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.

Good point "ikke"
Sud76137 did you check your power supply is it 15V AC or is it 15v DC it should be AC.
