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.

Here is a repair guide for the L196WTQ model that is basically the same unit as the L194WT. The repair guide has pictures and video instruction showing how to open the unit and what to look for on the power supply board. I hope this helps.

My L194WT -SF WONT WORK NO POWER USED SAME POWER LEAD ON DIFFERENT MONITOR NO PROBLEM


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.

LG Flatron L194WT Monitor no power


It can be as simple $5 worth of caps in the power supply.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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/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.

LG FLATRON L1953T-SF 17" LCD Monitor Has no power? I checked the fuse, it's OK, tried different cords still no go? would it be the power supply itself?


Did you inspect the caps, any bulging one? Measure the power supply to see if you do have 5v and 12v on the power supply/inverter board.
See pictures and websites so you will know what to look for:

L194Wt doesn't turn on when connected to power, no power light-nothing. This monitor connects directly, no transformer in the power cord.


You need to open it up and inspect the AC main fuse, capacitors (with bulging top/seal), burtn parts, etc. see example of failed monitors due to bad caps, lamps, transformers, etc: http://s807.photobucket.com/home/budm/allalbums
Post back as to what you see inside so we can guide you further.

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.

I have a L194WT LG Flatron monitor. One day it


Same problem started happening two days ago and ever since. I called LG and the product falls under a 3yr product warranty according to them (from my original purchase date of January 20, 2007). They will send packing slips to me so I can send the defective unit back to LG. I was told I am eligible for a replacement monitor - which will be shipped to me within 10 to 14 days (consecutive days, not business) - although I'm not sure what I'm being sent in return. My suspicion is that this monitor issue is a known issue by LG and they are quietly replacing the unit to those who follow through by calling CS.

Tips: Have your original purchase date on hand (in the form of a receipt) just in case they want proof of purchase.
