thanks pusb87, I have tried that to no avail, as the android splash is disappearing I can see the resolution changing to a very course display before the blank screen, all within a second. When i tried the HDMI cable disconnect I saw the resolution of the TV/Minix appear on the tv screen (720p 60Hz) for a second before the screen when blank again, no sign of any video from Minix during this process. Given that I cannot get the recovery screen to appear, the box seems to be unrepairable, any thoughts appreciated.
Have you actually tried connecting to a PC to see if you can flash the device?
The fact you can't get or possibly see the recovery menu doesn't necessarily mean you can't use the burning tool!
Additionally, when you do follow @Villa 's advice, flash using the method previously discussed in this post & you'll hopefully retain all existing settings & data too....
