Sony India — complaint for my sony bravia klv32r482b and sony service issues

I bought my sony bravia klv32r482b on 16/07/2014, within one year of spending my hard earned money (Rs 32227) on the so called quality brand its foc panel got damaged. We have normal usage of tv and also had a branded stabilizer in place for any power variation, still within 1 year i had to call the service center to get my tv repiared. Although it took them few days to come down at my place and as per them "replace" the foc panel. Since it was within 1 year luckily, i had been told to only pay rs 1200 as service fee and foc was covered under warranty.
Till next year or so, it seemed to run fine, but after sometime again some glitches were seen on screen and now last month tv has completely stopped working. We called the service center again. After 1 week a guy came checked it out and told its a foc panel issue again. He told service center would call regarding this and took his service fee and went.
We only had to track the status for the same, and finally got to know from service center that foc has to be replaced and we have to pay rs 13000.
Year by year if i have to replace panel, what quality does sony provide to its consumers.
We have shown a local tv repair guy to double check the issue, and he has suggested that first time possibly the panel was not replaced and was just repaired temporarily.
What kind of transparency does the service center keep if the above is true.
Its good that small brands are coming up as competition to these big gaints, sadly when i bought tv those were not available.

Attached is the tv bill and two times service bills.
