    Check IC5 if it is soldered properly and also check diode orientation as well. IC5 is a 7915 negative voltage regulator. Start with that.

    The Diode orientation works alright like you can see on the board. And the Diodes are working like they Seouls. How can i check the ic5 or do I need a new one? Thanks for answering

    Probably using a DC wall wart. You need one with an AC output.
