Thanks Steve
OK this is the procedure this morning. The BS9000 has been powered down & isolated since last night. The speakers have been in 'Audio' mode.
1) Unlplug the speakers from mains power
2) Move each speaker VIDEO / AUDIO / OFF switch to the OFF position
3) Connect each speaker to the BS9000 via PL Mk2 fully wired 8 core cables
4) Plug the speakers into the mains - note the standby lights now illuminated
5) Plug the BS9000 into the mains
6) Move the VIDEO / AUDIO / OFF speaker switches into the AUDIO position
7) Power the BS9000 up via the rear red push button. Note the speaker relays activating & the displays lighting up for a second whilst the standby lights extinguish - then the relays activating again & the displays shutting down - standby lights now illuminated. Note also a relay in the BS9000 activating - then de-activating - and the standby light now illuminated.
8) Attempt to switch to Option 1 using BL 1000 - point at BS9000 and press SOUND - 1 - STORE.
9) Nothing. No confirmation flash from the BS9000 standby light - no reaction to pressing CD or Radio on the BL 1000.
10) Try with Beo4 - press STANDBY & LIST simultaneously - Beo4 displays CONFIG? - press LIST until OPTION? is displayed - press GO - Beo4 displays V OPT - press LIST once - Beo4 displays A OPT - press 1 - Beo4 displays CD. No confirmation flash from the BS9000 standby light - no reaction to pressing CD or Radio on the Beo4 or BL1000
10) Press CD on the BS9000 keypad. Speaker relays immediately activate & displays light up - BS9000 activates & moves to the CD and starts playback. Displays both correctly display Volume / Track / Source data.
11) Wonders what could be at fault... 😕
