Hello, I need help. I have a big problem with my AFD100…
Recently by switching on with the auto bias it put in the 4 lamps in default, I switched off it and when i relight always in auto bias and only V1 in default. Further to the advice of a friend I have inverted V1 and V2 and the surprise V2 ignites but V1 remains lit. I have heard a big crackle just before the end of the auto bias.
