I've got this digibox which does not respond to the Sky remote but if
this remote is tested on another digibox then it works fine. But if i
press the front buttons on the DRX300 digibox then it seems to work
but with the remote nothing happens. Any help appreciated.

Thanks

First, if you haven't already, you need to do a full power-down reset.
Unplug from the wall for at least 10 minutes. If still no joy, follow this
with a forced software update. If still no joy, then it's time to get the
lid off, and dust off your 'scope to check what's coming off the remote
sensor. If you don't have a 'scope, then you won't get very far tracking
down the problem, if it is a 'real' fault.

Beware the mains voltages can be relatively exposed in such boxes , when the
cover is removed

Just a crystal (not magnetic) earpiece will probably tell if the remote
receiver is working.

connect one wire of the earpiece to the outer metal of a phono or coax
connector on the rear, the other then touch to each of the traces going to
the receiver block in turn.
Usually 3 traces,
a/ would stop the stray pickup noise on an open earpiece (ground)
b/ would just give a click on touching (supply V)
c/ would give a varying click noise on pressing buttons on the handset.
(signal line)

NB No stray wires that could bridge other traces, just neat single wire for
probing.

If more than 3 going to the receiver block then try each in turn , one
should be variable click, related to keypad presses.
