the monitor become black and show: Analogique shortcut 53.6 Khz/85 hz


Your resolution or screen refresh rate sounds like it is too high.

Try dropping your resolution to 1024 x 768 and see if the issue persists.

If it does then perhaps your game is trying to force you into a higher resolution output and faster screen refresh rate than your graphics card or your screen can handle.

Assuming that the graphic output is fine when your not playing this game and just using windows?

I turn on my FLATRON L.1730 SF but after a few seconds it says POWER SAVING MODE and the monitor remains black.


Try selecting a different input from the monitor's menu, perhaps it is set for digital input while you feed it analog VGA signal, or vice versa.

After starting, my monitor displays "power saving mode".


Go into the menu and reset the monitor to factory defaults.

Cable advice...


There's an adapter cable required to go from the Mac's external monitor connector to a standard VGA plug. You can see what it looks like here at the Apple Store site. Once you have the adapter you can use a plain old monitor cable with VGA plugs at both ends to connect your Flatron.

When I press the power button LG displaying chars for 1 second


Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.

Unit is now working fine.
