My LG monitor displays rainbow color at the bottom half of the screen. how do i fix this? what part should i replace?

That is bad T-CON board which is part of the LCD panel assembly, not much you can do. You can try seating the connector on the T-CON board to see if it will solve the problem.

My monitor will display the picture for approx 1-2 seconds, then the word "analog" is seen and immediately the picture disappears. Bottom line: the picture won't stay on.

I assume that you have already try this monitor with new VGA cable and with another PC but still get the same result, just want to narrow down the problem before opening it up.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 VIEWSONIC nad other monitors to get some ideas what goes wrong:
Post back what you see inside so we can guide you further.

LG L1717S has no light

Hi, this is a common problem. One thing you want to observe is that the screen works, what's going on is that the screen LCD illumination doesn't work while the screen display is active. LCD's have screen lamps behind the screen, they are often called CCFL, (Cold Cathode Flouroscent Lamps). The inverter board in the monitor supplies High Voltage power to the lampls, so the colored wires should lead you to the lamps. This is the problem causing the screen to dark. You can research the model lamp type for an accurate replacement. Usually there are 4 or 6 lamps in LCD Monitors.

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it turns itself off, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. I used to check my LCD monitor and could see window image using flashlight and found out that Some of CCFL lamps inside were broken. The lamps are very easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you,

Flatron l1717s blank screen

Common cause of this is the VGA or DVI connectors not screwed on tight on either the back of the PC or the back of the monitor.

Also try removing power by unplugging for 30 seconds, sometimes that will reset things.

I have two lg monitors on spreat dispaly adapters

You don't need a driver for the monitors, the native plug and play driver in XP usually works as well as any manufacturer supplied driver. What's happened is XP doesn't recognize the onboard display adapter. If this is a name brand system (you didn't mention what type it is) download the XP display driver from the manufacturer's web site. If it's a custom built system, there should be a motherboard CD that came with the system that has the display driver on it. When all else fails, download System Information for Windows from It will tell you what type of onboard display adapter the system has.
