Hello. No knowing if it is possible to modify the internals another idea comes to mind.
If you do not have the BS4 connected via Masterlink to a Beovision TV this solution should be possible:
Connect a Beolink converter type 1611 with a Masterlink cable to the BS4. you can then connect a audio cable with 5 Pin din plug (audio signal conncted to pin 2, 3 and 5)in one end to the AAL connector on the 1611.
The BS4 should be put in option 2, so it can receive both audio and video commands.
With a Beo4 remote, press Standby button (the red dot) and List at the same time. Press list again until option is shown and press GO. press list until A.opt is shown. Press 2 and Go
You should then be able to activate the input on the 1611 converter with any video command (TV, V.MEM, DVD etc.)
