FP2 Screen stays randomly black with yellow LED


My FP2 is 7 months old and I already bought a new battery.

The screen stays randomly black when the phone is on and good battery level. And I have a yellow LED light.

Nothing happens when I push the power button, also for 10 sec. So, I have to open the phone, take the battery off and put it again in order to re-start the phone.

Somebody has a solution?

Thank you!
