After checking the datasheets of Thompson tuner, and I have one guess:

At board description, tda9887 is not there. This tuner needs to work
properly.

This small patch does enable it for your board.

You should notice that you may need to use some parameters for tda0887
to work properly, like using port1=0 port2=0 qss=0 as insmod options for
this module. (these are some on/off bits at the chip, to enable some
special functions - if 0/0/0 doesn't work you may need to test 0/0/1, ..
1/1/1).

Cheers,
Mauro.
