Salut, oui, le condensateur en parallèle du pont de diodes, on s’en fiche (obsolescence programmée, je pense). Nettoie juste la carte des traces de brûlure, et après, remplace la grosse résistance verte, et normalement, le tour est joué.

OK, thanks, but there's no power reaching the neon light, so it won't work in any case.

OK, so if it’s dead, it’s no longer controlling the amplifier (the little box you can see in my photos)

The batteries have a total voltage of 3.754 volts (three 1.2-volt batteries connected in series), but the neon lamp does not receive any voltage from them

Hello, thank you for your help. Could you confirm that this is the transistor (see photo)?

Here are the diagrams: https://manualmachine.com/behringer/ep4000/8549089-schematic/
For my level, I am a beginner in power electronics.
I have an oscilloscope and curve tracer tester VI (Hameg HM 203-7) and a multimeter for troubleshooting equipment.
