Urgent: MacBook Pro 2019 won't turn on - No Power

Hi everyone,

I'm having a big problem with my MacBook Pro i9 2019 15", and I really need your help. I got this MacBook in September 2019, and everything was great. But after I updated it to Big Sur 11.1 in November 2020, things got bad.

The problem started with random restarts, but I managed to fix it temporarily with SMC and PRAM resets.

Now, things have taken a turn for the worse. When I power on my MacBook Pro, the fans start, and the trackpad clicks, but there's no display or lights. After a few minutes, it restarts on its own.

I've tried SMC and PRAM resets over and over, but they're not working anymore. I visited a local repair shop, and they think it might be the processor or graphics card causing the trouble. I believe there's a solution out there and I'm hoping someone here can help.

I rely on my MacBook Pro for everything, so finding a fix would be a lifesaver. If you've experienced this or have any suggestions, please share your wisdom.

Many thanks,

Simo
