AV1 is Composite Video and/or RGB capable.
AV2 is Composite Video or S-Video capable (ie. AV2S)
AV3 is Composite Video only.
As a test, take a look in the DVD's on-screen menus for something like,...
"Video Output Settings" ... if you find that RGB is selected, try switching to "Composite Video" instead, which should definately work on AV1, AV2 or AV3.
Otherwise, if possible try a better quality scart lead in case the pins are not making contact.
If internal AV switching is faulty, it's not something you will be able to repair yourself. You should call a service engineer.
