Hi Ady,
Welcome to Sony Community!
We're sad to hear that the issue still persist even after replacing some parts. Was there any change that happened prior to the issue? Have you tried to perform some troubleshooting steps before deciding to replace the parts?
You may refer to this link for additional troubleshooting steps, https://us.en.kb.sony.com/app/answers/detail/a_id/35540/p/48903,49902,71396,71419/c/65,66/kw/no%20power
If you already tried the steps in the link above then repair may be needed.
Regards,
Jen
