Gamecube short circuit without any connections?

[SpecialHam]

So I was literally done with my GCp and I had just put it together, but oooops, I forgot to tweak the pot on the DD so I can play burnt dvds. After i tweaked it I did a test run and it shorted out.

After that I simply could not get rid of the short circuit so I de-soldered every single connection leaving the motherboard bare.

My multimeter reads about 32 Ohm between the 3.3v 5v and GND.

-No pins are touching.
-Cleaned everything with acetone.
-Trimmed the edges and sanded them to prevent the layers to make contact.
(trimmed after short circuit to check if that would help)

I simply do not understand what the problem is. I was finally done with the portable and now its
screwed up.

Any kind of tips or troubleshooting suggestions would be greatly appreciated.

32 ohms between 3.3v and 5v doesn't sound like a short to me. It sounds more like normal resistance due to certain components in the system, but you did say you desoldered everything. Are you sure no voltages are shorted to GND?

My other cubes measure 1.7k between the two lines.
I am sure nothing is connecting to ground.

maybe something got stuck under the cpu/gpu? There is a tiny gap for something to get under there.

Try sandind the edges of your motherboard.

Believe me I have done that qn checked everything with a microscope to se if the layers are touching

I don't believe 3.3v or 5v is accessible underneath the GPU/CPU so that's not likely.

32 ohms still sounds more like some low resistance caused by low-resistance capacitors to me, which some motherboards have and others don't. I'm more inclined to think you have another problem but I'm not sure what that would be.

Sorry, let me correct myself. The 1.9 and 3.3v line was shorting out.

I heated the gpu and cpu with a hot air gun and I accidentaly touched it while the solder was still melted and pushed the gpu off its slot. Ohm reader says 0 ohms now

I did find a super thin hair of copper under the gpu. I hope that was the issue.

I guess this is where I learn how to do BGA work
