I checked what flatscreen I had and it was a Samsung. With any luck its got the same problem as yours.
So it could be a 'Zero $ fix'.

Mines a Samsung model LA46N81B
Model code LA46N81BX/RAD
Type TU46SO

There will be differences between our flatscreens. We use 240 AC @ 50hz
and I think theres a different amount of lines in the picture too.
There could be a difference in the way the TV picks up recption, ie mines probably set up to pick up the signal from a ordanary ariel rather than a digital sat dish.

So, the actual design of the screen and connections might be the same. Even if theres a different size screen.



So, start the TV up and grasp the top right corner about two hand widths in from the end of the screen and squeeze firmly but not too much or the screen may crack.
If this helps its a hour and a bit to fix it using foam door seal tape.
