Worklog N64 Portable (No name yet)

Swapped ram chips with 4mb and relocated PIF, worked great. Trimmed board and now wired it up, cannot get it to output a video signal. Chips get warm, does anyone see something wrong?

 

[Nicholas298]

I need help please. I have been troubleshooting my trim for 2 weeks. Here is what I've tested so far, please give any advice or things to test

Board worked fine with pif relocation and 4mb RAMBUS chips Before trimming
Jumper pack and cartridge are in and have been removed and reinserted several times
Sanded up to 1500 grit
Tried different jumper packs and games
No shorts between voltages and ground
3.3v on all 3 locations
5v on the one location
RCP, CPU, and both RAMBUS chips get hot
All Pif connections are correct (tested several times) 23 goes to “24” on the pif relocation, right?
4.7kOhms 3.3v to GND
5.9kOhms 5v to GND

R6 on your PIF breakout board appears to be labeled "01Y", which means 1Ω. It should be 1kΩ based on the trimming guide. Maybe you should verify all the resistor values on the PIF board?

I fixed the resistors but still no boot..

This might be a dumb question as you seem knowledgeable, but have you verified that the screen is being powered and that it’s on the right input?

I appreciate the suggestion, I’ll try another screen and see if that works

 

[Nicholas298]

Got my original trim working! It was the screen! It was on the wrong input lol

Assembled a 64AMP by Gman and got some heat sinks, gonna use original thermal pads

Man I haven't seen an N64 trim in a while, love how clean the wiring is running through vias.

Audio AMP on and working, celebrated with the DK rap Next step is Fusion modeling and controller pcb design

 

[Nicholas298]

Rcp wiring, too EZ

 

[Nicholas298]

Putting in that work into fusion, Hope to have 75% finished by end of this weekend. LMK what yall think of this design and feel free to add ideas or suggested changes. This is heavily inspired by the Ashida By Wesk

You do not want to see how messy my fusion Timeline is lol. I am working everyday on this case design, here's a few pics. Will use all OEM buttons, L button will act as Z, No Dpad as of yet, thought about using a PSP slider as a small D pad. OEM screws as well

Also test printed a side of the handle and I got it feeling pretty identical to the OEM controller

I plan on making button combos to adjust screen settings
