Yamaha p515 headphone output panning problem

Hi all, my first post here.
Got a Yamaha p515 which I like very much, but have noticed a problem recently which is causing issues.
Briefly, when using either of the headphone sockets to listen through after turning the unit on, I notice that the sound often seems to pan from one ear to another when playing (often gradually, stays on one side, then moves back to 'central' position for a while, then pans one way again). After using it for a few minutes the problem seems to disappear, and factory resetting the unit also seems to work in getting rid of the problem - but then the next time I turn it on there is the same problem.
I have no idea what the issue could be (have tried with various headphones, with the same results, so it can't be them), can anyone help me resolve it? Would prefer not to take it in for a service if possible, costly and logistically tricky to do where I live.
Thanks,
Oli

I have no idea, would that cause the problem? Anyone else experienced this issue?

Maybe you have some FX active (Phaser? Autopan?).

Is the panning truely random or are bass notes on the left and treble notes at the right?

Binaural sampling is only on the CFX piano sound and not on the Bösendorfer. Or on any non-piano sounds.

Does this panning happen with all sounds?

If the piano is actually broken we cannot remotely fix it an you need to talk to Yamaha/the seller.

Faulty relay in my case. Happened in CLP-645 for another user. Search the forum.

Hi, thanks for the input. @pawelsz, yes, that is the same kind of problem I have been having. Current workaround is to turn the piano on for a few minutes before starting to play, but not really an option in the long run I guess. You don't mention it in the other thread, but what was the broken part that was changed? Please feel free to dm me if that is easier for you, and thanks for your help.

Probably the relay which disconnects headphones when turning instrument on/off. Its role is to have silent switch on/off even when wearing headphones (no 'pop' sound). Serviceman from Yamaha needs to replace the PCB with midi ports, line outs etc. Those relays (two for two channels) are on this PCB. They look like small black cubes on PCB. Obviously if your issue is exactly same as yours.

Please share your experience when you have it repaired. Your case may be different.
