Best Place to Go for PlayStation 5 Repair

Hello Everyone

This might be a question answered already once, but I could not find anything that was recent at least. I have a PS5 that seems to be having an issue with shutting off on its own mid-gameplay. I have done some troubleshooting on my own to fix it, and this has not bore fruit, I predict there may be a bigger issue with the hardware.

That being said, what would be the best place to take my PS5 to for a diagnostic/repair so that I would not have to send it out to Sony, cause I sent a PS4 to them and it took months to fix and it ended up breaking again after a month and they wouldnt fix it again. Any and all help I appreciate.
