Ok, So I finally found some spare time during late evenings/nights and finally started to take a look at the monitor for my Taito Space Invaders.
Since I bought it a year ago I have never had any picture on it so I removed it from the cabinet in the warehouse and took it home to the bench.

The monitor is a Hitachi mcl-461f, a not to well documented monitor, It is actually a japanese TV that Taito used for some early games.

I realized I needed 100Vac to feed it, and thankfully I had a transformer from a Nintendo cabinet laying around that I could use.

First I hooked up a NES to the monitor and after som tuning I got a picture, but only if brightness and contrast was turned all the way up. I then hooked up my Space Invaders pcb (it did not come with the cabinet).
It worked but the picture slowly faded away until it was not visible at all. So when a unknown component got warm it did not work anymore was my guess.



I bought caps for the monitor a while back and decided to throw them in there, and I was more than happy when it actually seemed to have fixed the problem, now the brightness is very close to completely off and it still is bright and clear. Still have to leave it on a longer while for a stress-test.


So today I took the cabinet home from the warehouse to prepare it, it is a unknown PCB in it and the bezel that came with the cabinet is for Galaxy Wars, but I dont think the PCB is that game.
The wiring is messed up so I have to figure that out...



Stay tuned for update in the hopefully not to distant future

Thanks!
So i kept working on the game last night, tried to figure out what PCB they had in the cabinet when I got it.

This is how they had wired the Video signal, they tied RGB and Sync together to send it to the B&W monitor... there is a pot on each of the RGB-wires...


How do you quicktest this, I figured out the easiest way were to take my small PVM and BNC-alligatorclip wires  Smiley
Didnt know if this should work or not, I hooked them up at the potentiometers.


It worked straight away, dont know if the colors are correct, I supect not, but the PCB works and sound is working, I have not tried any inputs though..


So what game is it? It says Universal on the PCB:s so my guess would be Cosmic Monsters
https://www.arcade-museum.com/game_detail.php?game_id=7403

This is what the PCB looks like, It is now removed from the cabinet for good I think.


My next step is to clean the cabinet and then wire Space invaders in there instead.
I made a plan for it last night ....  lol

It is a mission impossible, but I have all the ones that I like. Cheesy
I don't have these:
Space Fortress, Laser Battle, Buck Rogers, Frogger, Astro Wars, Shooting Gallery, Money Money, Jack Rabbit, maybe some more.
My gameroom is full and I'm not planning to build a bigger one or remove games, so I'm happy with my collection, don't want more. Cheesy
