Hi Michael,

Thanks. I've installed the latest firmware but this seems to have only made the problem worse. The screen now just flashes a blank screen every three seconds, the loading bar is not there (though some pixels are missing on the middle of the screen where it would be).

It's hard to say if this is a result of the firmware or just faulty hardware.

I will try some more testing.
