I've fiddled with the Std/CATV switch on the back, the VCR/TV switch
on the front, nothing seems to have an effect. On newer VCR's I've
had, going in to the RCA's is accomplished by selecting "Line" on the
channel selector, but this old Sears doesn't have a "Line" channel,
only 2 - 13.

The RCA in's must be there for a reason, any suggestions as to what I
need to do?


It's probably just one of those non-obvious things.

If it's only going from 2-13, that is sort of a tip off something isn't
right. Even the oldest 1st generation machines had uhf tuners. Since it
seems to use an electronic tuner (digital display) chances are it needs to
be programmed in.

I remember I think it was RCA that used off channels like 97, 98 or 99 for
the aux inputs.

Another possibility is the remote, there were some Zenith/GS ones that the
aux inputs were only selectable on the remote (input select). If you are
missing the remote, is a real possibility.

As you probably figured out, the whole Sears/LXI series was just re-badged
"something else", not sure if they were loyal to one outsource or another.
Seem to remember them using anything underneath, Fisher, Sanyo, RCA,
Samsung.

I'll take a quick look to see if their model number crosses over to
something else but this "problem" is easily solvable by a trip to the local
Salvation Army or local thrift store where you could get a different machine
to do what you want for probably $10 these days.
