Had a problem with my Sky+ box the other day, was seeing jerky on the screen so decided to do a full system reset. This can be accessed from the Sky Engineers Menu by the following
Press “SERVICES” on your Sky Plus Remote
Select Option 4
Next press 0, 1 and SELECT – you should now see the engineer’s menu.
Choose option 8, ‘Full System Reset’. The box will now take a few minutes to reset itself.
BE WARNED: This will clear your HD and thus wipe all your recorded programs!!
This solution has also been known to resolve pausing and recording issues. Enjoy!
