Nintendo Switch V1 - Crash with buzzing sound, display artifacts, and Hekate boot failure

Hello,

I have a V1 Nintendo Switch that’s experiencing a hardware-related issue causing the system to crash. The most common symptoms are: a total system freeze, a white screen and a very loud buzzing noise from the speakers.

In addition, I occasionally observe graphical artifacts spread across the entire display, even in Hekate, as shown in the image above:

Interestingly, under certain conditions, the console fails to boot into Hekate, despite a properly prepared microSD card being inserted. Instead, I receive the following message:

Missing LP0 (sleep) lib!
Missing Minerva lib!
Update bootloader folder!
Press any key...

After a few restarts Hekate eventually boots as normal.

I’ve read that such behavior might indicate issues with the SoC or RAM. I’d like to ask whether anyone has encountered similar issues.

I ran MemTesterNX and completed three full loops with no errors detected:

Thanks in advance!
