Sony India — vertical lines on tv

Really not satisfied with sony television products. Been a sony customer for quite sometime, the quality of their tv has substantially deteriorated. With my first tv, had a problem with vertical lines and it was oow. Sony said it’s a know problem and asked me to pay for the panel. However, the panel wasn’t available. So they took the back the old tv and i paid addtional and got a new tv.
Within 2 months the new tv failed to power on. The technician check and replace a circuit board. Now exactly the warrant expires on 3rd june and the again the same old vertical lines issue on the new one. Every sony tv has the same problem. Now they are asking me to pay for the service. Never looking to go with sony products in future.
