So I've been working on a 4 layer board and I cannot get it to boot. After troubleshooting, I can't seem to find a problem. Turning the console on results in a black screen, occasionally flickering to the blue no signal screen for a split second. My trim looks fine and I've only wired up the essentials (USB, screen, regs). Here's what I've troubleshooted so far.
Software
Software
- Installed Nowifi PM first and foremost. Tested to make sure it worked.
- Tested outputs before applying to system. Receiving a nice, stable output for each.
- Wired up to board and ensured there were no shorts on any of the lines.
- Tested the voltages on the board when the console is turned on, they look fine.
- Yes there are all in the right spots.
- Made sure the trace was cut by scraping further down the line and making sure there was no continuity.
- I DID NOT test to make sure this worked before trimming, didn't know that was an option.
- U10 was NOT outputting 3.3v on the top right pin, proceeded to desolder the U10 and manually touch a 32g magnet wire from the 3.3v line to the data line to the GPU to see if that would cause a boot after turning on, did nothing.
- Resoldered the data line to GPU to make sure it was properly attached.
- Checked continuity from via to pin on the USB module.
- Tried both USB ports to make sure I was using the right one.
- Waited 30s after booting to see if anything would come up.
- Wired reset to GND to see if it would boot to priiloader.
