plasma blue line

[sapper]

My 42" Panasonic Plasma has a blue line right down the middle.
The screen is a write off, but John Lewis has agreed to replace it, TV that is,problem my old one is 14 months old, and I have to pick one from what they now advertise.
Not sure what to go for a 46 with built in freesat ? or what.
Can someone tell me please why the 46" Panasonic model is approx £50 dearr than a 50" one
Many thanks
