Sony 35" TV "tuner" bad? - coax not working, but RCA jacks are working

    My Sony 35" Trinitron TV (KV-35s40) was ON when lightning struck close by.
    I immediately lost picture and just had snow on the screen. I confirmed
    cable/satellite was ok by plugging the cable into a small tv for testing

    I can watch Satellite if I use the Svideo cable and the RCA plugs for audio.
    I cannot get any picture to come in when I try to use the coax cable into
    the tuner on the back of the TV.

    Is it safe to say the tuner is bad and I can just replace it? It seems like
    an easy enough job to remove it and solder a new one. Is there any other
    type of "test" I can do to confirm the problem is just with the tuner? Or
    did I already do enough by bypassing it and using the RCA plugs?

    Any recommendations on a vendor for this type of part? I know I can just
    Google the part number. I did find it easily.

    Replacing the tuner would probably fix it, might be worth checking inside
    the tuner to see if it's something simple, occasionally lightning does weird
    things like blow out a thin trace and not touch other parts.
