Purple tint on screen

Color splases can show up when the sets are move from one location to another or when they have been dropped while moving it,another reason is when a speaker is placed to close to the tv.The tv has an internal demagnetizer witch gets activated when you turn the tv on,I suggest to unplug the unit for about 15 minutes and then plug the unit and turn it on,If the unit was dropped this problem might not be repairable.I hope the information helps .

Thank you very much it is because of the magnets inside the speakers i had my subwoofers next to my tv and i was pissed cuz the whole left side of my screen was purple tinted then i found this and moved it problem solved

What about the tv's speakers ? can they affect it?

I rekon you have (or have had) a magnetic source like a speaker near the TV. You need to de gause the screen. There is a "de gause" wand that you may be able to hire from somewhere that creates a magnetic field that may reverse the damage, Simply wave the "wand" over the affected area whilst the wand is ON and that may sort it.
