so long story short switch lite previous water damage (possibly coke tizer) sticky horrible stuff .
kept shutting down the switch .open the unit cleaned it all up found the ribbon cable from left board to right corroded along with the connector on the Dboard cleaned all this up managed to get the unit working put it all back together after a good clean.
only to find the right joystick not moving left or up (small movement but not a great deal ) cleaned the joystick up same issue so removed and replaced for new exactly the same problem tried another joystick again same issue (ive calibrated in the menu and right down are fine just up and left have small movement . i cant see any other corrosion on the board or in any of the ribbons / connectors
can someone point me the right direction for a pinout / test points or where to try next ??

the left stick and all other buttons work fine
many thanks
