LG L1930B 19" LCD Monitor Problem... HELP

Hello my friends, I have a LG L1930B 19" LCD Monitor, and since a week it shows me a green stain in the left side of the screen. That stain is just like a line that begins in the top of the monitor and ends in the downside. It´s a green line that seems a 80´s monitor. What I can do. It appears 10 minutes after I turn on the device. Please Help Me...

Thanks from Venezuela

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!

My L1930B display darkens right after switching it on. The image of the computer appears only for a millisec. If I keep trying switching on and off, it begins working, but usually it doesn't. What could be...

If not a bad kettle lead or loose connection at the monitor it could be:

Failing inverter, also maybe powerboard capacitors leaking or not holding charge. flicking the power switch will cause it to fail more quickly, repair or replacement I'm afraid

LG Flatron L1930B lcd monitor - 3 vert. stripes, center one dead

sounds like the pixel controllers have gone bad or one or more of the color (RGB, RED, GREEN, BLUE) controllers have gone out. this is quite common in lcd monitors/tvs and is usually caused by pressure on the edges of the screen (you grabbed it too tightly when moving the monitor) or just faulty controllers. they are expected to eventually go bad, ask LG for yourself, they will tell you the same thing. If you just bought it, that can be considered a mfr defect that they will replace, IF IT IS IN WARRANTY!!!!! Unfort. there is no fix due to seal that placed on the actual lcd panel inside the plastic casing. Youd spend more money trying to find the part and install it than just buying a new monitor. hate to say it but im an avid gamer and have gone through about 4 lcd monitors in tha past 3 years due to everyday use

Monitor suddenly goes black

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
