In the Service Menu there are the following options:
RS 232 Jack (I have used the Debug option)
Serial Log ON/OFF (I used ON)
Watchdog (I chose OFF)
USB Serial (I chose ON)

What is this "USB Serial" for ?

After receiving by new USB to TTL adapter I tried again with both of my TV-monitors (B300 and T24E390), but with the same results.
B300 ..........success using Putty.
T24E390......No output.

So it's not the cable or the adapter. Any ideas? Is it possible the serial to be the 3.5mm that is above the Common Interface, although it is clearly marked with the sign of headphones?

Finally SUCCESS !!!!!!!!
It turns out that the Ex Link port is the headphones jack (3.5 mm) above the CI.
Now I have to find the codes for the TDM. My TV-monitor has a sticker at back with the date March 2016.Any suggestion about the possible codes? (I have already tried some but no result).

Well, try all codes listed on wiki. You might be lucky

If no luck, it's 2015 model with 2014 hw so unlock code is likely to start by 2014 or 2015.
You can "bruteforce" by pasting result of:

Code: Select all

seq -s' ' 20140000 20159999
into console window (or even redirect output to serial, e.g. >/dev/ttyS0) then unlock code will be "first number shown minus 1" :)

But don't expect much of TDM imho, it's a long time there's no more than info into it.

If somebody wants to try that method on M/Q (2017xxxx), we could fill wiki ;)

Thank you @zoelechat for your help, but I am sorry that I cannot exactly understand how to "run" the code you wrote above. Just paste it to putty? Run it from a windows terminal ? ("seq" is not recognised as a command).

By using TDM I hope to be able to make permanent the choice of "ext wifi" in "Network" option. I can do that in the Extended Service Menu but it reverts back to "None" as soon as I turn off my TV. I intend also to enable DLNA as I already have done in my B300 TV using TDM.

From linux terminal of course :)
Here is it as text file, try to copy/paste whole content into Putty window.

@zoelechat Thank you again for your instructions. Without your help I was not going to discover the code for unlocking the terminal (as the required code was not in wiki).
I first tried by using a live unix session (xubuntu) from usb stick. Since I had some errors due to writing permissions in Putty, I decided to go back to windows and use the text file you provided (of cource I was also able to reproduce the same text file in linux).
By copy/paste the values of the text file in Putty, it started showing numbers after 20148146. As you correctly have stated the actual unlocking code was -1 therefore 20148145.
Now I have to find if it is possible to enable ext-wifi and DLNA from TDM.

Top Debug Menu.txt
This is the Top Debug Menu. Any clue as to where Network (ext-wifi) and DLNA might be?
