Fudoh's ode to old display technology

[Fudoh]

Don't know if you even need a sync stripper, maybe not. But you can of course just use a Sync Strike as means to adapt a scart input to a HD15/BNC output. And you can't use any scaler on a 15khz display.

Thanks for the heads up. Just trying to use the bits of hardware I have to hand rather than having to buy more bits. If they don't work, then the BNC > SCART lead mentioned is fine.

You have to find some info on whether you need a sync stripper or not. If not, then it's just about making the connection. Whatever way you can connect your RGB sources to the display, it will be fine.

Yup, quick search shows others using the Sync Stripper to VGA > 5BNC cables, with success. Will report back when I'm up and running.

Well, maybe I was not clear in my question - what I want is a professional monitor BVM (14g5u model) with an expansion card BKM-20D, which is on sale for a good price here.

I would like to start using the emulator on a computer, RGB input and out from BVM monitor and modify the signal to component video monitor bvm, take my TV Sony Wega 29 "SDTV with component video input in, with scanline in 240p 288p up to this in my arcade cabinet.

Getting a transcoder with component video output 240p here in Brazil is very difficult and expensive. I thank those who read and can answer this question, sorry my english because used electronic translator

unfortunately it tells. Can't really make any sense of it, sorry.

Same here.

There are three things mentioned: A computer, and three displays.

There are three possible questions here: Computer to BVM, computer to Wega 29" with YPbPr, or computer to arcade cabinet. All are going to have different answers.

Unless the question is for having three displays in use at the same time, which surely cannot be advisable, I think the question needs to be rephrased.

I believe what he wants to do is output from his PC to the BVM, have the BVM convert that to component and then take that to his arcade cabinet w/WEGA display via component . At least this is what I think he is saying. Is this what you are hoping to do? BVMs input/outputs are pass thru only as far as I know and can not take one type of input and output another. It seems from his post that he wants to convert the PC signal to component by using the BVM card and that I do not believe is possible. If this is not what you are after than sorry.

[Ed Oscuro]

Ah, I think you're right. Well, that is certainly a very convoluted way of doing things, I realize the poster says it's too expensive to get the proper equipment, but...

There may be something that can be done, although you'd not explicitly need the BVM to do it, would be to get a relatively cheap RGB to component transcoder. That could be used on input direct from the source console, or probably from the passed-through video in the BVM.

[Thelson]

It's just that the computer uses VGA / RGBHV I want to use 240p on my sony wega TV with component input, wanted to use the plates of the transcoder bvm component video out to tv sony wega. the transcoder would have to pay import taxes and even absurd here. Very grateful.

Maybe somebody else can find something at an even better price, but that is about as good as it gets for price.

Two questions I suppose are appropriate for this thread,

1. Is a PVM20L5 worth $180-200 shipped?

2. Where does one find a PSU for an Emotia unit? Everytime I look into getting a 15khz-able CRT I look into getting a downscaler, and all the ones I see are sold without the PSU. Which seems to be a unicorn.

[Thelson]

I am thrilled with your quick response I'll search here to see if I can extract 15khz 240p signal to component video. I really appreciate your opinion.

crap, just when i blew my money on a couple of SLGs a bvm d model shows up for auction in my vicinity.
just my luck

A recycling center in Austin was selling a bunch of monitors and my friend was able to grab a couple of Ikegami TM20-18Rs. They were in the best shape out of everything on the pallet.

Not sure what we have gotten ourselves into. The manufacture date is 1997 and they power on. I will know more when he gets them over here, which will probably be the end of next week. Hopefully we can figure out a way to access a test mode.

Well shitty shit. We finally got a chance to run the test and both of them are junk. One of them suffers from a collapsed raster and the other one glows a bit, but nothing displays on screen.

Looking at another option for a 13" PVM in the area now.

didn't you wait for weeks for this? really sucks it didn't turn out in your favor.

anyone know if the bvm D series supports optional rgbhv inputboards? i think i've read here that vga inputs were abandoned with the A series, but can't find anything that suggests rgbhv support for the D series in the pamhplet fudoh posted.

[ExitPlanetDust]

Yeah and it was difficult just to get everything set up so someone could go pick them up. I was kind of numb about it all (still am). I was talking to him over the phone while he was running the tests. I still haven't had a chance to make it over to his place. That's probably a good thing. I would have roll them down the freeway.

[Fudoh]

I think we established that you can feed RGBHV to the RGBs input using a T-connector as long as the chassis supports 31khz.

ah yes, i remember something like that. didn't remember the details though, but it seems it should be fine with this bvm model. thanks guess i'll have to hope the price won't shoot too high. this 24" model would fit very well into my setup.

the bvm models have absolutely no audio hardware (amp/speakers) at all, right?

[Dennis]

Hey guys,
I'm about to buy this CRT:


The seller says it's an Sony PVM-20M4E, but every pic I can find on google images shows a different model
Are there different models with the same model number or something? Should I buy it?

[Fudoh]

I would have said that it's a 2130 or similar. Definitely an older line than the 20M4 series.

Please someone, who is into CRT technology, write about the Bang & Olufsen B&O MX4000 or the B&O MX7000 . I would love to get one of these for saturn games.

[lostinblue]

I'm sad today. My PVM4M arrived like this:








it works and it's beautiful, but they broke the circular parts where the front screws go and it won't close, I'll have to open it and I don't even know how to. (the screw that is missing was me, then I realized there are back screws I can't get to.

It's sad because it would be pristine otherwise. The front bezel should be sold somewhere and I am most afraid of nuking it.

How do I unscrew these?

[22point8]

You only have to undo the screws, the nylon rivets can stay where they are. If you look back through the pages there should be an m4 service manual. My PVM 1454QM has one handle missing and the bottom is cracked and the only problems it has is it can take 15 minutes to vertically centre the picture (only about 1cm out at start up) and a rotated screen that all my CRT have, must be geomagnetic.

I think I found them, but they're on sendspace and the links give out a "sorry, the file you requested is not available." message.

I unscrewed all the screws on the sides and still nothing the nylon rivets are making the iron enclosure part stay just where it is. I'll keep fiddling with care.

I see.

Thanks, that actually makes me feel better; not for the fact that you have some problems in your unit, of course, but that units this old are hardly pristine. I'm just sad that this one actually was, before transport.

I should be happy it still works.
