For sale are the speakers from a new TCL 75S451 Roku TV that arrived with a cracked screen. Although the TV had no display, I did hear the Roku chime when powering the TV off, which indicated to me that the speakers worked. I would have been very surprised if the speakers off a brand new TV did not work.
