Hi everyone!
In the final stretch of a portable build, but not able to get this ps2 advanced trim to boot. All voltages read as they should on my multimeter - no shorts between each other, or ground. 5v line reads continuity to the AV chip.
Is there any other relocations / things that I'm missing that anyone can notice?

wire colors:
red=5v
white=2.5v
yellow=1.25v
blue=1.75v
green=3.5v

Thanks in advance!!

Waaaaiiit just realized I needed to connect all the floating voltage areas together as well (thought they were just alternate solder points lol, my badddd). Still no luck booting though :(

Try connecting 3.5v to the pad circled here:

You sir, truly are a legend!
That did it, thank you!!

I thought that was just a 79001 and similar thing due to the pic in the trim guide. Damn ps2 and it's dozens of board revisions :facepalm:
 
The PS2 trimming guides voltage section can be a little confusing, and even i ran into a similar issue the first time around, but im glad I could help!
