Cable TV

Cable signal may be a little low.

Do you have a distribution panel the all the inputs go to? Could be that the selector buttons were disturbed and not allowing the signal to go to the other sets. Otherwise you may have a bad connection somewhere is the cable distribution system.

When you do a channel scan on back TV, what kind of cable does it search for? If it is not set on auto, do that and re scan.

Maybe the front TV scans for both analog and digital and as said above, the rear TV doesn't. Like MaverickBBD said check and or fix that.

Some parks have digital cable and others have analog.

When all your TVs receive cable, my guess is that the park has analog.

When some of your TVs don't receive, the park has digital cable & the TVs that don't receive do not have QAM (ie, digital) tuners.

There are now 4 different major types of cable and a few secondary

The major
NTSC: This is the old Analog Television, once all systems were like this
QAM (With sub settings) This is regular Digital Cable.. NOT ALL TELEVISIONS have a QAM decoder.. In fact the one brand that is still made (Actually once again made in the USA) does not decode QAM..

NTSC.. Some cable systems. like the one I'm on, Simply pass on the signal they get from Over the Air locals.. Do not change it to QAM as many others do.


ENCRYPTED: you need a "Set Top Box" for these, no matter your TV.

I have 3 TV's here too. one, when set to cable, does all 3 of the non-encrypted formats, QAM, ATSC and NTSC.. One only does NTSC and ATSC when on "Antenna" and QAM (or NTSC) on Cable (Will not display the digital channels on the local cable) the other two do all 3 when on cable ATSC, NTSC and Qam.

Very confusing.. thankfully I figured 'em out.
