Performed Trace Repair on a P104-100 GPU

Hello, this is Munou.

I had given up on the P104-100 about twice, including the other day, but the repair is now complete.

The reason it still wasn't working

Simply put, the parts I thought were connected were actually disconnected. The following content is messy, so please skip if you're sensitive.

※I properly cleaned it with ethanol afterwards.

Using a multimeter, I performed a continuity test and confirmed that the 6 wires that were definitely disconnected were now connected.
After that, I found the remaining two suspicious wires, scraped the board, and jumpered them.

And then...

Oh!?!?!?!?!!

IT'S HERE!!!

It's working successfully!

However, the fan is constantly at 100%, so the fan controller also seems to be damaged.
It's probably a product from a factory that was washed away in the floods that occurred in China around last year, so it can't be helped.

Wow, I did it!

Since the fan controller can't be helped, I'll just use it as is.

Well then.
Until next time.
