I hate to bother you again, but, after getting the installation up and running I am having a problem. All the devices (phone, tablet, laptop and pcs) can see and connect to the Jellyfin server. However, the TV which had previously been able to connect, no longer can do so successfully. When the connection is attempted, the Jellyfin splash screen shows for a few seconds, followed by the rotating circle in the middle of the screen. There after there is a bright flash at the bottom of the TV screen followed by a totally darkened screen except for the time which appears in the upper right hand corner of the screen. The Jellyfin server and the TV are on the same network and the system did work .
Sorry to be such a pest, but I am completely new to Linux.
