Bush TV reverts to standby when scart connected

[Percy2011]

Not sure if this is the appropriate forum as it's my first post but just wanted to throw something out there. My 9yr old daughter has a Bush 22' LCD TV(22880F) with a dvd/vcr combi connected via scart (+ RF aerial for freeview).

We've just re-decorated her bedroom and when I re-connected the kit I discovered a weird problem. The TV seems to remember how it was last used(i.e. freeview input source or SCART input source). Now if I power the TV up after using scart source (whilst the Scart source is on standby)the TV goes into standby after approx 5 seconds. If I disconnect the scart from the TV it powers up correctly & I can re-connect the scart & use Combi or Freeview.

I swapped the scart lead for an identical looking (full 21 pin) scart lead & now seems ok! Anyone come across this before?
