LG Electronics — It has stopped working after 4 years of explotation

I purchased the above 32" ledplus cinema 3d smart tv in 2012 and hardly used it for 4 years in the last 8 years. It has stopped working and i booked a complaint with the lg authorized service centre. A technician came and inspected and said the motherboard is gone and lg has stopped the model and spare support is also stopped after 5 years. I had coughed up rs.48, 300/- for the purchase and now he says it has to be scrapped. So pathetic that lg does not provide spare support after 5 years. Had i known this, i would not have purchased it in the first place. I want a solution.
