Hello Jean Pierre
OK with the operation and explanations about the ISS mode. Perfectly understood

I am struggling to desolder the NIM from the board, it is not easy, now I am partially desoldering. I am dedicating my free time (I have little) and I do it because I am also interested in knowing what has happened. I'll let you know when I have it ready to send it to you.
I will be pending for when you have the new version 0.8.
Thank you very much Jean Pierre

Hello eveyeone,

I’ve had the same problem message "No video or bad codec / Pid". Tried all software solutions. Good C/N MER of 9dB but no picture or readable TS file.
Measuring the TS2D0..D7 gives data on scope gives 0-3 V to all pins but also data at 1V level on D4 and D5. Measuring between the pins gives 100 Ohm between D4 and D5 pins 30 and 31 on the Serit tuner module.
Problem was a bad soldering connecting two 47Ohm resistors in the module shorting D4 and D5 together.
Working fine now!

Best regards,

Robert PA1RK
