Update on the Sony PVM-2530: probably should use RGB before diagnosing color issues (e.g. luma). I did have to get in my custom CMPTR board to do it, but everything lined up perfectly. I do need to fix the geometry a bit, but for right now I think I'll be playing a few games after work.

Got a present delivered in my driveway, and it's definitely TV shaped. A good indication of weight is the fact it's strapped down on a palette.

A Sony PVM-2530 packaged up snugly in cardboard, plastic wrap, styrofoam.  It's on a very nice palette as well sitting on the edge of my driveway.

The Sony PVM-2530 is now in it's new home: a proper AV cart. Still need to calibrate everything, but it's one step closer to being used and enjoyed.

First power on of the Sony PVM-2530: major convergence issues. Fortunately I have the service manual and this should be very correctable. Still need to get the speakers cleaned up and attached to the PVM.

A grid of "white" squares...but the convergence is bad.  You can see the individual R, G, and B colors not lining up in the horizontal plane and are also a bit off in the vertical plane.

So, figured I'd "fix" the mono output from the JVC TM-H150C CRT monitor by grabbing the Sony speakers off the PVM-2530 and attaching them to an amp. Works perfectly as the speakers are shielded and barely fit onto the second shelf. I officially have stereo sound for the smaller TV.

A set of Sony APM-X5A speakers connected to a cheap Pyle stereo amp.  The SCART breakout cable's RCA audio outputs go into the amp, and the RGB connectors go into the back of the JVC CRT.  The screen is showing Final Fantasy 6 being played on the MiSTer beside it.

Why do I keep buying CRT TVs? I now own 3 of them, and the new one is a Sony PVM-2530. I haven't seen many around, and I figured that September is a good time to grab a waaaay-too-expensive TV.

A quick schematic for a CMPTR breakout PCB. This really only handles RGB, but should get the job done for the CMPTR connector on the PVM-2530.

Got the convergence mostly fixed after trying to fix it previously. Learned a heluva lot, but time to enjoy the fruits of my labor.
