SOURCE: 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.

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:

SOURCE: 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.

Flatron lcd monitor l1930b in power saving mode how do i get it out of


Most every television would have an on/off setting for power save mode. especially an LG product. it contains settings like backlight brightness, or to go into sleep mode when the tv is on but inactive. i would try looking into your tv's menu for things like Parental Controls and all those other customize-able settings. best of luck!

I want by a power supply to LG FLATRON L1510S


The question is not very clear and if this is a commercial request it would be better that you can contact any of the power supply distributors in your area. However if the LG SMPS is required it must be sourced from the LG service support.
If you need to check on the SMPS please check this link:

Hello my flatron l206wtq-bf doesnt work the light of power flash blue and the monitor doesnt open do you have a solution for me thanks


Hello,

Your unit has a power supply that has failed. When the power board starts failing you may get a wavy display, it may be slow to show a picture or you may just get the flashing power button light that you have. The problems are caused by parts called capacitors that have bulged and failed. Here is a link to a repair guide for the LG L226 that uses the same power supply board as your unit.

http://www.ccl-la.com/blog/index.php/lg-l226wtq-bf-monitor-repair/

The dis-assembly information is almost the same to.

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

alkarim 15, Are you looking for an "open frame" switcher or a "open frame" linear dc supply. Does it need to have regulated output or if linear type just brute force output.What is the current requirement of the circuit you will use with the power supply?

My LG Flatron 1710S computer screen doesn't have any power. Sometimes the power light will start flashing but most of the time it stays blank.


This is a common issue, the power supplies in LCD monitors fail prematurely. (if your monitor has an internal power supply) , Double check all your power connections, but it sounds like the internal supply is toast, (its a simple capacitor replacement to fix, but cost to do this job seems to always outweigh a new monitor purchase) sorry to be the bearer of bad news.If you find my answer helpful albeit poor news, please use the thumbs up feedback.

LG L1930B 19" LCD Monitor Problem... HELP


When an LCD Monitor starts to respond like this it is due to one of three reasons a power supply is not generating enough power to properly power the LCD or the LCD's backlight is beginning to burnout, and last the inverter is bad. These things all can be replaced, but it is not worth the cost! Easier and cheaper to buy a new one!
