CRT madness!

I've been working on a Solar/Wind backup power source for my garage and in case of zombie apocalypse. It's a bit of a lockdown project to keep me sane(ish).
Anyway, there's 10 large(20KG+ each)120AH marine/leisure batteries hooked up to store the power and various funky electronic shenanigans going on to run and monitor all this.

What's this got to do with CRT's?
Well, I've been power testing various things to see how long they might run on the stored power(while never dropping below 50% of the stored power to keep the batteries healthy). After testing 3D printers, heaters, house security system and and loads of other things I got to wondering. How long could I run a retro system off just one of these batteries and what about one of my PVM's?

The answer is, be careful!! I've a few devices to convert the 12v battery source to 230v and got them mixed up and plugged in a PVM to a modified sine wave inverter instead of the much more expensive pure sine wave inverter. PVM is fine, but wow was there some weird noises coming from it and flickering on the screen(a little wee came out of me i think

)!
I switched over to running the megadrive through the OSSC and playing on a BENQ 23" monitor(everything running off the pure sine wave inverter).

For those interested in the results:

Console: Sega Mega Drive (region modded)
Game: Thunder Force IV
Extras also running from same battery: OSSC, BENQ 23" LCD Display
Source: x1 12v 120AH battery running

Runtime: 12 hours (50% remaining battery)

Be careful what you plug your stuff into

At least now you know that you'll get half a day more then the rest of us when the apocalypse happens

They really really missed a trick not bringing the Virtual Boy catalogue to the 3DS, it would have been fantastic, maybe include a colour-ized version with the originals.

It's a VB with a hacked AV out connected up to a Philips Discover space helmet TV from the 80s.

They just so happen to work perfectly together visually!

No VB on the 3DS was absolutely mind boggling, I wonder was there more to it like some licensing issue? (although it's all first party really isnt it?)

A quintessential Nintendo approach, that one. Even if the 3DS hadn't got the horses for proper VB emulation...they could have source ported all the games & sold them as a Virtual Boy Pack. Granted, a bit of work for something only hobbyists would probably buy....but Nintendo has the budget of a small country....how they make decisions sometimes truly baffles me. They're nearly always one simple step from perfection, & decide not to take it.

Someone over on the CRT Gaming subreddit managed to pick up a Sony Trinitron KV-36FV310 for ten dollars.

I've seen pictures of them before, but the scale with a person beside it is new to me, the bloody size of the thing!

Wonder how you'd get that up a stairs?

I see it accepts 1080i

Just to make it even bigger, 36 inches in US CRT size is 38 inches in EU size.

I wonder did any ever make it onto our shores?

The grundig I have is the biggest CRT I can remember seeing. The yanks so everything bigger in fairness

o1s1n · 09-06-2021 3:49pm

My mam just liberated one of my childhood CRTs from my grandparents house. A little 14 inch PYE portable. Absolute workhorse so it was.

Played everything on this from my Aunt's Atari 2600 and Sega Megadrive up to Gran Turismo on the PS1. In fact the first time I ever played Gran Turismo was on this CRT as my grandparents gave it to me for my birthday one year, along with the Dual Shock pad.

Switched on perfectly, first time.

Fancy OSD version

Genuinely more excited to get my hands on this than a lot of my pro monitors. To top it all of, it's RF only :pac:

I've an ancient 12" b&w tv from the 70s and it's perfect for the Atari Pong console I imported from the States.
In fact, it's the only tv it works properly on

Colonel Panic · 17-06-2021 11:18am

Got a SCART to BNC adapter earlier in the week so took some time to tinker with the monitor I got off o1s1n.

I'm running on very little sleep, so the issue below took me longer to figure out than I would've liked. The blues over RGB were all wrong, so I started to calibrate gain to sort it but it just wouldn't work. Note the extra blue on the side of white bars.

This is the same thing over composite

So, turns out, the out ports for RGB are a little... fragile. I replugged the terminator in blue and sorted it! (The CRT is running a real SNES, the monitor a MiSTer)

Then I had to dial back the gain on green and blue... It's better in person, but I think I'll leave it at this point for now...

o1s1n · 17-06-2021 1:50pm

Nothing quite like when a bit of CRT calibration comes together, glad you got sorted!

Really looks lovely and I'm regretting selling it already

Jack burton · 09-08-2021 4:01pm

So my good Sony CRT has a PSU issue. Keeps turning on and off. Now usually I'd just replace it with something else but it's a KV29 so going to look about getting it sorted out.

Anyone able to point me in the right direction for parts etc? Or just a case of get it open and see what comes out

Jack burton · 20-10-2021 7:00pm

So I picked up that beast of a PVM the weekend.

Now it's time to get my permanent CRT setup going. Been chopping and changing things for a while now but time to get things sorted.

So I need a scart switcher and a bunch of console RGB cables.

The switcher probably the most important for the PVM. I don't have tons of money to spend to the Amazing switchers that are €100+ are out for me.

I was thinking about risking it all on one of the AliExpress ones? No idea of the quality, probably ****? Might be good? Does anyone have any idea?

Colonel Panic · 20-10-2021 7:14pm

RetroGamingCables are coming out with a passive, chainable switcher soon. I prefer passive, manual switches personally.

There's also this: https://otaku-games.com/6-port-rgb-scart-switch.html

They also come with an acrylic case which looks useless and I've seen some decent 3D printable ones on Thingiverse.

