Funny Philips motel TV

[electroking]

I recently stayed at a motel that provided TV service with a Philips
CRT set manufactured September, 1997 at a Greeneville, TN plant.
The funny thing wat that this set had no rear (or front) connectors
except the 75-ohm cable input. No audio or video input of any kind.
Cycling through the cable channels with the remote control, I found
an AUX setting at the end of the list, but no way to feed it. Has
anyone else seen such a (relatively) recent set with no auxiliary inputs?

The model number was OCV725 C107, and also a chassis number was
listed: 25B700-7562. Thanks for any comments.
