I have an account on the other platform but haven't started regular posting there... haven't seen enough activity yet. But if you want to preemptively follow, here's the details:

@RgRDev @SHADOWSTRIKE1 did you ever post this? its been another 5 months. is there a way to get a refund?

[Andy King 📺 @dorksince93]

@usa_retro The one on the left is a 2950Q. You can tell because of the model number being in the bottom right. Also both monitors are sold :(

Thanks once more to chrysolophus.amherstiae and @DerfJagged for sourcing a physical copy of this incredibly rare service manual so we could scan it!

[Andy King 📺 @dorksince93]

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.

@elbuensaul It was really just the only approximate thing available for years (until now).

The first ever PDF copy of the Sony PVM 2030 service manual has now been uploaded to https://t.co/Ut7nNhU39q.

Once again thanks to @DerfJagged and chrysolophus.amherstiae for collaborating on this effort, more supplements for the 2030 still coming! https://t.co/s0YgLdtTNU

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. https://t.co/rVJrnuWUks

Also, if you're still following me here, consider following me on bsky instead. I don't come on this website much anymore for obvious reasons. My account is https://t.co/fkoskFs5HO

You can find this manual directly on https://t.co/Ut7nNhU39q, or on the CRT Database entry here: https://t.co/s0YgLdtTNU

@rtwlz I had a feeling since the data stopped flowing in. This was too powerful 😂 my only regret is not getting to see my neighborhood officer's route

[Andy King 📺 @dorksince93]

CRTDatabase should be back up within ~30 min

@CHPSanFrancisco Can we get an update? It's been hours of no movement.

[Andy King 📺 @dorksince93]

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's a PNP transistor that pulls the 5v low for reset and that transistor was dead. So 5v was being pulled low 100% of the time. I'll document the fix on crtdb.

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 knows a SNES like the back of their hand and could diagnose a bad CPU, bad smd transistor, etc 🧵

[Andy King 📺 @dorksince93]

Forgot to share a full pic of the back

[Andy King 📺 @dorksince93]

@qwertymodo @Voultar Yes I've confirmed in the meantime that 5v comes from the TV board not the SNES. Trying to find where it originates.

[Andy King 📺 @dorksince93]

@qwertymodo @Voultar 5v is around 0.1-0.2v and resistance to ground is 500 ohms. So far I still haven't found the 5v source. I think it's a discreet group of components instead of a single IC. The big IC on the back middle of the board is for driving RESET/
