LG L1900E flickering after cold start

My one year old LG L1900E 19" LCD monitor, after 10 months of perfect working, started to flicker after a cold start.
It flickers all the screen as a stroboscopic light for a couple of minutes after I switch it on, or after coming out of sleep mode. I said "cold" start because this only happens when the monitor has been sleeping or switched off for a while (I didn't measure this "while").
After stop flickering, it works fine. If then I switch it off and on, there's no problem, because it is "warm".
It's not a video card nor drivers problem, because it flickers with my desktop and laptop. Neither an interface problem, because it flickers using the VGA and the DVI conectors.
Thanks

    I don't understand you fully. What do you mean with "rendering" and what is the setting I can adjust to correct the problem?
    Thanks

    Same problem with my LG L1970HR-BF, worked perfectly for about 1 year to 18 months and then sudenly started flickering for about 2-3 minutes ever time the monitor "cold starts".

    This is not a software issie because I have another samsung LCD to the left of the LG that is older but works without flickering allways.

    I noticed if I switch the setting on the monitor to shot more light it flickers less.
    I will probobly solve this issiu by throwing the LG piece of ... out and never buy an LG monitor again.

This is probably due to a bad solder joint somewhere. Bad solder joints can effect a unit in the reverse also. IE works at first and then dies after it gets warm. Think about how metal expands when it is heated. And contracts as it gets cold. If there is a hairline fracture on one or more component joints, this would cause it to not have such a great or solid connection when it is cool, or contracted. As it gets warmer, the solder expands therefore filling the void and giving it a good connection.

Regardless, it will likely only get worse over time. If you're handy with a soldering iron, pop it open and reflow all the joints. Especially the ones on the transformers and copper coils. Best to hit them all, excluding the tiny surface mount devices.

Monitor flickers about 2 minutes after turn on. the flickering starts from the left and it eventually becomes a black screen. the monitor is 8 months new.


Unless I have the model number wrong (F1903), this monitor was relased in 2004. If it is 8 months old then it should be fixed under warranty. This can be bad problem in the bcaklight inverter circuits or bad lamps due to bad soldering works, bad power supply, please look here to see hwat is involved in repairing the monitors: http://s807.photobucket.com/home/budm/allalbums

Hello,

I would check the capacitors on the power supply board first. This is the most common problem with LCD monitor after a year or two of service. Open the back and look for bulging capacitors, replace any that you find and you should be back going again. Check our web site at: www.ccl-la.com/capacitors.htm for pictures and information about this common problem. If you need to get parts or have over questions let us know at tech@ccl-la.com.

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

If you have a capacitor tester.. i'll be much better at least you would know which caps that actually failing..
I would replace all the caps if you dont have the tester.. and while your at it. try to resolder connections and some parts like transistor etc.. maybe they have "cold solder"
