NAOMI No Boot, done plenty of diagnostics

[tomoro__]

Hi, having an odd issue with a NAOMI. I get no boot, black screen, no sound, but have gone through all the usual steps.

Voltage is spot on and is coming from a sun psu
Swapped it into the same power setup as a working NAOMI, no dice
Swapped in the confirmed working bios from that
Supercap has been replaced
Fans both run just fine
ICs are also getting proper voltage on the main board

If anybody has any leads for me I mightve missed at this point please let me know!

Have you tried a cart game? I've got a naomi that pry needs a recap as it refuses the netdimm until its warm. Black screen of doom otherwise.

I haven't yet actually, I figured since I haven't gotten to even the NAOMI splash screen with nothing attached a cart wouldnt change that, but i might have to give it a regular game a shot just in case

Sounds to me like the Naomi is faulty.
