Panasonic TV - Does Not Connect to TV Signal (University Area RG6)

Panasonic 40" LCD TV.
Model no. TX-42A400B.

Would anyone like this old TV? We can't get it to connect to the TV signal via the aerial socket and it keeps saying 'no signal' on the screen, but maybe it could be used to play DVDs or something?
It has other inputs, so could possibly be used for gaming, DVD, satellite, cable, etc?
We honestly don't know what it can do, but maybe someone who has more knowledge than us can do something with it!
It has no remote control (just basic buttons down one side).
