Solved! PHILLIPS 4K LED image issue

[Connor95]

While my gf was playing pc games on our Phillips 4k TV, then the screen randomly went dim and bright color became distorted. Also now it is retaining previous images on the screen. any permanent fix or clue as to whats going on? Thanks

Try unplugging the set for a hard re-set. Reboots the entire TV.
