I'm glad you found a solution.
The orange board is a prototype for setting a ROMSIMM in the PDS slot of SE/30.
If the fixing hook of the original ROM socket on the logic board is broken or the pin contacts are not making good contact, I can now set the ROMSIMM without using the original socket...
I don't know if a 45 degree socket existed, but I have a 64 pin socket with a 25 degree angle.
The insertion angle is 60 degrees and locks at 25 degrees.
I got it to repair my SE/30, but by mistake I got one that wasn't straight.
That was over eight years ago.
The model number is AMP 822138-1...
That's a good suggestion.
However, 350793-1 and 350779-1 are 6.35mm (0.250") pitch products, but the direction of the pin hole is different from the actual product, so I checked it.
I think the following product with 6.70mm (0.264") pitch is correct.

Your information about FUSE is excellent.
I have had the same problem for the past 4 years, but it turned out that my FUSE was also broken.
Based on your information, it seems almost certain that buying a new FUSE will solve the problem.
Thank you.
VIA of SE/30 is
338S6523 (11484 -28, -30, -44 etc. ) = R65NC22J (Rockwell) VL65C22V-02QC (VLSI)
Model numbers are from multiple SE/30's on real machines.
I think the closest thing to R65NC22J is W65C22N6TPLG-14, not W65C22S6TPLG-14.
Please refer to P.32-35 and P.50 of the PDF.

The RIFA capacitors that are the X2, Y2 capacitors on Analog Powerboard can be substituted with the following capacitors:
US C38 (0.1uF) PHE820ED6100MR06L2 (399-7608-ND)
US C33/C37 (2200pF) PHE850EA4220MA01R17 (399-5416-ND)
International C37 (0.47uF)...
Remove with this special tool or a similar tool.

But it's cheaper to process it with a new housing.

If the screen is black even though the power supply unit is on and the cooling fan is spinning, there is a possibility that +4.7V or more power is not being supplied to the 5V terminal.
If you have a SONY CR-44 or AcBel power supply unit, you can adjust the voltage with the internal trimmer...
