Please go through the following check list.
1- First of all you check the power of LCD screen. If there is any power indicator then it should come ON.
2- Check if the brightness control is not selected at the darkest setting.
3- If power is present on LCD then check the connection with the computer. Remove the connecting cable out from computer and re-fix it again. If you have the cable which also has connector on the LCD side then do the same on the LCD side.
4- If you have VGA connector then check if there is any pin bent inside the connector. The pins inside VGA type connectors are not so strong and some times they easily get bent while installing the cable.
5- If none of above work then finally check the LCD with another computer. If LCD works with other computer then there might be 2 reasons why it does not work with existing computer.
a- There might be some issue with PC hardware. You can check this by connecting some other monitor with the computer. b- The resolution selected on the PC might be not acceptable by the LCD. But in this case you should get at least some text on LCD when you turn ON the PC. I am not sure that in your case some text appears after turning ON the computer or after resetting it.

My hp 1502 lcd monitor only shows a white screen


If you don't use an identical monitors, then they may not work if your video card can not handle them. The "check video cable" it means the monitor does not get a signal, and it does not mean that the monitor is a problematic monitor. You can test this monitor as a single monitor (and try to connect it using first video port, and then move it to the second video port).

Monitor says no signal


You will need to check that the connection with the computer is firm and also the correct drivers are loaded on the computer.

You can get the driver from this site and install on the computer.
You will have to select the operating system of your computer.

Hope this helps.

here is the simple test to detect hardware malfunction.
on every monitor these days whether its CRT or LCD already programmed inside self test.
detach your cable data to CPU and power on your monitor. if its displayed self test on your screen mean its OK and something wrong with your CPU, could be VGA error.

if its just black display mean some is wrong with your monitor.

if you post more detail maybe we in FIXYA could help.
thanks.

Why the computer doesn't turning on but the green light is lighted


You may want to verify if the computer is the one that do not turn on. Please check if you see the fan on your computer is working and the LED in the mother board is lit.

IF the computer is working and no display on the monitor, despite seeing a green light on the monitor display, this means that monitor is well connected and communicating well with the cpu. Better check the inverter light on the monitor. Replace busted lights. These are responsible for the image you see in your lcd monitor. If the inverter lights are busted then you'll see only black screen.

You might need to change the screen refresh rate. Go do Control Panel> Display> Setting> Advance, choose 60 Hz. In order to make your Monitor able to display, restart the PC, press F8 on the keyboard frequently upon splashing ( 1 or 2 seconds after PC restarts). Select enable VGA mode by pressing up arrow of the keyboard> press enter. The display should look bigger, then you can start adjusting the screen refresh rate to 60 Hz

You buy a new LCD Monitors, now still not working., if that new LCD Monitor is OK, then check your VGA Card, its inside the CPU maybe its broke or not connect properly inside. This are the cause of not displaying in your LCD Monitors.
If you here some beeps of your CPU then find out how many beeps and tell us here immediately.
