OK, OK... let's plug the lady
Graphics garbag on boot!
Well, let's to the basic controls : all the fuses are OK, check all the cables, boot with/without the test mode switch selected, hard reset switch pressed ... still the same graphic garbages on screen.
Mhhh, so the next step will be to control all the tension/voltage. The generic manual ?for some reason? doesn't include the schematic for the common 'power supply' 125V board.
Anyway, I know I have one or two of these somewhere in my attic.... probably not working but it worths a try...
Ok, got one, not exactly the same reference, but the components look similar. So I quickly put it in 'parallel' mode
The game boot... after few seconds, it resets, and then it boots again... but interval between the reset and the boot seems to grow...
...and it gives me enough time to play it
Ok, now let's compare the two boards.
On the left, the original one named A082-90412-D
000, on the right the one used for my test here, named A082-90412-C
What would be the difference between these two 'revisions' ?
I suspect the original one not to work because of acid damages, see
Now, the funny thing... see the board I've used for this test
What it the purpose of that missing component (present on the original one) ? It's funny because the game is 'almost' working without that one?
