Hello dvbgaj,
welcome to the Polycom Community.
It is always useful to provide some more details like the HDX Serial Number, the HDX Software Versions, Details if this worked before you swapped the screen etc.
I would assume you are using a DVI cable from the HDX to the TV but as you have not provided that detail I can only guess on this.
In addition if you switch between the sources on the TV do you get the sound but no picture from the HDX on any other inputs?
Did you check the TV Manual if the RCA sockets where you plugged you red and white cables into are actually inputs or outputs ?
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
