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.
