Green patches on screen!?

Question

On my TV (Techwood 37722HD) there are green patches on screen where there is a contrast of colours (bright colours with dark colours) and i need to know if there is a solution,

Someone said try turning off black stretch, but how do you do that?

Answer 1

Your problem may be that you have speakers sitting too close to the TV and those speakers have strong magnets in them that screws up the image with green patches and psychedelic colors.  Try moving your speakers further away from the TV, till you don't get those weird colors anymore.  Most speakers nowadays are magnetically shielded but there are still some that are not.

This also goes for the subwoofer which most are not shielded and they have the largest magnets in them.
