In other words what kind of connection cord runs between cable box and TV?

Hello !Here's how the TV is connected to the Cable Box:I have a Cable Box, plus a DVD player-recorder, plus my TV...My TV is connected to the ''RF OUT'' in the back of my DVD player-recorder;My DVD player-recorder is connected by its own ''ANT IN'' to the Cable BOX ''TO TV'';Finally, my CABLE is plugged, from my CABLE provider to ''CABLE IN'' in the backof the Cable BOX. That's it !

i can't find the manual for the DVD player. I saw some Magnavox that even with a IN and out coax where only able to output their own signal on the out and used the in only for recording. Try to connect it direct from the cable digital to analog box to the TV. We will see what is next from there.

Also, you have no other cable connected to TV right now other than this coax and the power cable?

I have just tried to connect it direct from the cable digital to analog box, to my 20inches TV.The result is still the same: excellent DVD film reading, but no access to TV.In fact, when my TV is on the Blue background DVD image, I depress the TV/DVD on my remote control, to go to TV,then I see a black DVD screen instead of a TV channel.As you pointed out, I have only the coax cable and the power cable connected in the back of the TV.Jacques Soucy

With you last comment i am no longer sure if you mean that the stand alone DVD work and send picture to the TV or if the DVD player internal to the TV work. Tell me that the one working is the external one and that you can play and see a DVD disc content from it. That would mean that that section of the connection is working and that the TV is on the right 3 or 4 channel to also receive the TV programing.

The cable box send NTSC signal in RF mode and the TV and DVD player are both compatible with it so it should work. In case the TV tuner have a problem, you may try to use the external DVD player as a demodulator and connect it to the TV with composite cable (yellow, red, white) to one of the line input of the TV (L1 or L2)..

I'm sorry Martin, but I tried to connect an external DVD player to my 20inches TV with composite cable (yellow, red andwhite) to one of the Line input of my TV, with no success.

Did you try the INPUT-ZOOM button on the TV remote, this is the button that select the line input at the back of the TV, not the TV/DVD button alone.

Was it in an hotel before? I see no hotel mode on that one but there is an input lock covered at page 28 of the manual (the password ***** is covered at page 26). The TV could also have a hardware problem but i have no way to know this without having the set on my testing bench.

Hello Martin !I really don't know if my Toshiba was in an Hotel before...But I do think that you're getting closer to the solution, with the different LOCKS that seem present on my TV.
Here is what I tried: PARENTAL LOCK: I tried to change that number "8", for number "2", then I wrote a new
password (I don't know the last owner password) "1947", but I failed to change it, because I couldn't avtivate
"OK" on the TV, with "ENTER" on my remote control...
I also tried to unlock "Panel Control", with no success.
Is there "a backdoor password" I could use on my Toshiba TV that could give me access to UNLOCK what
I need to unlock in my Toshiba TV ??? (as we sometimes use to unlock the BIOS in computers)I think you are on the right track, and with your precious help, I am sure you can solve my problem this week.Jacques Soucy

OK, You need to put the TV in "TV mode" i guess that you can do that even if you see nothing. Then press both at the same time "VOLUME DOWN" on the TV and "1" on the remote control for at least 2 sec.

Hi Martin !I tried a couple of times to get to "TV", starting from DVD, with the TV-Video button, and the only thing I can get is aBLACK SCREEN, WITH WHITE LETTERS DVD. Naturally, pressing VOLUME DOWN on the TV, and "1" on the remote for at lleast 2 seconds , produces NOTHING.Jacques Soucy
StHYACINTHEJUNE 28, 2016
TV Technician: Martin, Technician replied 1 year ago

Does the TV start with that black screen and white DVD or do you only get to that state after pressing TV-DVD button? Does pressing that button on the remote doing anything showing that it at least work and have an effect. I just noticed there is a "source" button on the TV itselft, that does nothing either?

Ask Your Own TV Question
TV Technician: Martin, Technician replied 1 year ago

Seem it is only called source in the service manual, it might be the TV/Video button you talk about (it is right of the channels button on the TV).

Ask Your Own TV Question
TV Technician: Martin, Technician replied 1 year ago

Another thing we can do to enter the factory menu:

Press on the remote in order those button: up, down, left, right, menu, enter.

This should bring you a menu on screen (factory menu).

Change the ADDR value from watever it is to "FFF". Then save, then without pressing the power button, remove the AC cable for some sec and connect it back. This should put the TV in the state it was when new.

Ask Your Own TV Question
TV Technician: Martin, Technician replied 1 year ago

I forgot to mention to make sure that once adresse FFF is reached, the DATA need to be made as FF. Also to make the save you have to press enter.

Hi Martin !
First, when I turn on my TV, I get a black screen and white DVD letters, then it switches to the Blue Welcome Screen with the letters DVD again.
Second, there in NO Source button on my TV, but a TV-Video button which is to the right of
the channels buttons..
Third: Trying to enter the Factory Menu: I can enter (no problems), the ADDR was 000; I succeeded
to write 00F... How can I write the two other F, to make it FFF ???? I need your help !

TV Technician: Martin, Technician replied 1 year ago

ALl that should be done with the left/right/up/down on the remote, i guess as i don't have one at hand to test and they are always a bit fuzzy in technical doc about that. Perhaps there is an invisible cursor.

Ask Your Own TV Question
Customer reply replied 1 year ago
Hi Martin !Could you be more precise about changing Datas when entering the Factory Menu ????How do we achieve going from ...one F to FFF... to change the address to get definitely de TV signal ????And what about that INVISIBLE cursor ? Can we make it VISIBLE, and HOW ????Jacques Soucy St-Hyacinthe.July 1, 2016.
TV Technician: Martin, Technician replied 1 year ago

That is the problem, i don't have that information. Usually i get into a service menu and eventually get the hang of it (there is no "standard").

Perhaps you have to change each digit individually or perhaps it need to be incremented (Hex value like that go from 8 to 9 to A to B to... and so on to F (the largest value) before going to 0 to 1 to 2 ... etc.

I don't say there is an invisible cursor, i said there might be one. If you got it from 0 to F you are not far from finding how. I often found that giving the remote to someone else to try often help to find new ways to work around an interface.

TV Technician: Martin, Technician replied 1 year ago

Awesome! I don't know if this is common for this set. For some peculiar problem like that i always advise to write the solution on paper and stick it on the back of the TV (because "la mémoire est une faculté quie oublie").
