I finally managed to get hold of an AV2 expander 8089111. Plugged in the adaptor and the scart leads and updated the connections menu,
No power light on the expander (adaptor is providing power), no light when selecting CAM Socket, TV accepts Expander option, but when I go back in the menu it is changed to DVD2.
Appears to be a DOA. Is there anything else to check or a common fault that is worth me getting checked / repaired?
Many thanks, Darreb
