Question about ViewSonic VA720 17" LCD Flat Panel Monitor

No Power When the power and monitor cable are connected to the computer there is no picture and the power light is not lit. Pressing the power button does nothing. However, with the power cord plugged in and the monitor cable not hooked up to the computer, the green power light is flashing, and the power button seems to work as pressing it will make the flashing of the power light to stop flashing.

This is a very common problem. Theres a guy on ebay that will fix it for you for 24 bucks plus 5 bucks shipping. When you open the monitor, on the back panel there are 2 boards. One is a power supply board, the other is the interlogic board. The power supply board is where the problem is. I do not know the exact component that needs replacing as I did not test this yet. I do not have the proper test equipment. For 24 bucks, I'm just gonna let the ebay guy repair it. I will report my results here when I get the board back. I'm also gonna mark the components so I know what they replaced.

The ebay guy fixed it for me. It cost me 29 bucks including the shipping. It was easy to take apart, you just ship him your power supply board and he repairs it. I marked the components on the board and he replaced quite a few of them. The monitor has been working good for about 2 months now since he repaired the board. Look for ebay user resurrectek. Check his items for sale. On of them should be to repair the board. He was very helpful and even provided tech support to put it back together!! (he changed the plugs on the board that I had marked, so I didn't know where the wires plugged into.) I highly recommend using him to repair it. It's alot cheaper than buying a new monitor.

Thx for the reply, it's fine when plugged into my older machine & when I connect the acer to the tower it came with it works perfect till I shut the system down. I set the power saving mode to shut the monitor down after 1 hour when this problem started. Turned off the power saving in safe mode and tried it again but got the same results. Is there another setting I am not finding?

Just leave me a reply if u or anybody else can help, Thx again & Peace... The Beast..

Hi, It's either the LCD monitor is not receiving video signal from the PC or something is wrong with the input circuitry of the monitor. 1. If it is the PC, it could be anything from the video card, memory or something else; 2. If it is the monitor, you have to open it up and diagnose the problem. This would probably require component level repair. You have to be familiar with the use of a soldering iron, a VOM and circuit analysis to be able to do a DIY. If you can borrow or have access to a known good 2nd monitor you can confirm which one is the issue, PC or monitor. Hope this works out for you. Pls post again how things turn up that we can further resolve the problem. Good luck and kind regards.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can

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.

Shut down my Acer 2480 wrong by pressing the power button. Now it doesn't reboot or boot up. I tried to pressing F2 to reboot but it doesn't do anything. Any suggestions?

Look at the power indicator:
If it is not lit, no power is being supplied to the computer. If the computer has a battery, it may be low and unable to power the computer. Connect the AC adapter to recharge the battey pack and make sure the AC adapter is properly plugged into the computer and to the AC power outlet.
If the power indicator is lit, check if a non-bootable (non-system) disk or USB thumbdrive is in the computer. If so, remove it and press Ctrl + Alt + Del to restart the system.

Pressing F2 by itself is only used to enter the system's BIOS on startup. If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on.
If pressing any key does not turn the display back on, check the following....
1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level
2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display
3. Backlight might be turned off. Press Fn and F6 to turn on the backlight.
4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.

Computer monitor don't work at all.

So basically your monitor's power supply system died.
Nothing much a non-technician could do about it.
Get it repaired, if under warranty, get a replacement before the coverage duration expires.

My compaq presario V6000 is stop working out of blue..Don't know why..the power cable is connected but hit the power button,nothing happens..any solution ??

Disconnect all cables from the computer. Press and hold down the power button for about 20 seconds. Reconnect only the power cable and try to turn on the computer on pressing the power button If it turns on then good otherwise, switch the power cable of the computer with the power cable of the monitor as they are the same cable as the power cable could be bad but this rarely happens. Open the computer and see if you see any light on the motherboard, if you do then the power supply is bad. If you dont then both power supply and the motherboard could be bad.

No picture on monitor 997M

One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.

what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.

Solution: The following is monitor troubleshooting. If your monitor receives a proper display until it gets into Windows 3.x, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, or Windows XP please refer to document CH000192.
Monitor is not on Make sure the monitor is on. If no power light (green or orange light) is seen on the monitor display try pressing the power button until it comes on. If no light comes on after several attempts continue to below connections not connected properly.
Computer is asleep If your computer monitor was on and you stepped away from the computer and upon returning it was black it's likely that the computer is asleep. Try moving your mouse, clicking the mouse buttons, and/or pressing any key (space bar) on the keyboard to wake it up.
Connections not connected properly Make sure that you are connecting the monitor to the back of the computer in the 15 pin (illustrated below) or older computer 9 pin connection.

If the computer is properly plugged in, make sure it's getting getting power.
If you are not receiving power from a known working wall outlet and if the power cord is removable, replace it with the one connected to the computer and attempt to power on the monitor again. If the monitor still does not get power or it is not removable, it is recommended that the monitor be replaced or serviced at a local TV / Computer repair shop.
If the monitor is receiving power, check the status light.
If the light is orange or flashing ensure that the monitor is not in a suspend mode by moving the mouse or pressing a key on the keyboard. If the computer does not get a display by moving the mouse or touching the keyboard, turn off the computer and monitor and reconnect the data cable from the back of the computer, and if removable, the back of the monitor. Turn the computer back on; if you still encounter the same issue, continue reading through the other possibilities.
Monitor settings are not correct Ensure that the brightness and contrast is turned up or attempt to adjust the brightness and contrast. If adjusting the brightness or contrast has no affect on the monitor continue reading through the other possibility.
Does the computer beep when it is powered on and/or does it appear that the computer has activity? If the computer does not beep or beeps abnormally it is possible that the computer itself is experiencing a hardware issue or is exhibiting .

Hope this works for ya/ Please dont for get to Vote.Thank You
