RX3 play/cue buttons intermediately work on one deck

Hey there

Been having issues with deck 1's play/cue buttons. It usually will never work the first time I load a track but then the cue button work after i keep pressing it for awhile but no play button. However if i press and hold the cue then press down the play it will eventually stop flashing and play but that only after holding it down for at least 5 seconds.

deck 2 has no issues. There was a earlier post of it possibly being a problem with the solder on the ribbon connector because it sometimes working and not working seems to me like a bad connection.

or maybe it's a setting I don't know about?

any help is much appriciated!

thanx
