Plasma tv is down. Trying to connect an older Panasonic to

Customer Question

Plasma tv is down. Trying to connect an older Panasonic to the cable box. Can't get it to program the channels.
JA: Just to clarify, what's the plasma television's exact make and model?
Customer: The plasma is out so not trying to connect that. The older tv I am trying to connect is Panasonic PV - M2789
JA: What troubleshooting have you tried?
Customer: Just made certain cable box is connected and on. Tv comes on and then directs me to set the channels. it runs through the channels and at the end tells me that my cable connection is not good and asks me to check it.
JA: The TV expert can solve this for you. Anything else you want him to know before I connect you two?
Customer: I think that is it for now.

Perhaps I can help you with this problem , a few questions coming up and please note that it may take a few minutes between replies;

Expert:  Jack replied 4 months ago.

What type of cables /connection do you have between the cable box and tv ?

Is it coaxial in the tv`s antenna terminal or color coded component cables ?

Customer: replied 4 months ago.
Coaxial from tv to cable box
Customer: replied 4 months ago.
The round, screw on type.
Expert:  Jack replied 4 months ago.

O.k then your tv should be either on channel 3 or 4

Can you try to manually set it there if you have the tv`s remote ?

Customer: replied 4 months ago.
Tv remote is not working either
Expert:  Jack replied 4 months ago.

enter the digts 03 or 04 and see what you get

Expert:  Jack replied 4 months ago.

We cross posted

You still managed to go through the channel scan without the remote ?

Expert:  Jack replied 4 months ago.

Do you have a composite red/white/yellow cable handy ?

Or any rca cable for that matter

Customer: replied 4 months ago.
Up arrow on the tv as it directed.
Expert:  Jack replied 4 months ago.

It should have found the correct channel and locked on it

If you press channel up or down now , does it go anywhere ?

Expert:  Jack replied 4 months ago.

When you went in the menu , did you select CABLE BOX SETUP or AUTO SET ?

Customer: replied 4 months ago.
up runs through the channel set up. Down doesn't do anything. When first turned on it said channel 3 but it will not let me changed the channel
Customer: replied 4 months ago.
Don't have menu access on remote or tv. Remote doesn't work.
Expert:  Jack replied 4 months ago.

The cable box setup option will let you select channel 3 or 4

Just saw your last reply and I think your TV's tuner may be defective , go back in the menu and select cable box setup and choose channel 4 , we already know channel 3 doesn`t work

Expert:  Jack replied 4 months ago.

What do you mean you don`t have access , you told me you ran the channel scan

Customer: replied 4 months ago.
The tv is directing me to do this. It says if you use a cable box, tune it to your local pbs ch, then push channel up. Pushing channel up to get to 21 pbs takes it right into the channel setup.
Customer: replied 4 months ago.
It runs through channel set up and then tells me Cable box is not connectec
Expert:  Jack replied 4 months ago.

I see ,

Right now the way I see it you either have a bad coaxial cable or the TV's own tuner is defective and for a tv that age that would not surprise me , certainly looks like it now.

Your other option would be to use the audio /video input at the rear but you need to change the input and there are no such button on the tv itself so you need a remote here , even if it is a cheap $10 remote , you need one to go any further , no way around that now

Expert:  Jack replied 4 months ago.

You can get a cheap universal remote at places like Walmart , bestbuy etc.

Ok. Thanks for your help. We tried.
Expert:  Jack replied 4 months ago.

goodbye

Expert:  Jack replied 4 months ago.

By the way , just though of something ;

If you press channel down below channel 2 , does it go to video mode ?
