Panny SCHT500 - disable active scart?

[mooperman]

hi guys,

had this piece of kit for a while and wont have chance to upgrade it for a while but in the meantime i need to find a way to disable the active scart as when i use my harmony to turn everything on the active scart kicks in and changes it to the DVD channel which is irritating, is there a service menu within this thing, i have looked through the setup menu but there is no option in there to cancel the active scart??

Thanks in advance..
