Special Thanks to chrysolophus.amherstiae and Derf for sourcing a physical copy of this incredibly rare service manual so we could scan it!
Here's the last drop of PVM 2030 scans - Supplement 2, 3, and 4! These contain updated schematics for the D, B1, and B2 boards. Refer to the cited serial number ranges or part number variations to figure out if they apply to your model.

Sony PVM 2030 Service Manual Supplement 1 : CRT Database : Free Download, Borrow, and Streaming : Internet Archive
Sony PVM 2030 Service Manual Supplement 1 for serial numbers above 2,000,000
Following up my last post about the Sony PVM 2030 service manual scan, here's ANOTHER ONE. This time, Supplement 1 for serial #2,000,000+ models. These are the ones where Sony switched from the VTR port to an S-Video port on the back. archive.org/details/sony...

Additionally their package included 3 supplements to the service manual, which I will also scan eventually. This is a huge win for CRT preservation and I will continue to scan all of these rare manuals.
*** If you have a rare service manual, please lend it to me for scanning ❤️ Feel fee to DM. ***

This was a collaborative effort between myself, Derf (@consolemods.org) , and chrysolophus.amherstiae (who owned a physical copy of this incredibly rare manual, originally sourced from Canada!). Derf put me in touch with chrysolophys.amherstiae who then shipped it across the US to me for scanning!

The seller was forced to stop because of the stupid tariffs. Hopefully one day it will return.

The Sharp SF1 is fixed!

Update: its fixed! Turns out there is a 5v reg on the TV board for the SNES to use, but that wasnt even the problem. There is a PNP transistor that pulls the 5v low for the reset button and that transistor was dead. So 5v was being pulled low 100% of the time. I'll document more about it on my site

Yeah I just confirmed that on my end. Nothing is labeled but pin 1 of the EC connector is tied to VCC all over the SNES. The TV board is the 5v supply so time to hunt there.

Thank you! TV was previously working and brought in for a recap. TV board has been recapped already, plus the SNES board and the transformer board. Only thing I haven't recapped is the encoder board you mentioned.

Yeah that's already known, it's affecting the multi out but nothing else so far. SNES was working before the PSU problem killed it

I've gone and labeled all the chips I can read right now. Nothing resembling a regulator so that leaves me to assume the 12v to 5v regulation is done discreetly somewhere in this 2nd pic

Yes, those two transistors are the only source of warmth on the board after 3 min of being powered

Hmm would an everdrive work for that or do I need to buy a special cart?

CPU has already been swapped in the last so unless it killed the new one it's probably (hopefully) fine.

It could, but 95F is not exactly "dumping current to ground" hot like I would expect. Ideally I'd like to find where the 5v source is before pulling random transistors.

The 7812 regulator on the TV board feeds some of the input wires for the SNES and it's switched when the SNES power is turned on. So the 5v reg must be on the SNES board... Must be SMD? Guess I should follow the 12v(on) pin I found and see if it leads to anything related to 5v

Switching the SNES power switch on/off changes where the 12v supply is - which seems to be a logic controlled operation not a simple "switch changed the pins that 12v feed" situation. Power switch doesn't ever have 12v. So maybe something is alive, I don't know. Help! Lol

The SNES is from a Sharp SF1 where the 12v power supply for the SNES blew up. I've repaired the PSU and restored 12v power to the SNES but it does not seem to be running. Only thermal activity I see is a couple warm transistors. The Nintendo chips are not warm at all.

The SNES I am working on is not your average recognizable variation of the SNES hardware, does not follow the published schematics, and runs off 12v instead of 10v. I am hoping someone could look at the board and recognize what each area does what.

I'm putting out an SOS for anyone in the community that knows SNES hardware like the back of their hand. I don't mean like installing mods or replacing capacitors, I need someone who could diagnose a bad CPU, bad smd transistor, etc. this is for a rare Sharp SF1 tv 🧵
