Everything from Channel 14 and up won't reset

If you have just an air antenna and your tv is set for cable and not air, you will not pickup any channels past 13.

I get channel until #13 how does i get the other chnnel

TV's of this era have two modes that the tuner can work in. One is the AIR mode and the other is CABLE. In the air mode the tuner picks up only "off air" frequencies,... and up to channel 13 they happen to be the same as cable channels 2 thru 13. If you are using cable you will need to go into your on screen menu and find where to change the tuner from "air" to "cable" to get channels above 13. Older sets had a switch on the front and sometimes the back to select the tuner mode.

I can't program channels above 13

Check your TV settings and be sure to set the tuning mode to cable (sometimes it says CATV). You will find it's set to "air" now. When set for off-the-air tuning, cable channels 2 through 13 work fine, but above that you get nothing. After you set your tuning mode to cable, rescan channels and ou should have everything.

I am trying to get channels above 13. I do not

Try bringing up the menu by holding both volume buttons down at the same time (or use menu button on remote if you have it). Go into CH SET using the channel and volume buttons on the front of set (or use the SET + and - and the ENTER buttons on remote). Go to the TV CATV line and move the arrow to CATV. Let menu time out. This will put tv into cable mode. Hope this helps.

Zenith tv model #A32B41W

You probably need to get into the Menu > Tuner Setup and set it for "Cable" instead of "Off Air".

Hope that helps...

No uhf with antannae

UHF channels are basically "line of sight" type signals. You need to be pretty near those UHF stations.
You need a Uhf or combination Uhf/ Vhf antenna to receive them - - Usually an out-door type.
Your TV needs to be set in the "antenna" mode to tune beyond channel 13 "air type" channels. Channel 14 is the first UHF channel if you're in the antenna mode. If you're in the "Cable" mode then channel 14 is a cable channel which is operating at a different frequency from UHF.
I hope this will help you!

Reception of vhf/uhf channels

You did not mention which set you have, so look for a small switch (usually on the back of the set) or go into the menu and set the TV to the "broadcast" or "tv" mode. If the set is in the "cable" mode, you will not get any UHF channels above 13.
