It's been 2 and half years I got this tv. When we are getting lines on tv when it's having warranty servicing guys used to come and check. They told it's problem with cable not with tv. Now after expire of warranty they observed everything keen and now they are telling some ants went into the screen so these lines are appearing and it 'll cost rs[protected]. What should I do now.
