Matteson1914, If unplugging from wall outlet and then plugging it back in 1 minute later will not stop (correct) the problem you have, then I would suspect (as always) the "switch-mode-power-supply" has a serious problem. Whenever an lcd with CCFL backlighting starts doing very strange and weird stuff, I would suspect the power supply as the culprit and look at it first! If your display is a VL1918 then you WILL need to read all the other posts by clicking on "VL1918 (black) monitor" that is highlghted in blue. If you do any capacitor replacement make sure they go in (installed) correctly(++ - - ) and that new ones are rated for 105 deg cenitgrade (not 85c) If installed wrong they will fail immediatly and you will need to do-over!!!! 12fixlouie

Check cable connections from gpu inside pc tower. If you have a second monitor or can borrow one, see if that monitor works. If colours/image are distorted then you may need to replace the gpu.

There is a couple of possibilities and things to eliminate.
Your monitor is acting like it's not getting a signal. First make sure your video cable is plugged in and tightly connected with the screws fully torqued down. Test the video card by wiggling the connected cord to see if the monitor comes on even temporarily. Try opening the case and re-seating the video card.
If you can get the monitor to stay on long enough go into the control panel and the properties page and make sure you screen saver or power management for energy savings is not set to zero.
If it's new you may have to go the your control panels add remove components and un-install the video card then re-install the driver again. Windows is famous for this requirement.
If you are using this as a second monitor connected to a laptop you will have to hit the corresponding function key on the top row of your keypad, F4 or ?...., to open the port to avail the signal.
On a mechanical level at the monitor depress the Menu button and try a few sizing adjustments to bring the picture back to shape.
Cable - HDMI, USB, VGA ? You may need an adapter to get the signal VGA to HDMI etc.
We need more information but try these things to start.

Can you try this monitor with another PC or this PC with another monitor? We need to find where you lose your signal at first before going further.

Your monitor is going into power saving mode. When it receives no video signal from the computer, it will stay powered for a few seconds before giving up and presuming the PC is off hence why it stays green for a while, then goes orange.

The problem is with your PC not the monitor(s)

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.


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.

Monitor problem


erickalin - it sounds like your computer might have shut down and failed to come back up again. If you have access to another monitor, try hooking it up to your computer instead of the one you normally use (that won't stay on). If the second monitor won't stay on, the problem is your computer. You might have to take it to your local computer geek or computer store to get serviced. If your computer DOES work with the second monitor, you might need to have your monitor serviced or replaced. Good luck!

supposed2b, I think you have the same problem, although your computer doesn't even sound like it's powering up. Your power supply might be faulty or an internal component (CPU or memory most likely) of your computer has died. Double check your power connections and ensure that when you press the power button you hear the computer start up and the light on the front comes on (hopefully green or blue, but not yellow or red). Again, you might need to take your computer in for service.
Good luck!

Computer monitor wont stay on


LMAO it sounds like it is going into power-saving mode because there is (or it -thinks- there is) no signal. Has it always done this? Try punching up the controls when you turn it on and changing its behavior through those menus. Doublecheck the monitor's connection to the computer. Alternately, if it is connected and a display is coming up for those 10 seconds; perhaps just going into sleep mode, with the power LED changing appropriately; you can look up the exact model, and find schematics and previously solved instances of your case.
Even if you can't find those, you could read through some introductory electronic circuit books (and the internals of the monitor...unplug and read the books' safety bits first) and determine what went bad and how to replace that component.

Sony hmd-a400 monitor


Next time you get it running, right click my computer>properties>hardware tab>device manager and look for your monitor on the 'Monitors' '+' sign and right click>delete. Also check 'Display adapter' see if the correct driver is displayed. Re- boot and let Windows re-install monitor driver(it should list it as 'Sony')
