Been a while since I posted; a lot of different things have happened since! In the original pic the "Left" Blast City is BS1 and the "Right" one is BS2.
Control Panel from Blast City One Cleaned and Back Together
Got a new BC and AC panel from
@alberto1225 and LOVE it! Put the thing together with brand new Sanwa parts and kept the original wiring. New coin slot and bolts too. I also kept the original wire ties, removing the old sticky residue and replaced it with double sided tape. Works like a charm and is back in it's original position. I threw the panel back into Blast City 2 because it's CRT is working and I wanted to test it out. I realized the Sega I/O is kinda weird and uses Button 4 and 5 on the JAMMA edge for the first two kick buttons, so cannibalized a wire from player 2 (the harness already had btn4 added from whoever had it before). Been playing it since!
Busted Blast City Monitor One
After trying different things; none of which seemed to get me anywhere, I grabbed a used-but-working flyback from TeknoService. Resoldered it in and turned the machine on. No crackle! No arc in the yoke! The meter read a 20kV voltage coming off of the anode cap! Calibrated HV and was greeted with a beautiful Naomi logo, already colour balanced.
Turned it off, grabbed my phone, and turned it back on.... no video and the board was tripping XRay protect. Sigh, at least I knew it wasn't the tube. Put work on that CRT off for now. I'll document all the different resistors and dioes and replace the ones that are rusted. Any ideas why the board is killing transformers (or causing a OV mode) would be helpful.
Blast City Monitor Two - Fixed Up!
The second monitor had an issue with a lack of blue and some a bit of a washout effect. Took the CRT out and pulled the board (I have become pretty good at it). Thought it could be a busted transistor and bought a pack (really cheap). Traced the B line through the transistors and to the socket.... noticing the pin was completely severed from the solder. Sucked up and resoldered all pins. Luckily the board was already recapped so I threw it all back in and had a marvelous blue!
The "washout" effect seems to only happen when the brightness is cranked up (anyone know what causes it? does it need focusing?) so after getting the colours calibrated I lowered the brightness. It still looks good! Convergence is a bit iffy on the right side, I'll get some strips to fix it later.
Threw it back into the second BC and hooked up my Naomi 2 + NetDimm. I have been playing a ton of MvC2, SF:A3, and CvS2001. Also Rhythem Tengoku with my gf.
