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 pressing F2 when you powered on the PC?
Ensure that the monitor displays the signal of PC and there is no issue with video signal. If there any issue, check with RAM.
1.If no, just press it to view the bios setting. Go to the third option below.
2.If yes and no display of bios, may be your BIOS ROM chip failed. Before that take the C-mos battery out and try again. Almost try to replace it or you must go for a new motherboard.
3.If yes and getting into bios, check for the hard disk detection. If it is detected, try again for booting. If it is detected and not booting, try to format. If it is not detected, try changing it into another SATA / IDE port. Still it is not detected, replace the hard disk.
When you power up the cpu check your smps is working? Then check num lock key on key bord if it is on and off when you press numlock then your cpu gives dispaly to monitor ok. but if it not constant on or off no change when you press num lock key then you have to open cpu cabinet. Refix RAM memory . Clean dust from motherbord chipset. Pull out cmos cell for 15 minutes so bios settings are reset to defaults. then check. refix all connection to mothebord like ATX power supply from smps.
Hi How old is your TFT Monitor? It looks like the Monitor has got some problem. First, make sure the cables are connected correctly. Try Changing the connecting cable (between monitor and pc) with another one. Try using another monitor with your pc & using same cables. If the problem persits, pls try your monitor on another Computer. This is all what you can do, if the problem wasn't solved, then maybe the problem is in the monitor that you need to take it to a specialit to repair it for you. I hope my steps were helpful.
Your laptop - are you running it plugged in or on batteries? Many times laptops have power configurations set for the display of the screen (brightness levels) to help with the power usage while running on batteries.
A video signal from the motherboard goes to the LCD screen through the video cable. The video cable connects to the motherboard (or video card) through the connector 1. The video cable connects to the LCD screen through the connector 2. The video cable (in most cases) is also responsible for supplying a necessary voltage for the FL inverter board. The video cable connects to the FL inverter board at the point 3.
This would usually indicate that there is a problem that is causing your computer to not boot correctly all of the time. What you have described could be many different problems and without more information I cannot say which one it is.
1. Hard drive. I have ran into Hard Drives that for some reason do not start up correctly right away when you put power to them. This can cause the initial startup to hang possibly indefinitely. 2. Video Card. Something probably firmware is causing your video card to not start up properly when power is first applied. 3. PSU. The power supply could cause similar problems if it cannot supply enough power because the highest power draw is when you first turn on the computer. When you push the reset button the power is already being supplied to most of the components and the ones that did not have enough power to start properly before can do so now. 4. CPU. If the CPU has some minor problems it can cause similar problems. In any case to fix it you can try clocking down the CPU but you are better off replacing it. 5. RAM. I have had similar problems with RAM. Clocking down the RAM fixed the issue. 6. Settings in BIOS. I would check to make sure the setting for init display on boot is set for PCI-e.
