I have the same problem. Went through all the steps and contacted CS. Right now it is a brick. Not sure how long to wait on this but patience is running low.
I too have the same problem.
It has been going fine but as of today it will not turn on.
It just shows a red light continually.
If I press and hold the on button in the front for 10 seconds the blue light will come on for 4-5 seconds and then it goes to red
The display does not work at all. I see nothing so I believe it is not even booting
I have looked at the forums but I do not see a easy answer.
I have not done any mods or tried any beta software.
I only use it for XBMC
I have upgraded this to version 18.104.22.168 on Friday night
It worked OK on Friday night and Saturday after the update
Today it has become a brick.
I too have contacted by email CS and will wait for a resolution
