Re: Samsung LN46A550 gamma question
The TV is *finally* in its final resting place
My son took the 46" 3D LED that I picked up for $80 and only needed a firmware update, so this one went in the game room.

Re: Samsung LN46A550 gamma question
Holy cow!
BTW, if you start hearing squealing sound from the speakers or the TV start cycling on and off, then you need to change C102 on the main board.Last edited by budm; 02-06-2015, 08:04 PM.Never stop learning

Re: Samsung LN46A550 gamma question
Great to know. I haven't had that issue on any of my Samsungs, but I'll file it away in case it comes up!Comment

Re: Samsung LN46A550 gamma question
Can't swing a dead cat around the Dallas area without hitting a Samsung with a bad t-con gamma IC. In fact, I picked up another one of the exact same model as this one (which started this thread) to have a matching set in my game room. Graph below.
The TV that started this thread is on the left side (image above), the TV that started this thread is on the right side now (pic above was taken before I hung it). But they're noticeably different in person, so having this matched set will make me happy.Attached FilesComment
