Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It sounds as if it has a heat-sensitive problem in its electronics. This would account for it working after being On (warmed up) for a period of time.
What problem does it currently have? I advise leaving it On, for at least 15 minutes, before trying anything further with it.
Let me know, please. I'd like to help with this problem.
I'm sorry to hear that.
I have been called to go offline suddenly, and will not be able to advise you further (for now at least), so therefore I have Opted Out, opening the case to other Experts in this category.)
My name is ***** ***** I will be your device technician for the day.
So as far what you are saying there are few things you can try.
