Hello,
Resurrecting an old post here, as I have a TV that's doing the same thing. However, I've had no luck with getting it out of this mode.
I have a UN58MU6071FXZA that was given to me because they couldn't get it to stop flashing red, blue, green on the screen. I have no idea how it got into this mode, but I highly doubt the person that gave it to me knows anything about service menus or anything technical.
So, I built an Arduino IR transmitter to throw the Factory code at it (and also tried other sequences) but it doesn't kick it out of this mode.
I did notice that the screen colors would dim ever so slightly when the "Info > Factory > 3speed" sequence was sent, almost as if there was something coming up under the solid colors.
Does this sound like a hardware issue at this point?
Thanks for any help.
