Anand ,
there are many users on this forum who are using both panny lcd's and plasma's,
this issue is not a common issue as, it does not make sense or logic, why would the tv's stop working after warranty.
There are only 2 to 3 main components in current tvs. the circuit board the power supply and the panel.
Out of which both the power supply and main board can be replaced.
If there is Cracked Screen/Vertical lines or Horizontal Line on screen, then it can be a problem with the panel itself and can't be repaired, the entire panel would need to he changed which would be very expensive.
