Default CD32 Port A fault

Hi,

I'm new to the forum... I come seeking help.

I've got an intermittent fault with my CD32, where it thinks I'm holding down the up arrow on the pad. It happens after a cold start or reboot but eventually goes away, at least for a bit.

I've checked the board for dry joints but I can't find anything obvious. I'm thinking a pullup resistor isn't connected somewhere and an input is floating, though I'm not very familiar with the circuitry.

The Joystick I'm using (a QuickShot) emulates Atari, Amstrad, MSX and Sega controllers. It happens on all settings.

Thanks.

I have the exact same problem with my second A600. I'm hoping once I get the capacitors replaced it might help fix a few problems.
