When I turn on my pc, the power light of the monitor is green for ~3 secs. Then it goes amber and the monitor displays "power saving mode" and it goes black. When I disconnect the monitor from the main unit the light goes green again and the monitor displays "searching for signal" or something like that. I again connect the monitor to the main unit and the monitor goes back to the power saving mode. I checked all the switches and the power cords, everything is ok. HELP! (F1, F1, F1!)

Re: monitor doesn't work
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode.
If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead.
Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.

Hi, if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .
1. Bad video card 2. Bad video software
To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.
If the light changes to green and back to amber the video port on the tower is bad
Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.
I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.
Most LCD monitor (depends on the brand) power indicator light will either turn from Green to Amber, or flashing Amber, or flashing green, when it does not detect video signal feeding it. So it may be normal with your monitor. Are you haivng problem with the display? If it displays he pictue OK then there is nothing to worry about.
If it is still in warranty call the manufacturer.
if not give more info email@example.com. May be somthing simple like a cable
shutdown computer unplug then disconnect the video cable on the computer from the monitor, plug monitor back in and turn it on, there should be a display that says no video source within a few seconds, if unit is working properly. shutdown and connect video again and then reboot computer. sometimes it just takes a compleat power disconect to reset things,
The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:
Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.
Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.
If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber.
When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps. Try this as it is a common problem I find a lot. Good Luck.
