View Full Version : Sony PVM-1390
lnx64 07-30-2013, 08:53 AM I have a Sony PVM on my bench and I wanted to hookup my Sega Genesis to it via RGB, and damn what a chore that was! I had to basically hunt down resistors and capacitors.. Apparently I can't just connect the RGB lines and composite sync lines.
The RGB lines all needed a 75 ohm resistor added, or the picture was too bright and caused a shrink in the vertical size of the picture. Also, CSync needed a 220uF cap and then a 75 ohm resistor.
:S Why so complicated?

Some interesting functions on that connector...

jmetal88 07-30-2013, 10:13 AM It's not Sony that's the problem, it's Sega, haha.
Check this page out for more detail in getting RGB from various consoles:

With my Atari Jaguar, I can just connect the lines directly and get an awesome picture on my PVM.
lnx64 07-30-2013, 10:48 PM Oh, this picture!! So clear and sharp!

Rod Beauvex 07-31-2013, 07:31 PM Not a game, an internet meme.

I'm surprised it didn't have a problem matching the 15khz scanning rate.

Thanks. Multisync monitor maybe?
lnx64 07-31-2013, 07:50 PM This PVM is only for 15KHz..
lnx64 07-31-2013, 10:12 PM by any chance, anyone know how to fix pincussion problems on this monitor? there's ZERO external adjustments for it.
Jon A. 08-01-2013, 01:15 AM I have the Nyan Cat site open in another tab. That's one addictive, rainbow-trailing Pop-Tart. So far I've Nyaned for... 220.7 seconds, and that doesn't count the time I was on there before.
Just so I'm not totally off-topic, I tried a couple of Google search strings for your problem with no luck. That's quite an obscure piece of equipment. Good one though.
lnx64 08-01-2013, 04:24 AM I was able to fix the pincussion. Inside there was a Pin-amp and pin-phase adjustment. Not perfect but quite better now.
I adjusted V-size so the bottom isn't cut off, but now there's a little gap at the top, but there's no V-position POT's inside.. I adjusted the focus, it's at the extreme edge for focus now, and is as sharp as it can possibly get anyway.
I experimented with a POT called H-Stat and that basically screwed up convergence, so I put it back since convergence was nearly perfect already.
Rod Beauvex 08-01-2013, 11:06 AM 15Khz? What was this monitor meant for?
lnx64 08-01-2013, 11:29 AM medical i believe.. It has a very weird base and set of inputs..
mine was a movie prop in X-files (still had the same damn pincussion problem way back then too when seen on the show.. till i fixed it somewhat today)..
rpm1200 08-01-2013, 12:12 PM Good work! That's a nice monitor.
I believe the RGB signals going into the D-sub on your monitor would also work on the RGB input of a KX-1901/KX-2501/KV-20XBR/KV-25XBR, but you would have to use a floppy drive connector plug instead of the D-sub.
lnx64 08-01-2013, 08:21 PM Thanks, here's a video recording of what I have done to it, and it working now.

The sound is recorded directly from the real Genesis that's running this, which has been hacked quite a bit with a newer sound chip (clear FM synthesis than the original, but unless games take use of the digitized sound sampling function correctly, like gun shots and drum percussions, they don't sound better).
EDIT: Just realized, for some reason I knocked the focus off half way through. :/ whoops! I'm using a real movie camera for this, not a cheap home camera, so it has a large focus ring, I must have knocked it at one point.
zenith2134 08-02-2013, 03:58 PM Picked up two PVM-1390s today for free. They both work well, one needs grayscale adjusted.
Not sure what I'm going to use em for yet.. But they are nice to have.
Jon A. 08-02-2013, 04:34 PM Dang, nice score. Where did those come from?
zenith2134 08-02-2013, 04:41 PM Not sure about their history..got them from a fellow VK member.
Jon A. 08-02-2013, 05:04 PM And me in East J---s nowhere, as Brenda in Juno might say. Not exactly a lot of swapping opportunities. Well, none really, haha. Anyway, that's got to be THE monitor for Apple IIgs users, and anyone else whose vintage system outputs a 15.75 KHz horizontal sync signal.
Rod Beauvex 08-03-2013, 01:15 PM Genesis hacking, eh? Do you hang around Sonic Retro, any?
