media player flickering screen

i have a media player that plays media through sd cards and drives. When i plug it in the tv the screen starts flickering. I can see the display and everything is fine on the screen but the screen is flickering. What can i do to fix this. I was told its ntsc. im in north america

you just plug in the player with av cables to your tv there isn't anything to adjust the screen with

 

This may sound to simple but if the power plug is not polarity protected with on large pin and one small just unplug it and reverse the plug. It will change the Hertz sync between the two units and should stop the flicker.

 

no i turned the power plug the other way but it didnt work still flickering. It's a nbox player

this isn't about computer screens its about tv screens. i plugged a media player to my tv screen and its flickering

 

First paragraph here - get the idea? Who'd you buy it from?

 

this has nothing to do with computers. Its a media player similar to a dvd player but you dont put dvd's in there to play them. You put sd cards or flash drives and it plays the media thats in them. It has nothing to do with connecting your computer. The computer isn't involved into anything
