The monitor turns on but says "no signal" - ViewSonic VA721 17" LCD Monitor

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

Try a different monitor. If that works, your monitor has gone bad.

Well, at least you got it sorted out and everything is working fine now.

Massive hardware failure - the video card is no longer functional. You will need to take it to a repair shop to have it diagnosed properly.

The no signal can either be "no signal" or a signal that is out of range. Check first by connecting the monitor to a known good video output (ie another computer). If that works, then the problem is with the source and not the monitor. Sometimes the source computer has its resolution set too high and the monitor will not be able to process that resolution. The no signal message will occur then as well.

make sure the monitor is turned on, if yes check the signal cable of your monitor

It is probably a bad INVERTER and / or backlight fluorescent bulb.

Problem
1. turn on computer
2. monitor receives signal, it looks like its working
3. it goes through some steps and then the monitor says "no signal" and kind of stays in limbo with fans running, etc.

Solution
One possibility is that computer is looking for drivers for you video card. It could be hung up looking in the wrong places. Remove all peripheral hard drives and memory sticks. Try again.

This is normal. The monitor is telling you it is not getting a signal from the computer, which is true because you've turned off the computer. The monitor power is still on, however. The monitor power is not controlled by the computer power switch. Just turn it off with its power switch after you shut off the computer.

First you sec your monitor power cable is not loos or power in properly if ok then you sec your monitor VGA cable is properly conect to your pc if ok then you disconnect your VGA cable in your pc then you power on your monitor and sec that youre monetor screen. show a masege or not masage like tiis : CHEEK SIGNAL CABLE or NO SIGNAL : if show this signal then you men your display card is not responding or monitor shows nothing then you meen your monitor is faulty then contact any monitor techenican and solve your monitor problem.
