Andy Watson:
I only have the probes to monitor two lines simultaneously, however, the signals look clean, 0-5V.

Yoanndlc:
Thanks you very much.

Sorry for the delay, I was waiting for the capacitors.
I changed all the chemical capacitors and I still have the trouble.
I am very far Andy to have a clean signal like you.

I took two screenshots, one with triangular shape is Q3 yellow and Q2 pink when I am on FREQ A function
The second is the same but I am in CHECK Function.

Yoanndlc:
Pictures

Yoanndlc:
The signal have got on the bus between ic19 and ic22 is not looking good too

Andy Watson:
As a sanity check - I would  check the power supply voltage on the actual pins of IC39 and IC19.
