I bought the TV second-hand, so I am unsure of how old it is. It was working fine till two days ago but yesterday when I tried connecting my laptop to the TV, there was no audio or video on the TV. There was no shortage in electricity. The LED is illuminated when I switch the TV on, but I cannot connect with any external HDMI connection (Laptop and Firestick). I have tried draining the tv for residual charge but the problem is still there. The MSN number is 30013819. I am sorry for the lack of information in my post. Regards, Sankalpa
