the software that tests the MiniTiouner (TestMyMiniTiouner) and the software that tests the drivers and codecs installation (CheclMinitiouneDriversand Filters) are made to be used outside the situation where you are receiving a DATV signal. Many things must nbe checked before the last step : recive a signal.what seems strange is that in these tests there is no one with the circuit in operation and a DATV signal at the input of the tuner, which identifies a valid TS
The only thing that these software don't do: they cannot extract and show a TS from a DATV signal because....
If I develop a test to do "with the circuit in operation and a DATV signal at the input" I will have to offer the possbility to change the frequency, to change the Symbol rate, to see the RF signal to be sure that you are receiveing something, to also add some tools to see if you are locked or not etc..
......
well you just ask for a software like Minitioune.
Minitioune is the last tool to test if your MiniTiouner works well.
I come back to your problem:
- the 2 test software show that your NIM is working well and that your computer has the good codecs installed.
The only thing that these software cannot tell you: the TS effectively received is well transmitted to your PC via USB.
Using Minitioune:
as your NIM can lock and all leds are green in Minitioune that means that the TS is well extracted by the demodulator chip.
After that it goes to the output pins of the NIM, goes from the input on the PCB to the FT2232H, with a valid signal sent by the 74HC10
So, using an oscilloscope you should see signals on the 8 TS data pins (CN3-BD0..BD7) and Pin CN3-14
But perhaps you don’t need to check that
You say : « If I connect the "AutoPid", after a few seconds it automatically disconnects and goes to "PID from INI”,
1. If “few seconds” is 2 or 3 sec that means that Minitioune has found the video and audio PIDs
2. If few second is 15 sec that means that Minitioune stops to search because it cannot find any DVB tables in the TS because they don’t exist or because the TS bytes are badly received and data are unreadable
If the audio PID and video PID are found that means that you have no hardware issue. Just look at the values indicated in the audio PID and video PID boxes or click on “info checkbox’, you will see the result
If you get the 2 PID values, you don’t have to use an oscilloscope, all the hardware works well
If in the info page you see the PID scan going from 0 to 15 with the indication “no PAT”, you are in the second situation, the TS is bad.
Now you have to know why it is bad,
- are you sure of the TS transmitted, can you receive it with another tool (Tutioune3200 or Tutioune1600 or …)? If yes, that means the TS received has been damaged somewhere by the hardware.
So you need to checkwith an oscilloscope all signal I have indicated.
Remark : when you record the TS, you say that VLC cannot show the video when you play it, so I suppose that the TS bytes are bad and that Minitioune has no found any PID and “autoPID” button has stopped after 15 sec.
If you record 5sec of TS and send me the file, I could analyze it and tell you if the trouble is on bit 4 or 5 on each byte, so you know which pin to check and do a point of solder ….?
