Address:

600044

Dear sir,
I bought sony led tv klv-32ex330in5 on[protected] from chandra vision (Sony centre), no.1 vedantam street, g. S. T road, tambaram sanitorium, chennai-600047 along with v-guard mini crystal stabilizer. (Invoice no:4657)
On saturday[protected] @ 4 pm suddenly the picture colour becomes grey and showing double images of pictures and letters. Then within 30 minutes i taken to the sony authorized service center, abirami plaza, 17/4 m. K. Reddy st., west tambaram.
They told the display has gone and it will cost rs 11, 000 (Eleven thousand). I am bit surprised and pained about the sony quality. So i would like to know from the responsible sony personnel, is this true and how come the power from stabilizer thru sony supplied power adapter will failure the display screen with in the span of 3 years 8 months, then this is the quality of sony product. I recall my thoughts that, because of top quality and leaders in tv technology only made me to take decision to buy sony tv, now i felt that, is i made a wrong decision.
Pl kindly reply
Regards
