screen turning on and off

ds500

The screen on my V3-771G turns off every few minutes but stays powered on, i am running off mains power.

 

It stays off for only a second then comes back on again.

Move the screen up and down and see if it does it while being moved.

If no, Right-click the desktop and choose Screen Resolution/Advanced Settings/Monitor. If enabled, place a check beside "Hide Modes That This Monitor Cannot Display" and choose a higher refresh rate from the list.

Does it do it more when you're playing a game?

Yes, it does it when i move screen up and down.

it doesn't seem random because i have just been moving it in a game, on desktop and on internet and it stayed on throughout.

The video cable runs through the hinge. The video cable runs through the hinge and can get worn.

It can have a break, crack in one of the traces that loses conectivity somethimes and causes the screen to lose the signal.Yours appears to need replacement.
