Okay I have had my DSM-520 for about 18 months with no problems.
Today I was using the device.
I wanted to switch Servers from my Network Hard Drive back to the Desktop to try a video file.
So in setup I went to change the media server and sure enough brought up the list of devices.
My Sony Desktop was listed twice one as Desktop the other as Sony VAIO Desktop... which I'd never seen listed before...
So I choose that and it gives a message... as if it is starting to configure...
The next minute the DSM-520 resets and the startup screen appears with a Startup Wizard... and the DSM-520 crashes...
I try to exit, nothing, I try to re-start, nothing.
I switch the unit off and on... nothing.
I unplug the DSM-520 and plug in again... I can no longer see even the splash screen.
I have checked the connections and the cable, the HDMI cable etc... all the obvious stuff...
On the DSM-520 itself the only sign of life is the power button does light up (blue) when I switch on and goes off when I switch off.
Also - I even tried plugging in a USB device with the latest firmware update... and switched the unit on...
Whilst the blue power lamp worked and even the blue lamp next to the USB port worked...
Still Nothing.
I have unplugged the unit
Any suggestions?
