ND555 lights out

In the last few months, following power down my 555 has restarted thusly.

Note the lack of logo light (nor button lights, though I usually dim those). It’s accompanied by not responding to the remote or even appearing in the APP, though the wifi indicator is showing a strong signal. Power cycling it, sometimes several times has so far restored normal service so I’m reluctant to sent it off just yet with the fault intermittent.
Any others had similar?
Next time It’s off I’ll try exercising the Burndy connections in case they just need a clean.

Think that is just a start up light combination……mine does the same, but in play logo and buttons are lit……i have screen turned off.

I should add there’s no sound when it does that, that’s the clincher.
I just checked and putting it into standby with the APP leaves the logo lit, I have my buttons dimmed but now it’s not responding to the remote and dimming them vas the last thing I used it for.

Mine always responds to remote and app with sound……one to keep a watch on-or call dealer if still in warranty.
