Roland FP60x Dies for a moment

[venture]

I’ve experienced a problem with the FP60x, what I call Sudden Momentary Death. While playing the FP60x, for no apparent reason it suddenly loses power but only for a moment and then it’s restored, like a hiccup.

At first it occurred only about once ever couple weeks so I didn’t worry about it. However, over the last few weeks the frequency has increased noticeably, e.g. 3 to 5 times in one play session, but, it is not consistent. I can go days without experiencing it, and suddenly it comes back and disappears again.

I went to the store where I purchased the FP60x and tried out the same keyboard in the showroom. Surprisingly it also has the same issue. On two occasions I experienced it.

I’ve reported the issue to Roland and my vendor. I am told that they’ve tested the keyboard and could not find any issue. Nor has anyone ever reported a similar issue.

I cannot believe that i'm the only person who has experienced this problem on 2 FP60x's.

It has been suggested that perhaps it is my style of keyboard playing that is causing the problem. This idea is so laughable. My style of playing is with a soft hand and slow fingers. I think this method exposes the problem. If I were a hard and fast player i most likely would miss the hiccup.

. . . . . . perhaps it is my style of keyboard playing that is causing the problem. *****

Reading all of the situations . . . . . and MOST . . . . . importantly the fact that you were ALSO able to replicate this " hiccup" drop out audio effect on ANOTHER FP60x . . .lets work with those facts.
Tell me . . . . if there is a constantly displayed LED power indicator . . . . . . which, looks like to me, it might be having one located just above the extreme left . . . . . . power switch of the unit.

***** My best guesstimate, is that this is going to be a "left handed" related quirk.
When you are playing long duration heavy bass laden music, there is being a max demand on the units power supply.
Thus the units power supply is maxxed to its limit and shifts into current limiting for an instant . . . accounting for the temporary loss of audio.

WHAT TO DO ?
If I was correct, with there being a constant lit power LED . . . presenting a visual reference . . . . does it blink off during that audio hiccup?

Thaaaasssit . . . . . talk to me now . . . .

Wow! That was quick. I'm glad for your reply. Here are the facts.
Preface: I cannot reproduce this problem demand. Sometimes it happens once in a week, sometimes up to 5 times in one day.

1. FP60x is about 1 year old, or just under.
2. I have reproduced the Sudden Momentary Death issue on 2 FP60x, mine and the one in the Merriam Pianos showroom.
3. I have not noticed whether the LED lights blink or not. This is a good point and I'll keep my eyes open for it.

What i notice is that when it happens, there is a release of the piano action resistance, the tones drop. As soon as i release the key engaged at the time, all is normal again. If my finger were able to play fast, it might go unnoticed.

More Info:
It occurs when using my right hand. Sometimes, when trying to work out a melody i'm only using my right hand. I've been watching for specific key related issues, but it doesn't appear to be so. I've experienced in the C3, C4, C5 range. I am an armature player at best. My playing style is with a Soft hand and Slow fingers.
