Adjust the video height on MAG lt716s computer monitor

The laptop screen turning black is what it's supposed to do.
Make sure your computer has the correct output, and the TV has the correct inputs. Very few laptops have analog video out (like the 3 RCA jacks, or the round S-Video jack), but some newer TVs have VGA inputs (Often blue, trapezoidal shaped plug with lots of pins).
If your TV and Laptop are compatible, make sure you've set the Input on the TV to the correct source. You will need to consult your TV manual for this.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

You need to set the PC VIDEO resolution to the native resolution of the monitor to get correct aspect ratio (not adjustable at the monitor, the adjustment is doen at the PC VIDEO card setting), you need to find that out from your monitor owner manual.

it is a problem signal cable of the monitor open the monitor test the continuty of 15 pin signal cable
if pin no 13 & 14 (hsync & vsync)are open then change the cable problem will be solved

souns like the dc-dc convertor board that supplies the backlight gone faulty possible poor soldering on board

When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

Try changing to a different video resolution setting. Most monitors work well with the resolution set to 1024 X 768. I'm not sure what operating system you're using, but here's an example of how to do it with Windows XP...

Right-click on your desktop...then click Properties -- Settings --
You can try different resolution settings in the settings window.

Good luck...and I hope this helps!
