Hello Steve,

The most common problem with the L194WT monitors is a failure of the power supply board. There are parts called capacitors that fail and can cause the issue you have. Sometimes the power light will just flash, sometimes it takes several minutes to display a picture or even a wavy picture, all of these issues indicate a failing power supply board. These boards can be repaired if you can do a little soldering. The L194WT uses the same power board as the L196WTQ and we have a step by step repair guide with dis-assembly instructions available at http://www.ccl-la.com/blog/index.php/lg-l196wtq-bf-lcd-monitor-repair/ Look over the guide and check your board to see if your capacitors have bulged and need to be replaced.

I hope this helps, if so please rate our solution.

You need your monitor repaired or replaced.
Unlike a computer, there is not much troubleshooting beyond making sure it is plugged into a live outlet and turned on which you did already.
Good luck!

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.

My LGFlatron L194WT-SF monitor just stop working.Is there a reset button on it or something?
No reset button, more likely to have failed power supply due to bad caps, tha twill be the first place to look.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 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.

Hi My LG Flatron MDL L194WT-SF just stopped working. no power surge or power outages. Can this be repaired or is there an internal fuse that may have blown. it is just like new and hate that it failed....
They have an internal power adaptor which does contain a fuse. However the fuse is soldered to the board so you need soldering skills to change it. Also, if the internal fuse has gone then it's probably because another component such as the transformer has gone in which case it won't help.
Unless you know how to troubleshoot electronic boards a component level you're almost certainly out of luck here I'm afraid.
