Sounds like your main board is going out. It's cheaper to buy another monitor then fixing it unless you have a warranty.

Hello,

What do you mean that you were unable to get the native resolution of 1440x900? Are you saying that the resolution varries?

Since you mentioned that the mother board supports 1440x900, try to set the monitor resolution to that same resolution and then restart the computer.

If you will get the same problem, you have to make sure that the video card supports 1440x900 resolution.

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!

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.

For 19" monitor, I would expect more tahn 12vdc for the inverter circuits, some runs as high as 19vdc, but since you are getting 5vdc OK, more likely may be OK but should be check out, that 1000uf 16vdc may be used for the 5vdc power supply section, the inverter power supply section will usually uses 25vdc caps.
Do you see the backlight lamps flash on for second at all? You may need test lamp to verify if the inverter circuits are OK or not, since bad lamp can cause the inverter to go into shutdown also.
There are also BL_ON (about 3.3vdc = ON) signal and PWM_DIM signal feeding the the inverter circuits.
I would attach a12v car lamp such as 1157 to the inverter 12vdc power supply section to see if it can maintain 12vdc with load (do not turn on the power switch during this test since the power supply is always on even the power switch is not activated).

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Yes, you may have unstable DC due to bad DC filter caps, that will be the first place to look.
If you are going to DIY and already try the monitor with another PC, 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 LG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

I use thin flat blade screw driver to crack open the case, starting at the bottom edge first.
