LG 42lh3000 faulty t-con? Need some help please. Bit of a strange one.

[dynomo]

LG 42LH3000 . Sounds ok, have picture with no parts missing or lines but its like an infrared image and has a slight rolling going on with the picture. PSU voltages all ok. I have attached pictures.

I thought t-con is faulty? Or maybe main AV board. Strange one.

Any help most appreciated .
