This is probably something really simple (or at least that's what I hope). I have just finished my first ever trimmed console of any kind, but unfortunately it wont boot. The board itself doesn't seem to have any damage on it at all, so hopefully my wiring is at to blame here.

semi important information:
- the ps2 seems to be a 79003 model (it didn't have the sticker on the case when I got it)
- I am powering this ps2 with a " CUSTOMLEDMODS Power PS2"
- I am trying to get display out of the original display connector, which I am temporarily leaving on the bard.

Here is what I think it might be:

I can't tell If I am supposed to connect a 5 volt line to this chip here, I think I was supposed to, but I just want to ask before I break something. the only thing that is making me uncertain here is that the picture showing the 5 volts is in the "Standard Voltage Relocation" section, and I'm not sure If I'm supposed to ignore it or not.

If that's not the problem, I have taken some pictures of my wires and where they connect to the board:

well... I guess I must have just broke the board when I was trimming it, because it doesn't work anymore. I did some more testing and I can't find what is causing it to not work, but there are a few more things I might try.

when I power it on this is all it displays:

post the pic of your trimmed motherboard here, both front and back

Check if anything changes when connecting av out here.

I connected the av there, and it unfortunately made no difference.

after this failed I noticed that when measuring the voltages from the voltage regulator, most of the voltages are almost half of what they are supposed to be (ie. 5v line read as 3.4). Is that normal? when I disconnect the wires from the voltage regulator, all the voltages are normal.

that’s not normal, Also what are you powering the reg board with?

you have 1 more 3.5v line you didn’t solder on your board.

I'm just powering the board with a 3A usb charger.

what do you think it causing the voltages to be so wrong? I do have pretty long wires, but I was measuring the voltage directly on the voltage regulator, so I don't think that's the problem. Also one thing I have not mentioned is that the voltage rag makes a high pinched buzzing noise, but only when its wired to the ps2 board, which I don't know if that's normal either

Disconnect the wires from the reg board and test all the voltages make sure they’re all good.

give the motherboard a good sanding I see some rough edges.
