I have purchased a tv of above description on 09 april 2017 and installed on 12 april 2017. Same tv was working till 15th oct 2018 3-35 pm. On that day around the same time explained above tv picture disappeared.
We have put up and a service representative called and checked the same. We received a quote of total sum of rs: 37, 0406/- for the above repair. We were astonished to see the kind cost for the repair of the tv, this tv has just been in use just 18 months and 03 days. We need to shell out such huge sum of money to recover the tv unit back service. I think its a very high cost comparing to the useful life of the tv set i have been able to get. My request is that you may kindly evaluate the useful service and its cost of recovery back to service and according to me is in no way justified.
Please do look at it and provide a reasonable price of recovery and carry out necessary repair at the earliest.
