LN46A630M1F Horizontal Lines with Text

[rustytierod]

Hi all,
I found this Samsung A630 in the trash and the picture has the gamma chip problem on the T-con but also some horizontal lines that seem to parallel text.

I believe this may be a defective panel in addition to the gamma chip on the t-con board.

Any thoughts? Thanks in advance.

Please anyone? The lines only follow text making me think that maybe the problem is not the panel.

I think a t-con will solve this,doubt it's the panel.

According to shop jimmy:

"IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen)."

But I guess they mean "permenant" lines, not ones dependent on input.

I'm also confused because there seem to be two t-con boards for this set, a green one and a blue one?

Well,you really don't have lines in the way they mean.It looks more like a imperfect driven screen. The gamble will be : Is it T-con or is it Main board. But seeing the solarisation (is that a word?) of the picture I'm leaning strongly towards a defective t-con.
Just don't send hate mail if it does turn out to be main board.Some more input from the more seasoned ones here perhaps?

Is it possible that there are two t-con boards on this set? Haha, I never get mad like that.

green t-con seems to be for the A530 models? Blue for A630,not sure if they carry different panels?
