A number of things can cause "No Signal" on a monitor

1) Check the cable between the monitor and PC is properly connected
2) If the PC has more than one display port try changing the display port the monitor is plugged into
3) Try an alternative cable between the monitor and the PC
4) Check that the correct input is selected on the monitor

Hi 13ambreuer

"Signal out of Range"
is a problem between the graphics card, monitor, motherboard or graphics card port.
if you have to do troubleshooting on the monitor and display card, proved no problem to it. This means that the problem now is the motherboard and graphics card port.
(But should remember, problems ram, power supply and processor also causes the same error) * Sometimes *)
mean here you have to do the troubleshooting on all hardware on your computer

thnks&regards

Hi Barb,

On the Toshiba A70 you should try holding down the fn key at lower left and pressing the F5 key which is the video transfer keyboard command for pretty much every Toshiba laptop. Otherwise, their little pictograms on the F keys almost always have a tiny representation of a laptop next to a monitor.

Hope this is helpful.

That sounds like a display/resolution setting problem on your PC. I doubt there is anything actually wrong with the PC or the monitor, since both work with different combinations, so its most likely just a setting.

Some monitors don't display anything when they get a signal/resolution that is not compatible with their displays. I would try changing the display settings on your computer with your old monitor, then switch monitors and see if your newer monitor works.

Here's how to adjust the display resolution:
If in XP, right-click on the desktop and go to Properties, and select the tab for display settings and adjust/lower the resolution. If in Vista/Win7 right-click the desktop and select Screen Resolution/Display Settings and adjust it there.

At your dads end, does it show that his webcam is being viewd..? It could be that there is not much light at your dads end.

your monitor has came in contact with some magnetic material remove all the things containing magnetsfrom around it and leave monitor unplugged for 1 day and then start it will work fine
pls rate my solution

Check the information at Viewsonic's website regarding their warranty:

http://www.viewsonic.com/support/warranties/limited-warranty/

If you have your proof-of-purchase and it shows the monitor is less than a year old, it would be covered. You would need to follow the procedure on their website to have the unit repaired or replaced, but it would not be your job to try to fix it.

One of 2 possibilities come to mind. 

 

1,  The vga chord is loose on the back of the monitor.

2, Your resolution is set too high or low to be displayed.

 

The blinking light means that the monitor is either not getting or understanding a signal.

 

Hope this helps.

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
