My tv is a funny colour. Mainly pink and green

@ashlee , Ashlee, it is possible the TCON connector needs reseated/connected better. There are other things that could also cause the issue but this is the easiest to check. With the limited info. provided I will post a video showing how to check and reconnect the TCON cable inside a Samsung TV(may differ from your model) but hopefully close enough so you can access and try. Always unplug TV from power 30 min’s before working on it. You could also do a google search for your model. If not comfortable working on electronics have a good repair Tech. have a look, diagnose and estimate repair. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. https://www.youtube.com/watch?v=ZtyhKHDw
