help with PVM. to much blue

Post by soviet conscript »

yesterday I finally acquired a 19 inch PVM 1054Q locally to replace my 14 inch model. brought it home, worked wonderfully. Today I was playing the PS2 on it via RGB and suddenly the color went off and became overly blue. I suspected a loose connection so I fiddled with my blue in wire and the problem corrected. a little later it happened again but this time no matter how many times I fiddle with the BNC jack or try and reconnect it its overly blue. I tested the cable on my 14 inch and the color was fine so its definitely the monitor. any idea? the input for the blue cable looks just fine.

*update* after posting this I went back and tried again. the PVM was on for the last 10 minutes or so but not displaying. I powered the system on and the colors are perfect. could this of been a fluke or is this a sign of something possibly bad?

after more testing the composite jacks seem unaffected. only RGB and component give me the issues (both use mostly the same jacks). RGB will shift to strong blue hue randomly and when I was testing component it went overly yellowish after about 20 minutes. sometimes turning the monitor on/off temporarily corrects the issue.

does this seem more like a cap or solder point issue at the RGB jacks to anyone rather then something serious?

Check if you have 75 ohm / high-Z termination settings. If R and G are set to 75 ohms, but blue is set to high-Z, then Blue will be a lot brighter. I doubt this is the case if it just happened during use but it's worth checking.

Are you sure you don't mean PVM-1954Q? Did you buy this from a guy in Tempe? If so that is a PVM-1954Q and that monitor was complete shit. I actually had picked it up from him AND returned it to him. The monitor was worn to shit. There was a pretty strong white streaking, there was background interference that looked kinda like a flutter, two of the feet were missing (not a big deal), and it it had some mild convergence and geometry issues. Overall it looked like more of a pain in the ass to fix myself so I returned it for a refund. A few days later he relisted it on craigslist for $125. The guy knew it did not work, its why it was returned to him. I did not have the issue you are describing however I wouldnt be surprised if the problem had come up since then.

I am really curious to know if this is in fact the same monitor. I have never heard of a 1054Q and sony tended to name their monitors after the size of the monitor itself. I doubt they would have named a 20 inch monitor starting with a 10 so that kinda makes me think its the 1954Q. Either way if its from that guy in tempe that monitor was pretty worn out and tired.

Nah I did not but if its a 1954q and he got it in Tempe I can guarantee it will be the same one. PVM's come up VERY VERY rarely in this neck of the woods. Most PVM's/JVC monitors sold in 2015 on craigslist in this area were sold by myself. I did not fully stop buying, repairing, and selling monitors locally until I got the new Sony XBR and the Mini (which was in november 2015). We don't have a ton of video editing places here and the ones we do have abandoned CRT awhile ago. Even the local hospitals have dumped most their CRT's and even when they do dump more they are usually pretty badly worn. Most the monitors I have received I scooped up as great deals on eBay and shipped them in. Id fix them up, get bored of them, then sell them. It put more monitors in circulation locally. I actually find it kinda cool to see people posting their PVM pictures on the various forums not realizing they bought it from me.

But yeah, its real easy to find out if its that one, he just has to confirm what city he got it from. Also its missing two feet. Originally he had them on opposite corners but I removed them and placed them on one side so it wasn't wobbling anymore.

Yeah, I think its the same guy. did he have to test it from his car? it was listed for $125, I talked him down to $100.

Your also right, its a 1954Q. this monitor is pretty dinged up cosmetically but I found the picture to be pretty good. I didn't see any lines or anything, but I did notice a slight flutter you mentioned. it also has all its feet.

I think I actually bought a PVM off you about a year ago. a little pvm-14l5 (which btw is still going strong). I really have been looking for a slightly larger screen size though and with PVM's getting scarce I jumped at this one. seems beggers like myself can no longer be choosers.

nix that. its the same monitor. I just double checked and the two feet on the back are missing. I need to learn to be more picky but as you said pvms are hard to come by here and i was losing patience for a bigger screen.

If you bought it from a guy that wears all black and had a white durango in the driveway then it was me. If it was a 14L5 I can almost 100% guarantee it was me since the only other guy selling one in the past year is some yahoo down south wanting 400+ for one. If it has the flutter then that is the same monitor, it was also dinged up as well. There are no termination settings on it as I mentioned so that monitor is most likely having issues with its input card or an IC somewhere is going bad. In all honesty I would not bother fixing that monitor and if it has not been too long try to get a refund. The monitor needed to be recapped and did need a good deal of calibration done to it (convergence strips and all).

Now that I think of it blue was a bit high on it, just not as bad as what you mentioned. I just turned it down a ton to compensate. It sounds like the issue got worse. Contact the guy and try to get your money back.

I'm pretty positive it was you. I'll give it a shot. next time you end up selling a 19 or 20 incher keep me in mind, id appreciate it :)

As for larger CRT's in the major Phoenix area you might have a much easier time going the route I did. I bought a decent Sony HDTV and an XRGB mini. Although I use it for everything now I was using it and then a 14 inch BVM for my CRT fix. I ended up selling that one too and just use the mini now with an HDMI matrix switch that outputs to my PC monitor and the TV. But yeah, unless you get lucky on craigslist an upscaler is your easiest solution for a big display in these parts.

P.S. This is my new setup. Not as retro looking as a CRT but the convenience of it all out weighs anything a CRT gave me. It also still looks hella nice. It will probably be awhile if ever if I sell another CRT. I only had them because I was actively looking and experimenting with them. Now that Ive gone with an upscaler I havent been spending the money on them.

Nice setup, very organized! I feel bad for that MVS with the 161-in-1 3.3V "Fry my Neo" cartridge, though...

that is a nice setup. for me though an upscaler isn't really an option. I had an xrgb type device a few years back and it just wasn't for me so i ended up selling it. the nostalgia and aesthetics of a nice CRT for me are a large part of the retro gaming experience. Of course I wasn't gaming in RGB on my SNES when I was a kid but theres just something about gaming on a CRT as opposed to a big flat HDTV that I really require for it to "feel right". call me crazy i guess.

I have a buddy that recently moved to the area, he says hes worked on PVM's and arcade monitors before and he wants to take a look at the 1954Q. maybe if I can keep repairs costs way down this way it may be worth trying to repair. I don't have many options since as you said they are so scarce on the ground here.

until then I'll pull that 14 inch PVM out again I got off you

If the guy tried to burn you on a PVM in bad shape, that sucks, but if you are able to get it repaired then it will be a great monitor eventually. It sounds like a recap is one thing it could really use. It may have been a monitor that saw a lot of use.

Ive never had a problem with the 161 damaging an mvs system. I have been using a 161in1 for years now with no issues. I play the neo a lot too. Most people i know use them as well and have had no issues.

It is just the sort of thing that will draw more power than needed and can reduce the lifespan. A good solution for the future might be to create an interposer board that has level shifters to sit between. DB Electronics did a good write-up on the effects of mixing signal voltage levels incorrectly: http://gendev.spritesmind.net/forum/vie ... 170#p27335
