Monitor turns on, acts like everything is fine and then - poof - no signal input....
I turn my computer on and the monitor turns on and evrything seems to be running smoothly - then the monitor blinks, then it goes dark and I get the message - No Signal Input. What can I do to fix this?!?!?!

Check the drive section also check the triger transistor, that provide power to the other section by the processing unit. check voltage & ampers before and after, check the electrolytic filters in that section. problem must be there. also check the SMD, if anyone from them is over heating.....

no input or signal means that the monitor is not receiving any signal from the CPU and if the power light is amber then and the cpu works fine then there could be a problem with the cable connecting the CPU and the monitor ...check the cable.
DVI and HDMI are the exact same signal, except that DVI doesn't include the provision for audio. Essentially the problem you're having is that you have the monitor set to auto input rather than HDMI input or DVI input. Setting the monitor to not look for any input you plug in and defining the input should cause the hunting wait to be eliminated.
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.
This box appears during normal operation if the video cable becomes disconnected or
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.
The Power supply inside the monitor can be hazardous and donot open the monitor while power on.
Donot work with the monitor when it is open and the power supply is on.
If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate
that the monitor is out of scan range or that you need to check the signal cable.
Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.
Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.
With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.
This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.
When a computer beeps on start up there is a crucial input output piece of hardware no working. If you have any experience with computers check to make sure everything is conected right. I inclued a link for support for your computer. Larry
If the bios setup is running evrything is ok except the hard disk.
To find out if there is any problem with monitor just put off the monitor and disconnect it from the cpu. Then turn it back on. If the no signal message is coming, then monitor is ok.
Your hard disk is the main suspect
If the same blue screen comes then monitor need repairs.
You may also try with another monitor on your computer to see the results. If the sane happens it is the hard disk
The monitor will display that message until the computer starts and outputs a valid signal to the monitor.
If the computer is on and you still get that message, then you may have
a bad video card/video circuit or a bad cable between the computer and
