Defect in Panel & Motherboard of SONY TV in 11 & 22 months of purchase respectively

Deficiency in service
Request for refund
Please allow me bring to your kind attention harassment, mental agony caused by supplying reconditioned defective TV - under warranty up to July 2012 and indifferent, careless, callous, evasive attitude of SONY service team towards its customers.

I purchased a SONY TV. It had defective BG2BOARD . After protracted follow-up, Sony India replaced defective TV and vide Bill No.11154409 dated 12.5.11 charged Rs.23, 632 towards repair/replacement of defective LCD.
At the time of installation itself, TV supplied by SONY vide Bill No.11154409 dated 12.5.11, it was brought to the notice of technician that there is problem in sound output. SONY INDIA. reacted that ' Itni Problem Nahin Hai' There is not much of problem. In other manner they agreed that there is problem in sound output. We were not reconciled why a new LED TV should have any problem with sound output.
We also requested SONY INDIA to please check the problem and incase TV set had some defect to replace it. There was no response from SONY.
However, instead of flaring up the matter, we consoled ourselves and reconciled with the quality of voice.
Subsequently, Newpaper reports appeared about defect in LCD TVs supplied by Sony.It seems there is manufacturing defect in all the TVs supplied by SONY. But Sony instead of accepting the defect is indulging in denial and charging/fleecing its customers towards exorbitant repair charges.
TV supplied by SONY developed same problem as that was in the old TV. Complaint complaint no.9552285 Dated 4.3.2012. followed by letter 5th March, 2012 was made. Service engineer advised that B- Board needs replacement. SONY informed that it will be repaired.
Not satisfied with repairs to a brand new TV which is giving trouble, May I request you to please intervene and take necessary action on priority to take back defective TV and refund Rs. 91, 632 at the earliest.
