Default Help with stereo audio of Phono in Pioneer A80 amp

Hi, I'm new in this forum and not an expert in amplifiers.

I've got a Pioneer A-80 connected to a phono device. I have realised that the sound in one of my channels (the R one) stops after a while. In order to restore it, I have to slightly move the connector on the back of the amp, but after a couple of minutes it will stop working again.
The thing I can't understand is that when I put my amp in mono mode everything works fine, so it's only when I use it in stereo mode that this problem shows up.

Any suggestion?

You probable have a loose solderjoint in the amp somewhere.
Most certain on the input-board, around that R-connector.
