Where can I find a Logic Board so my authorized service provider can fix my machine?

Urgently Seeking MacBook Pro Logic Board Replacement

My MacBook Pro Logic Board, like many others, has failed. Thankfully, I have an extended AppleCare+.

However, the i-Care authorized dealer in Chiang Mai informs me that they won't receive a replacement from the Singapore factory for at least another month (I've already waited 3 weeks).

I'm a teacher's assistant from the US, living in Thailand on a tight budget, so buying a new laptop isn't an option. It's frustrating to think a 2 ½ year old, $3000 computer doesn't have readily available parts. Are they in such high demand due to widespread failures?

I'm reaching out for guidance. Is there anyone beyond customer service I can speak to? Local repair shops offer solutions, but I'm wary of voiding my warranty.

If anyone has a lead on a logic board, it would be greatly appreciated. The specifications are universal, so the laptop's purchase location (US) shouldn't be a hindrance. I'm even willing to cover shipping costs to get it to the i-Care store in Chiang Mai.

Thank you in advance for any help!
