I have given complaint on 7th July15, but have not taken any considerable action from your end so far.
once again i am repeating, I have purchased 9.11.2011 after one 1 1/2 years changed new display screen on 21.03.2013 amount is Rs.11473.00 from sony service (chennai service centre) from chrompet, chennai 44.
Again i got the problem in the screan with in 2 years of replaced march 2013. I registered complaint through sony customer, and one irresponsible technician came from sony service centre (chennai service) West Thambaram, chennai 45. He taken photos and collected Rs 225 and gone, then i got call from service centre he told that display screen to be replace new one cost have to pay Rs 10800.00. I dont want again spend mony for replaceing this type of your low quality product.
