LG Electronics — Denying Warranty for a TV repair

Hi, I along with my Brother in law purchased an LG 42inch lb6500 model TV on 21st March and got the Installation and Demo done on 23rd March. The TV has been working fine until 29th march when suddenly out of no where 1/4th of the screen went blank with white screen. We initialized a Customer service request complaining on the non functionality of the TV screen and a Technician came on Tuesday (31st March) and said the repair costs 20k+ and warrant won't cover this issue. We are Baffled with the response as the TV is barely 1 week old and the issue happened out of no where! How come we are hold Responsible for a faulty TV which is Brand New and also when it has 2 years of Warranty? The TV is practically scratch less to even say any physical damage has been dealt on it and the Issue happened in front of our eyes when we are watching the TV out of no where! I'm amazed at the guts of the Technician to say these lies on our face and trying to RIP off people's money. I'm seriously disappointed with the LG customer service and this little scam they are running denying warranty every time citing users fault when nothing such is visible. One thing for sure is that LG customer service is pathetic and they are selling faulty devices charging additional money when the faults were uncovered. The Warranty turned out to be a joke as at the end nothing will cover by warranty and everything is physical damage even when the TV is lying there untouched working fine just few minutes earlier thus no warranty. These ill practices by LG should be made aware to public so that other buyers will stay away from LG products. Thanks Ganesh [protected]
