I own a 67" Samsung HL67A750, 1080p LED LCD projection TV. It has been great aside from two issues:
1.) one of my HDMI ports looks like the old scrambled cable channels, all fuzzy and crappy and distinctly green. I don't really care too much. Swapping an HDMI cable isn't going to kill me.
2.) The real problem: The screen appears to do this flickering thing when using HDMI (read: all the time. TV/PS3/PC are all HDMI). Like picture a nice bright vivid picture, and then imagine the entire screen at once going duller, more yellow, less vivid. It stays that way for a few seconds then goes back. This happens off and on and I don't know what to do about it.
The TV is out of warranty unfortunately. Is there any chance this could be a setting in the TV somewhere or a firmware issue?
Any help you could provide would be great, I feel like this has rendered the TV near unwatchable.

Sounds like your main input board is bad. It is not the main board... the service manual shows it is a separate PCB that can be replaced fairly easily.
I donno the cost of replacement, but it should be decent over a mother board.
