Hey hows it going,

My name is ArmyMason, lets see if I can get you going in the right direction. www.partstore.com might have a deal on the parts you need but I am thinking it would be cheaper for you to buy a new monitor or consider hitting up a local pawn shop for a cheap replacement. These parts can cost more than the whole monitor because LG buys parts in major quanity and we all know (WalMart effect) the more you buy the cheaper the price. So if you need to take it apart in the back of the monitor are a bunch of screws start unscrewing and make sure you know where they all go. tape them near the hole so that you can find them later. Once all apart, be sure to wear gloves, dont want anything to possiably contaminate you. (LEAD)... get the part number off the screen and look it up in that site. Order it and replace it. It is straight forward to replacing it.

Good Luck,
ArmyMason

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.

How to replace LG L196WTQ-BF Computer light bulb


Are you sure that the lamps (4) are bad and not the backlight inverter circuits.
Service manual: http://elektrotanya.com/?q=showresult&megnev=LG%20&megnev2=%20L196WTQ-BF%20&kategoria=monitor&kat2=schematics

Not all the LCD lamps can easily be removed, some of them you have the completely disassemble the screen to get the lamp asemblies out. Need to do voltage checking and caps inspection first, it should have 5vdc for the logic and 16~18vdc for the inverter circuits
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, 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.

LG Monitor L196WTQ-BF ..weird image stuck on desktop??


The "image" you are talking about: Is it there when the monitor is off? If so, you are correct--it's broken and must be replaced.
Is it on the desktop when you start the computer and does it stay there no matter what program you are running. If the answer is "yes" then I'm afraid the answer is the same.

I have a LG L196WTQ-BF flatron screen. Computer powers up but screen does not turn on. I lhave used this for a couple of years with not problems.The computer I am using is a HP Pavilion a430n.


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

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