Question about ViewSonic VA702b 17" LCD Monitor

1 Answer

ViewSonic 17" I tried 3 different monitors attached to an Acer 5200 and all three are telling me there is no signal. I've exchanged at least 10 of these monitors out throughout my school district and never had this problem before. These were brand new monitors straight out of the box.

I would check to make sure you have the proper input settings selected and also make sure that the resolution is set properly. If those are good then I think you should try hooking up a different monitor to your laptop and see if that works; if another monitor doesn't work then there's a pretty good chance your VGA output it probably bad.

LCD monitor (viewsonic va720) "No signal"


You will need to disconnect the VGA cord that is connecting the monitor to the hard drive. Once you have that disconnected, try attaching another cord to determine if the cord is the issue. If you dont have another cord to test, then you will have to purchase another one from your local computer parts store and attach to determine if that is the issue you are having.

If the cord does not work, then you will have to take your monitor into a repair shop as there maybe an issue with the receiving port on the monitor.

I hope this was helpful and thanks for asking the experts.

My omnitech monitor is turning red when it wants to. no certain program just whenever


Colours on the screen are generated by "mixing" the 3 primary colours.
Of the primary colours is RED.
So, your LCD monitor is not receiving signals from your computer,
specifying the other two primary colours.

Check the data-cable between your computer and your monitor,
to ensure that the connections are tight at both ends.

Try a different data-cable.

Try your monitor on a different computer, with two different data-cables.

Try a different monitor on your computer.

It could be the video-card inside your computer is failing to "send" one or two of the primary colours.

Osdlock on my computer desktop for 17'' monitor


You are having a problem with the OSD lock on your ViewSonic E70f Monitor. Is that correct?
If so, please follow these instructions to unlock or lock your monitor.
On some display devices, there is an OSD Lock that locks all current control settings and prevents access to the control menus until this mode is unlocked.
The method for unlocking the OSD is different for different monitors, but will be one of the 2 below. If the first method doesn't work, try the second.
Method 1: Press and hold both the [1] button on the front of the monitor and the down arrow button for 10 seconds.
Method 2: Press and hold both the [1] button on the front of the monitor and the up arrow button for 10 seconds.
Note: These same buttons, when pressed for another 10 seconds, will lock the OSD

Please let us know if you require any further help with this matter.

Viewsonic vp930b-3


MY VP930b has the same problem.
It takes a very long time (5-10 minutes) before it becomes normal.
