20 Most Recent LG FLATRON L1919S-SF 19 inch LCD Monitor Questions & Answers

Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.

Here are the service manuals: http://elektrotanya.com/?q=showresult&megnev=LG&megnev2=L194W&kategoria=monitor&kat2=all

After removing all the screws and the base, I use thin flat blade screw driver to crack open the case starting at the bottom egde and work your way around, just watch out for any cables attached to the front bezel. The monitor is not made to be easily open up.

Please read my guide so you will know what to look for inside the monitor.

Hi, Sounds like an issue of the video card not the monitor. Take to computer shop to verify. One thing you can try is drop the dpi down (refresh rate)a bit. Then try again. If that makes sense to you. Hope that helps.

It´s not safe to anchor it to the plastic back, monitors usually have a metal frame inside that support the weight of the monitor.

Sounds like it has a CRT and the EHT is collapsing. Maybe a dry joint around the timebase output transformer.

If you get half of the screen darker, remember that LCd monitor have 2 neon lamp at each extremity of the LCD, when one goes out you get this problem. it is possible to replace the LCD neon lamp, I did it many time, but you need to tear all the monitor appart and be carefull not to break any glass while doing so.

are you in dual screen mode on a laptop possibly? Check that the laptop is dual enabled so that it is either an extension or a duplication of your main screen. This is common mistake in setting up external monitor on laptop.
