Hi!
Just got my ACA500+ and installed it. Nothing shows up on the screen. The card blinks when powering up for a moment and thows no error code. I tried setting it to the unbrick mode to test booting from floppy. The card shows the 0_ with blinking underscore. But Ctrl+A+A does nothing (Doesn't boot from floppy)
I also tried cleaning the connection, but this had no effect. Removing the card and booting from floppy was working again.
Note: The screen is not the orginal one. It's a flat screen connected via a VGA adapter.
