That you get noise seems to indicate a connection and an application, so some of what I write below may be irrelevant.
First of all, and most importantly, is it a PAL tuner (marked on its RF shield)? You'll get no joy out of NTSC or SECAM.
Do you have an alias to Apple Video Player in your Startup Items folder, or on your desktop if you do not wish for automatic loading of the player? With Video Player active you can configure its behaviour, choosing and excluding stations. What is the Mac's installed OS? Video Player might have been in Applications (Mac OS 9) or in Apple Extras originally, and has two help documents in its folder. It may be in OS 8.6 also, but, as I use 8.6 only on PowerBooks, I would have trashed it, and cannot now check.
Check also that the ribbon cable connecting the tuner to the MLB, which comes loose but taped down in the video tuner bay, is intact and correctly fastened at both ends.
