Hey guys, I just wanted to say, i've had the purple banding issue on my PL58C8000 for about three years now, and I thought it was just panel damage. I made no attempt to fix it. However, today I guess I was so pissed off that I decided I would attempt to fix the issue, and if I failed, I would buy a new tv. Well, I found the samsung service buliten and the 3D58 bin file. I got the hex code for the service menu, and plugged it into my LG G3's IR blaster. I updated through the service menu. And now, my TV has been rid of this plague, the screen purple no longer. Thanks to everyone (two years later) who got this process working!
