Blurred "No Signal" in the TFT when only power cable is connected.
I am having problems in viewing the display when I boot my PC. I hardly could see anything (not even the bios). I have an acer 17" TFT monitor. I noticed one thing strange. When I connect my TFT with the power cable and power it on, the 'no signal' text which comes, is blurred. There is no problem of getting the 'no signal' page, as I have not connected the VGA cable yet.
Is this a problem with my TFT, or do I need to check the other hardware's like, VGA card, RAM or the motherboard. It could be a problem with the OS as well. I have no clue. Can someone please help.

have you tried going to menu and setting back to factory defaults? also, disconnect power cable and leave unplugged for 1 minute. Plug back in then see if problem is still there. Otherwise, something is wrong with the monitor that will need serviced or exchanged.
Please check whether the monitor is set to the correct settings. If you feel its incorrect, most LCD/TFT monitors come with an auto set up button which will restore the display to one that usually works. In case it still doesnt work, you might need to connect your pc to a different monitor and check the display settings. You could also try to download the drivers for this monitor and then re-connect the monitor and see if it works.
Problem from motherboard side.
- No display from motherbaord circuit (Display IC)
- Try to figure out with PCI Display card or
- Try to connect different monitor or this monitor to different computer to cross check your dignosis
some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.
if your monitor is not connected to a pc, then it cannot find a vga signal input and therefore go into power saving mode, which is indicated by the orange light, but as soon as you connect to the pc and power on the light will go green and the monitor will power up.
