Question about ViewSonic Computer Monitors

1 Answer

Monitor screen turns off almost immediately

This LCD monitor flashes a normal screen for an instant, then there is a pop up message "NO SIGNAL ANALOG". Then the screen goes blank and the monitor changes to power save mode (orange light) within a second or so. Monitor is on just long enough to see that the picture is there. Both PCs I tried it on are running Windows XP with the same results. The monitor menu won't come up when you press the "1" button, so I can't do any reset or change settings. I attempted to use a VGA to DVI adaptor to see if the problem was with the 'D' connector, but Viewsonic apparently uses a different DVI pin configuration than most. Results were the same using another VGA cable. I don't have any other video source to test with.

    Sorry, the hookup is a simple VGA cable that worked fine for years on my sister's PC. There was a small fire in her home adjacent to the PC a month ago. The monitor worked fine for another two weeks. Maybe the fire caused a power problem: the power strip it was plugged into suffered heat damage. Apparently it cannot acknowledge the analog signal from the cable and so it shuts off. Like I said before it has a perfect picture plus the NO SIGNAL ANALOG message for a quick flash before going dark and the green led changes from green to orange.

I have a samsung 17'' lcd monitor.when i power on my monitor without data cable i got a message on screen CHECK SIGNAL CABLE.when i connect data cable my lcd is going to power off.please help?


The message says that the monitor doesn't receives signal - which is normal. Since the problem appears only after you plug in the cable in means that the problem is located there - something is wrong with your pc, most likely the video card has died.

Use the self test feature.. follow the steps..

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
damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
monitor.
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.

Warning

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.

Monitor screen begins as computer is booting up and then screen goes black. Message says there is no signal.


If the power light dims or changes color after the no signal message comes up, that means the monitor went to sleep.
While the monitor is plugged in and on and the computer is also on, Try unplugging the VGA cable from the monitor. wait 30 seconds and then plug it back in o see if the power button light comes back to normal color and the screen flashes on.
If not, then the monitor is not getting a signal from the computer.
If using a desktop computer,Try a different cord or try the monitor on another computer.
If using a laptop, you need to activate the laptop to use an external monitor. That can be done through the display settings, OR, most laptops have a shortcut key feature which usually involves pushing the Fn key and one of the F keys at the same time. The F key may say CRT/lcd or have a picture of a monitor and a screen.
If the power light does light back up and still no picture, There may be an internal issue on the monitor

You could have a faulty inverter board or faulty CCFL lamp which can cause the screen to flash.

Monitor flashes on and off


When it comes back from BLACK is it like a Power ON with the display intensity coming up gradually, OR does it POP back with an INSTANT ON - like appearance.

Slow appearance would indicate basic Power loss to the Monitor, or failure of the internal Low Voltage inside the Monitor's Power Supply.

Instant OFF/ON would indicate either:

1. Loss/regain of Video Signal

2. High Voltage Loss/Regain within the Monitor. This would be accompanied by a 'crackly' high voltage 'staticy' sound.

So, what's the further story???

Screen shows message "no input signal" and monitor goes to sleep.


monitor show "no input singnal" error masage when not gating any type of video singnal ,
so if u realy check your monitor wires for correctty plugged in .
then:-

Two possibilities:

either the video/mainboard of the monitor is defective; or
the video card/ CPU is the faulty.

A way to verify is to try the PC with another monitor or to try the monitor in another PC.

thanks
