On the 20th of May, Monday, prism delivered our new 77 inch television to our home. On the 25th, Saturday, the television could not be powered on. The repairer from prism 3rd party came and discovered a small 1 cm (we measured) internal ‘crack’ on the left most bottom of the screen, so faint internally that only a torch light can see. Though it is true we mounted the tv ourselves , there was no issues and no bumping and the tv worked fine after that. It could not be powered on on Friday night for the soccer match. They insisted that the tv is totally beyond repair due to that minuscule scratch/crack. They refused to exchange it, nor to repair it and the only offer was to purchase a new tv at 25% off. This tv cost us a bomb $4599. We cannot afford another and we feel that we just donated this amount into their pockets for nothing. The product did not match the durability and quality of our expectation. How can a 1cm internal crack/scratch cause the whole tv to fail? What can i do here? get outside repair?
