Question about LG Flatron L1715S 17" LCD Monitor

No picture for a while, green flashing light

As per the title, when I sitch my monitor or my pc on, sometimes I just get a green flashing light on my monitor with no picture.. It can take up to 15 mins for the flatron splash screen to appear. I orginally thought it may be a cooling off period after having it switched on for a while, but I had the monitor turned off overnight whilst I was downloading, and when I switched it on, I had to wait 10 mins before I got a picture. I am running WinXP Pro, and have all power management features turned off in both Windows and BIOS.. If someone could give me a clue as to what's happening, it'd be appreciated... Thanks Wizborg.

    My Dad helped me buy my computer when I went off to school and he has all the info (at least I hope he still does) any chance of the monitor itself coming with a warrenty instead of the whole computer package?

That is a defect with those should get the returned to the store...if you can't then you may have to do some soldering is a power issue with the monitor will need to find the replacement capacitor inside..but still the best advice is to return the product

Jus like to say i just did the folding the screen up thing while the pc was booted and the screen appeared... so give it ago .

The problem with older builds of this monitor is in the power card. It suffers from dry solder joints and the capacitors can fail. No picture for a while, green flashing light - Image of how to repair here:

    thank you for this - I replaced ( bulging ) c202 with 1000uF 35V ( from an old printer ) an now I have saved £100 ! hooray


The L1715 screens have a issue with the internal powersupply. You get it fixed on the warranty

Same is happening with my L1710S. I believe it could be an internal power issue. Plugging out the video cable does nothing, the green light flashes. Turning off the computer, same thing. But when the computer is off, unplug the power, wait for the light to go out and plug it in again - start up the computer and hey display! I'd get it attended to asap, 3 year warranty :)

The exact same is happening to my flatron L1715S monitor, and its only been out of the packaging just over a week now. Initially I was using the workaround of turning it on then back on and it would show the flatron logo and work but now that doesn't work any more and no matter how long its left on for, or how many times its turned on & off it just gives the same flashing green light with no display. You will never guess what, earlier after reading this post, I somehow managed to make it work properly and it displays the flatron logo and works properly each and every time its turned on. I done this by booting the pc, then while the monitor is ON and flashing green I slowly moved it down into the fully folded position, then miraculously windows was displayed once again at this stage and I slowly moved it back to an upright position. But if this method works for you it still doesn't mean you shouldn't get it seen to if its under warranty.

Monitor Not Showing A Picture. Light flashes Yellow and Green.

use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

Monitor picture fades out.

I thought my problem was originally monitor related. However since I posted, the picture disappeared altogether, and my PC wouldn't even start to bootup. Fearing my mobo may have died I removed the hardware components, cleaned then re-assembled them. After all that, it turned out that my graphics card has a tendency to become slightly unseated. Once I was aware of this problem booting up resumed normally. It seems that the problem of the fading monitor picture seems to still occur, but soon after I use the machine after 'hibernation' state, and even then it doesn't always occur if I do use hibernation. I haven't used hibernation for a little while and so far the problem has not returned

Power of the Monitor keeps going out.

You need to look inside your pc and check and see if the video card is plugged in tight. Sometimes if it is loose, and it isnt connected, and causes the monitor to not show any picture, but still has power.

Blank Screen..Will not power off

The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
