Back by popular demand.......Panasonic 7" LCD monitors

Just an update, Nephasth is making cables for these if anyone is interested. You can see his thread here: http://forums.arcade-museum.com/showthread.php?t=200118

(Thanks man!)

I received my 2 monitors today and they look great. Wow those connectors are small but turns out I had some 3 pin micro plugs which are made for R/C micro servos and are the same size so I used one 3 pin for power and 2 of the 3 pin plugs for the signal. I just had to trim the edges of the 2 plugs so I could plug them in next to each other and it worked like a charm. I wired one up to my GME MT830A monitor test generator and I got a picture but it wont sync correctly. with only one of the sync wires the picture looks great but slowly rolls and wont lock. With the other sync wire the picture locks in but the color bars run diagonal across the screen and are split. If I connect both sync wires they look the same ,color bars run diagonal across the screen and are split but the picture rolls. Both monitors produce the same condition so I am sure it doesn't like the output of my signal generator. It only puts out separate horizontal and vertical POSITIVE sync.which I would have thought would work. I'll have to wire up a JAMMA board and test again.

Just a heads up....I am starting to run low on these monitors. I have a few people with pending payments I'm waiting on, so those are reserved. The big box is looking pretty empty though......

Ok guys, I have a few that are pending payment, so I'll have to check for sure when I get home, but I think I'm down to the last 10 available. (I am keeping a few back to cover for problems popping up.)

If you want them, get them now. When they are gone, they are gone for good.


Thanks!

I finally got the monitor to work but it would only work with a JAMMA board but that's what it was advertised to do so that's good. I still don't know why it doesn't work with my GME MT830A monitor tester. I also tried it connected to a Electrohome NTSC decoder that's used for Dragon's Lair as I was hoping to use the monitor to view video from a composite video source but wile I got a video picture that was locked in the screen was split with the bottom on the top and the middle of the video on the bottom and the left edge of the video screen was cut off just like the test patten but the test pattern had a slow roll not quite locked in. It should make a great portable JAMMA test monitor. I wired up a JAMMA harness and connected my Ray Storm. I had to turn the contrast and brightness all the way down and the picture still looks a little washed out but it doesn't look to bad. I suppose it's because of the monitors resolution. I'll have to dig up some more JAMMA boards and see how they look.

 

[Raven]

I've got about 8 left available.

 

[Raven]

Ummm....yeah, let's make that 3 left.

 

[Raven]

and.....we're......DONE! (assuming these last few folks pay me)

I did some more adjusting on the monitor,this time with my Street Fighter 2 CE and it looks much better than Ray Storm did. I also tried out all the control pots on the back of the monitor, even a couple I don't know what they are but they did make the picture better after I adjusted them. For the most part it was easy but hard at the same time as adjusting one pot affected another so their was a lot of going back and forth tweaking each pot. One word of advice, don't use a metal screwdriver to adjust the pots because it shorts out the pot and you cant see the true adjustment. I used a ceramic tip aliment tool with a 1.3 mm flat blade. Plastic should work if it's small enough to fit the pot. The pots turn a full 360 degrees with no stop but they are only a 1 turn pot. I did play around with all the pots, even the 2 unmarked ones and I explain that in the video. They all were helpful in adjusting the picture but it dose take some time and patience but it's nothing like as hard as converging a picture tube.

The last ones went out this morning.

I got mine the other day thanks. Just waiting on these awesome cables to be made.

Isn't that tester only 31khz and VGA? The LCD is 15khz.

 

[EclipseEye]

Dude, both my screens arrived in the UK yesterday intact! Many thanks.

The GME MT830A monitor tester has MDA,CGA,EGA and VGA
In CGA test mode it worked fine on my WG 4600 that I rebuilt for my Frogger and Pac-Man so I don't know why it doesn't work with this LCD monitor. The Electrohome NTSC card from a Dragons Lair,I have been using with a 13" G07 monitor but it doesn't work with the LCD monitor either but the LCD monitor has worked on every JAMMA game I have tried so far. Their has to be a difference in the sync, I was hoping someone might know.

 

[demogo]

Is that the deal with these standard res monitors? They're the same freq/resolution as the old CGA computer monitors?

They have to be the same as something else because otherwise we wouldn't be finding them like this. No one's going to be producing these for video games...

 

[Raven]

SaminVA's stuff is really helpful, but I think it would be better broken off and put in the monitor section or general. It's less likely to get lost, and more likely to get seen there. The info might be of use to some of the other members who aren't checking back on this thread now.

 

[jkoolpe]

Shucks...wish I had seen this earlier.

If anyone decides to sell one of theirs in the future, please let me know as I could have used one and would have picked it up if I had known about it in time.

Oh well....
