Thread: can't plug male coax cable into the Ant In of my new LCD

Just got a new Samsung LCD LN37A650.

I can see an Ant In at the back panel of the TV. It looks very much like a female, so I tried to plug a male coax into it. But it's so hard to put it in. I can only just hook it at the edge. Now I can see most of the channels including some HD channels, but some HD channels are showing blank and indicating weak signal.

Does anyone have similar issue?

One possibility - you cable has a heavier guage center wire which is too large for the jack. I've seen situations like this before. You might try a push on F connector, or a right angle F connector - anything that has a center pin that is small enough that it will fit your tv, but a female center opening large enough to accept your cable.
