Question about ViewSonic VE710b 17" Flat Panel LCD Monitor

1 Answer

Power dies when video signal applied

Monitor powers up momentarily and goes to standby normally with no video connected to it, but while its on, it lights up bright white, which does not appear to be a normal mode. Also, sometimes video is fine, but in most cases, the presence of a video signal from the PC's VGA connector to the monitor causes the power to the monitor to shut down completely. It is not going into standby; its going completely off (the power LED is completely dark). The monitor cannot be powered on while connected to the PC's video output, no matter how many times I press the PWR button. Now, if I disconnect the monitor from the PC, it turns on (LED green, white background) then goes to standby. Please note: the PC is NOT the problem, is OK, and works with its usual flat-tube monitor connected. The problem is completely with the ViewSonic VE710b. This is a good one, so please DO let me know if you can help me with this before I give it to my youngest son to tear up!!

Thanks,
James

I fixed this problem by replacing all the electrolytics 1000uF and 1500uF on the power supply/inverter board. All were either bulging or had burst at the bottom rubber seal. This cleared up all problems and I am using this monitor successfully at this very moment.

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.

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.

"no signal" showing on tv screen


  1. Make sure the HDMI cable is connected to the HDMI OUT port on the back of the PLAYSTATION 3 system. Connect the other end of the HDMI cable into the HDMI Input port of the TV or display monitor.
  2. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive power button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light --> green light --> then back to red light). This will ensure that you have held down the power button long enough to reset the Video Output Settings.
  3. Turn on the PLAYSTATION 3 system and once the system finishes powering up, the Video Output Settings will automatically reset to the standard resolution (or detect the current display output settings of your TV/monitor).

When I turn my monitor on, the screen shows the desktop momentarily and then goes black. If I turn it off and on a couple more times, the desktop will stay on and function normally. Where is the likely...


Try the monitor on another computer, to check-out the monitor.

Does the POWER lamp on the monitor stay on when the monitor goes black? If so, then the monitor probably is OK.

Try a different monitor, to trouble-shoot the video-card.

Magnavox 15mf605t/17 15'' LCD HDTV won't turn on


Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

My monitor gets switched off when i connect to cpu,the moment i disconnect it from cpu,its switches on automatically.what may be the problem?


One of two things:

1.) Your video card is 'stuck' in standby mode, which in turn sends a signal putting the monitor in low power 'standby' mode as well. When you disconnect it, the monitor returns to normal 'on' mode. Rebooting the PC should correct this issue.

2.) Your resolution or refresh rate are set outside the range supported by the monitor. When you connect the monitor, it starts receiving a signal that it can't display, so it simply turns off. You'll need to reboot the PC and press F8 quickly to bot into safe mode and correct the monitor settings.

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.
