LG Electronics — issue raised reg. lg led 109cm 43lj617t on 07/05/2018 is still pending

I have purchased a television (Lg led 109cm 43lj617t) from croma on 05/10/2017 having invoice number sla[protected] with three year warranty (One year with product & two year extended warranty)

I noticed display problem in my tv on 07/05/2018 when i switched it on.
I would like to bring to kind attention also that it was working fine when i switched it off on 06/05/2018 night.
To get resolve the issue, i raise request on 07/05/2018.
An service engineer (Mr. Shiv rawat) had visited to my residence on 10/05/2018 & he took some photographs of tv & went back. I came to know in the evening that screen of tv is internally broken
. I would like to bring it to your kind attention that three persons from lg service centres (Mr. Shiv rawat, mr. Himnshu & mr. Nanak chand) have visited to check defective led panel & they did not find any external damage on tv screen and they were not able to tell exact reason how a led can break internally.
It was completely shocking to me because there was no issue at the time of switched tv off. It was working absolutely in good condition at the time of switched off.
I also talked to his senior mr. Nanak chand (Boss of service engineer) on his mobile-[protected] to understand what the problem was but was unable to get any reason as to how a tv cab break internally. I also contact area service manager mr. Dheeraj srivastava on his mobile number [protected].

I have been asked to get panel changed on chargable basis for an amount of rs. 19500/-. I would like to bring it to your kind attention that this is not a case of mishandling of product as there is no external mark on tv screen.

It is completely beyond my understanding why should i pay for internal damage/broken of panel. It is the clear case of defective led tv, which should covered under warranty.

I would request you to get my led tv panel changed free of cost as early as possible. (Photo of led is attached for your reference)
