Question about Samsung LN-T4661F 46 in. LCD HDTV
Hi. First time ever, I dozed off early morning, woke up and the HD tv I was watching had a good bottom pic but the top half was a diagonally lined bright orange color!
I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

This sound likes the incoming signal is week. You should play a DVD player to see if the problem stays same or not.
If you try all sources ie HDMI, AV Component, etc...the TV show the same problem. There are two possibilites: T-Con board or main board need replacing. You should need technician to figure out the problem. Hope it help.
