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
