Following on from my SKY+ upgrade tinkering,??the box died last week, refuse to come out of stand by. DOH!, DOH!, DOH!, DOH!, DOH!
??Ebay to the rescue, got a replacement box in a few days, and put my disk in it, sorted
Or so??I thought
2 days Later it developeed the SAME fault, ODD my thinks
Tried the original hard hisk, NO joy,
So tried to power it up in a Air-conditioned room, still no joy,?? so not temperature related.
So get the USB serial Lead and see what is going on.
Unit seem to boot up OK, but wont come out of standby
Hmm, did some googleing and someone suggested a COLD boot with force firmware upgrade. Which seem to involve power cycling the unit with the “BACKUP” button pressed until the software update message is displayed and go and make get a coffee.
10 mins later, it rebooted it self, and has been working fine every since, VERY ODD
I did notice however that some of the numbers reported via RS232 port increased by 2,
A new version of firmware my thinks !!!

The register reported this a few days ago. By any chance did you upgrade the hdd?