As for what you've linked, I'm sure it would be okay. PVMs eat up all sorts of voltages. Be careful with scalers if you also output to one of those.

And... if you ever don't want that PVM, I'll take it :D

Inviere · 20-10-2021 7:28pm

@Jack burton from memory, try find a manually switched rgb unit. The auto ones can 'leak' voltage between connected units.

Steve X2 · 20-10-2021 8:46pm

The revised Hydra 2 switch is very good. Pricey, but not as pricey as the gscartsw. If you happen to be VAT registered there's some savings to be had on the site.

https://lotharek.pl/productdetail.php?id=290

If going with the Otaku switch, make sure you are aware of the voltages etc. https://www.retrorgb.com/otaku-6in3out-amplified-auto-scart-switch-review.html

Jack burton · 20-10-2021 9:59pm

The hydra mini revisited looks like it would do me.

Tbh this is a rabbit hole I didn't plan on going down. I'm in the CRT Facebook group and seeing guys just spend a ton of money to get these pixel perfect setups and not actually play games on them has just soured me on it

Like for a really good picture on the pvm I need a scart switcher and some good solid RGB cables really? I know next to nothing about framemasters, scalers etc.

Colonel Panic · 20-10-2021 10:09pm

If you JUST want to output to your PVM, then forget about scalers. I just mentioned it because the switch you listed will output to multiple sources and some people use it for PVM or to an LCD (via a scaler) or video capture device.

Jack burton · 20-10-2021 11:05pm

Yeah just output to the PVM. I have a good lot of crts so I was thinking a 2 out spread across them would looks pretty nice. But just output to the PVM is the main thing. 3 consoles hooked up I think would be a nice little setup on it. Mega Drive, PS1/2 and a SNES

I do want to get the big pvm with the 4 smaller ones all setup for the sake of it. But I just use a composite for the smaller ones. More of a novelty thing really haha. Just run the output into one and chain them together

Jack burton · 23-10-2021 7:33pm

Having some snyc problems with the new PVM. Trying a RGB GameCube herr

Tried messing around with it and no joy. Works great on my 9 in Sony pvm.

Asked a guy I know and he said some PVMs are a bit picky with syncs. So it mightant like this PAL CG.

I'll test it out again later wity mega drive and PS1

Jack burton · 25-10-2021 9:27pm

So update on the big PVM, this is not a nice read

Tried it with the mega drive and got the picture syncd and was looking good. The blue was a big heavy and needed some geometry sorted so went about doing that.

Figured that I needed and internal pot adjustment so was seeing where to go (didn't even open the case as this point) and pop. Something went and I was left with this image

Green channel gone....ok probably a cap or something. Opened up the side panel and saw this bugger

Ok probably this **** cap causing the problem. I can fix that. No massive deal.

Said I'd check a few other bits and pieces tonight though and see if I could see any other blown caps. Had a look, saw nothing sinister. Turned it on.... sizzle, crack, pop and magic smoke released. Bad times. Still wondering where I can do from here with it. Here's the current state when I switch it on

That component is an inductor, looks like it’s failed short circuit and could have caused damage to more components upstream :(

nightmare to work on without schematics

Steve X2 · 25-10-2021 11:43pm

Might be of use if you have a go at the repair.

Jack burton · 26-10-2021 11:13am

Even with schematics it's way over my skill level to repair.

Having a right **** run of luck this year. Have 3 chassis going off for repair. My MK2 board has a problem with the blue colour coming from the board. My 29 inch Sony crt psu is fucked.

I'll have to end up with grail pickup for €5 or something to balance this out 😂

Jack burton · 26-10-2021 6:37pm

Well there's a TV tech lives locally. He's a friend's dad so he's going to take a look for me.

"Im up to my eyes at the moment but I'll have a look at it but can't promise anything it's been so long since I've repaired these and of course parts are scarce"

If I can even find out what's wrong it will be a start

dav09 · 27-10-2021 2:12am

We have great fun trying to keep CRTs running, seems like one goes poof every few weeks. Donberg seems to be where a lot of people seem to get the parts or from tecknoservice in Spain or a few places in USA, not sure the exact tech in PVMs if they differ much from Arcade CRTs but in theory they shouldn't.

Jack burton · 27-10-2021 10:36am

Nah it's pretty much the same basics but just a lot more packed into the pvms. I know a lot of the arcade chassis repair lads won't even bother with pvms since there's so much to them

Actually talking about tecknoservice. My brand new chassis from them for my MK2 had a cracked flyback. Maybe 8-10 hours of use is all. Had to to back and forth with him a bit to get a deal for the new part. Hopefully it will be here soon though

o1s1n · 27-10-2021 11:02am

Cant believe that's happened with that monitor, really sorry to hear it :( Yeah grantspain and the likes wont touch PVMs due to all of the boards, not worth their hassle.

Fingers crossed with the TV dude, be such a shame to see something with low hours like that not fixed up.

Inviere · 27-10-2021 1:17pm

Something similar happened to me. Steve bought the stand up Ridge Racer cab off me, and very shortly after taking delivery of it, something went pop on the chassis. Bloody things :(

Steve X2 · 27-10-2021 4:30pm

https://www.boards.ie/discussion/comment/118079844#Comment_118079844

Yeah, sent it over to grantspain in the uk and he fixed it up.

I actually have a job for him at the moment, not sure if he's still in the game though.

CRT madness!
