How can I fix my Samsung LE40R74BDXEU?

Samsung LE40R74BDXEU -DEAD WEIRD PIXEL BANDS BLOCKY

Hi All,

I have an "Samsung LE40R74BDXEU" LCD HDTV; My stand recently broke and I purchased a new swivel stand and fiitted it. A few days later I had noticed that all of a sudden I would get this fault of lots of pixels in bands across the screen. The fault appearS when watching the inbuilt freeview or any other selected mode including HDMI, AV, Etc... The fault appears when you select normal TV, SCART AV, S-VIDEO, HDMI, Red, White, Yellow, HDMI - PS3 or XBOX360 or when you try and access any of the menus; ie: turn volume up and down, EPG, etc...

I have uploaded some photos shown below; taken on my camera phone.
Does anyone have any ideas?
