Sony HDTV problem with ATSC tuner???

Archived from groups: alt.tv.tech.hdtv (More info?)

Last year we purchased a Sony KDP-65WS550 HD TV. No complaints. Has a
built in tuner. We did not subscribe to our local cable company for the
HDTV options. A month ago, I experimented with hooking up my old
antenna sitting in the attic to the ANT jack of the TV. Voila, I was
able to watch our local channels both digital and HDTV(?). Our local
PBS channel has a specific HDTV channel, and that was fantastic.
Now comes the bad part. One evening, Boom, (lightning strike, common in
Florida) and the picture from the ANT hookup is gone. After some
fiddling with the setup, I can again watch the digital local channels,
but the PBS HDTV channel is gone. With my limited knowledge, I suspect
the ATSC tuner is blown.
Can anyone confirm this and how would I test whether it is the tuner,
before I call the repairman.
Any suggestions will be much appreciated.

Are you watching the digital channels over the air because the HDTV and
regular digital channels would both use the same ATSC tuner if that is
the case. So if you get one type, chances are it is not blown.

The storm may have beat up your antenna or turned the antenna so it doesn't
get channels as well. I have trouble getting signals and channels appear
then disappear because of a poor signal.

If you can find someone with a ATSC set top box, borrow it to check your
antenna. I service DTV sets and I bought one for that reason.

In your case if you receive every other digital station the chances are that
the problem is the station or your antenna. If ALL the DTV channels are
very strong then you could have a case where the front end in your tuner is
damaged and only the weak channels can't be received.
