I have a 2018 Toshiba flatscreen with a model # 43LF621U19. It could turn on before I went to work and when I came back it wouldn’t even power up. No running noise from the fans and nothing from the power light. When I dismounted it from the wall there was a distinctive smell of burnt plastic but taking the shell off (23 screws later) I saw nothing melted or smoking on either boards. I checked continuity (the only thing I’m capable of) and there was the correct amount of voltage running into the main board, but couldn’t get readings from anything else. I then found what must have been burning, a small plastic spool with a thin copper wire wrapped around it, plastic melted where it had contacted the wire. Any thoughts or assistance? If I can I’d rather not have to buy a new television.
