Unhappy Green Horizontal Lines Samsung TV

Hello,
a weird thing happened yesterday with my Samsung LE40A536T1F LCD TV.
As I connected it to my PC via HDMI, a green horizontal line appeared on the screen.
OK, I thought, the matrix of the TV is gone. But it doesn't seem to be, as those green buggy pixels only appear when there is some kind of input signal. When there is no signal - no green lines. And if I turn the TV's menu, the menu stays ABOVE the green lines.
Tried changing the source to AV, IPTV, HDMI... again, when there is some kind of source, the lines appear. They also change their position and size according to the input resolution.
I attached some pictures I just took for reference.

Any help will be greatly appreciated.

Broken flat cable. I had this with Toshiba some years ago. Something has messed the contacts, maybe moisture or poor soldering material. Could be something else of course. I think is not worth repairing but of course if you have warranty.

A little update:

I tried connecting the IPTV (set top box device) not through the AV cable, but through HDMI cable - and the green lines disappeared.
Then I got excited and connected my PC again through the same cable - the green lines were still there.

So, if I put the HDMI in the set top box - no green lines (no idea about the resolution).
PC - green lines (resolution is 1920x1080)

My guess is bad RAM on the main board or if this TV has an FRC (100Hz etc.) then maybe something related to that.
