As my previously reply suggests, I believe the problem to be at your end. But, it is entirely possible that I am wrong (it has been known), or that I misunderstand the problem.
With this in mind, if you are interested, please be so kind as to document in detail the sequence of events that show a problem, starting from power up, in the following way:
1) What do you do
2) What do you see
3) If what you see is no what you expected, what did you expect.?
Note also that you may need to re-initialize the unit – not doing so may be the cause of the problem.
