LCD screen dark not showing

[Mloan]

Since about 5 hours the Fitbit wrist band showing no screen although it registers all data and can be read on phone .. pressing push button failed to show screen status.. what possibly has gone wrong and what needs to be done..

@Mloan, which Fitbit tracker do you have?

[Mloan]

Inspire

Been using it 3+ months

For swimming too

Happened today first time .. no water involved for 48 hrs

Thanks for the reply, @Mloan.  I moved this thread to the Inspire Help Forum, since it is specific to this device.

About 12 hours into the dilemma with my Inspire I sat down to unpin the strap and brushed it clean from dust .. while i manhandled the device it suddenly came alight. 
So please note I m reporting  the outage is over at last .. one may wonder why it happened and could it reoccur.

Dear All

I suffered black screen on Inspire device about 11am.

after 8-9 hours, I took extreme measures and took off the strap by manipulating the pin connector and started using brush to clean off any dust rubbing vigorously ..

And voila within no time my screen lit up 

Now which hidden vibes got generated to light the LED display I do not know
