Hello I have a pair of Sony WH1000M3 they are 3 years old and have stopped working. I returned them to Sony who diagnosed the main board requires replacing. The very unhelpful Sony staff are unable to get the part so they can’t repair it so my alternatives are to throw them away or try to find a replacement part and try to repair them myself.
I am after a step by step guide to replace the main board any help would be appreciated
Thank you
