Connected Chromecast and 1 month later lost picturee Reconnected Chromecast and 1 hour later lost sound on Samsung TV. Could there be a connection?
It won't damage the TV. Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Thank you Knight. I will keep trying. I have no picture and no sound now, and I found all this a bit overwhelming. When I get the courage, I will try to open the back panel. How do I know if the back light inverter board is damaged? Someone also mentioned that some capacitors or fuses may be blown/burned.
Whatever suggestions you've got, it will be best to replace the defective board as card basis, rather than making surgery to it. In most cases, it will be a failure. I'm doing this kind of work; I mean, service and repair work to all kind of electronic equipment; since 1974; and doing the same till now. From the work experience I've got from these long 43 years, I suggest you to replace as card basis. But, before replace the card, you should detect which board is faulty. That will be a problem, and is the main part of any repair work. You too will admit it.
anyway, try to detect the faulty board. Then determine what to do. What else to say.
