Here are the service manuals: http://elektrotanya.com/?q=showresult&megnev=LG&megnev2=L194WT%20&kategoria=&kat2=all

I usually open it at the bottom edge first and work it all the way around using thin flat blade screw driver.

It's not glued!!!! It's clipped together...and DON'T take out the screws first...

First, turn the monitor upside down and look at its thin edge. See where the grey bezel meets the black case? That's your clip point, all the way around the monitor. The reason you want to start here? This monitor is VERY tight, and there's a good chance you will mar the plastic, so it might as well be in the least visible place.

Next, fit a plastic trim removal tool (you have one of those, right? Right!? :) ) in between the black and grey plastic, halfway along the length of the monitor. If you have difficulty getting it in, run it back and forth until you find a loose point, but you'll eventually have to come back to the tight spot.

Here, there's a little bit of finesse required...you have to pry the grey part (which I will start calling the "bezel") gently upward, not away from the black plastic (which I will call the "case"), perpendicular to it. This will pull a clip up out of its slot. When you feel the clip release, now you can move it slightly away from the case, but don't remove the trim tool. Keep unclipping the rest of that side.

Once you've gotten the hang of it, do the next side. This bezel is particularly tight, so don't start at the edge...you will definitely damage it. Once you've gotten two sides loose, the whole job becomes easier, but still stay patient and careful, because there's a lot of potential for damage.

Now that you've gotten the entire bezel off (and the hard part is over with), hold the LCD in place as you turn the assembly face down onto a soft cloth, like a blanket or comforter. Now you can remove the four screws from the back.

Lift the case off and remove the two screws holding the switch assembly. This will lift off easily.

Lastly, partially remove the silver tape holding the electronics case on the back, carefully remove the connectors (remembering their positions, of course), and you're ready to play electronic doctor. I'm posting this with my newly repaired L194WT. :)

LG L194WT picture problem


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

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.

Hi, I turned my computer and monitor off as I normally do last night and when I came downstairs this morning to turn my computer and monitor on, my monitor didn't turn on. I pressed the power button on...


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!

HOW TO CHECK A LG FLATRON L194WT-SF MONITOR FUSE, THE REAL PROBLEM IS HOW TO REMOVE THE BACK COVER


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.

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.

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.
