...and back on this. That one is still waiting its turn in my 'half repair area"
It's time to plug that cabinet and see what's wrong, but first, a rapid visual inspection. First, the identity of that cow boy!
Inside...wow... the boards are really clean
The 'double board' game pcb :
The sound board :
The monitor on its back, behind the metal plate :
And finally the power supply :
Ok, let's plug the cow boy for the first time
As expected, not working!
At power on, there is the typical Nintendo sound/cry, almost the same than what you can hear when powering a DK or DK jr for example! Presuming the board is still alive somehow?
But not activity on the screen. Tried to credit the game, start a game... but there's absolutely no reaction on screen and not even a single sound?! As I said, the only sign of life is the 'screaming' sound at power on.
Next step, check all the voltage from the power supply, and check all the wirings...
There no test mode apparently?
