Koryo Kle40elbf Television — Picture is blurred and ghosting

Address:

Nagpur, Maharashtra, 441102

Few days ago we received a General Setting Menu having many options right on the top of the screen. We tried to remove it but it was not responding to remote control. I also tried by restarting the tv from power board but nothing worked. After 4-5 hours it was automatically disappeared from the screen leaving behind the picture quality totally messed up, nothing is visible clearly.
We called in customer care Bangalore my 1st surprise None of the support staff did not know about this General Setting Menu and they provided the service center number for Nagpur. I called them and they send their technician to our home. The technician checked the tv opening its console and assured me it is not a big deal he will fix it in next visit and I paid him 750/- for this visit.
I waited for 2-3 days and again called the service center and my 2nd surprise, when they said that your tv panel is defected and they need to replace it and for that I have to pay them 18000/- ( Eighteen Thousand) . Boss...what is this..
It is my humble request to your Koryo company and Futuregroup to please provide authorization to persons having at least common sense.
Thanks for giving worst experience with Koryo.
