Hello all - I recently moved & the power down cost me my settings on an MX 5000 TV for which I long ago lost the manual.
 
Despite trying what seems like every conceivable combination - I can't get it to find the source which is a DirectTV box.  It's connected both via RCA to audio R/L & vido + S video in.  That's the same way it was connected a few weeks ago at my old house where it worked fine.
 
Any suggestions?
 
Right now I'm set to:
Device setup Device: 1, Output chanel 3, Connection: This TV input A.
Connections: Setup code: 1
TV input A: CATV std
