This weekend picked up a D9200 and a D9400 from a fellow KLOV'er so I can use them with a Sega Dreamcast and play stuff like House of the Dead 2, Confidential Mission, etc, in my Warzard cabinet (medium res, replacing with one of these). The tube from the D9200 looks like it may be losing red (screen has a yellow tint - though I forgot about changing the color tone settings in the factory menu), and the D9400 has neck glow but no picture/no raster (will investigate later). So, I attached the D9200 chassis to the tube from the D9400 (yokes are compatible) and the picture is mostly great (after adjusting size/position via remote board and adjusting H width pot on the chassis). The two minor issues I have now are a little curvature at the top of th3 screen and a half-inch or so black bar at the bottom. I have vertical position down as far as it will go, and adjusting vertical height in menu just causes the bottom of the picture to squish after the point I have it now, since there's "no room" for it to expand further down. Is there a way to many force the position down a little? And any suggestions for the little warping (see right where the dashed horizontal line meets the dashed vertical line) at the top? Other than that the geometry appears excellent and the picture is very good. I suppose I could maybe slightly and the yoke and then adjust pin cushion to compensate? Thanks for any tips.1000031226.jpg1000031227.jpg
 
Looks like there was a post with a similar issue many years back by @zenomorp - do you recall if/what you did to fix this? I know it was 15+ years ago...guessing caps? Granted I am probably using a different tube, and I don't think it does this only the one it came attached to, but I'm not positive.
 
The cap on the video input board on the 9200 gets roasted by the diodes that get super hot and are the main cause for the "No Signal" issue. As for the geometry, yes, the yokes are compatible but the 9400 uses a flat tube and the 9200 uses a curved tube, so when you mix ad match, you get slight issues like this. Of course, if you haven't capped it, that's step 1.
 
your slight monitor issues aside, that's awesome lol
It is, thanks! Bonus is Xbox 360 also supports VGA so I should be able to use it as a Guitar Hero arcade-ish cabinet too :)

Thanks. Yes I can't imagine it'll ever be perfect, but close enough. I was mainly wondering about the "squishing" at the bottom that you mentioned on your old thread, since I have the same thing (at least I think it's the same issu).
 
Thats cool. I have a d9400. Do the guns work?
They do, and it's awesome! I have some random Yobo gun I found locally and it works perfectly. Screen isn't swt overly bright, don't have the crank up the flyback to see raster lines. Also the gun supports rapid fire and auto reload so it's basically light a machine gun with unlimited ammo if you turn those on.
