Why does my Sony television model # kv21se42/20 shutdown after the antenna wire is connected? If the wire is not connected the set stays on. In what area of the set should I look for a problem? What parts are likely to need replacement?

not familiar with the model but, are you referring to rabbit ear antenna, or a cable from an outside antenna? Is this connection on the tv a 75 ohm, i.e. a screw on connector like for cable tv? If so, I'd say you need to replace your antenna cable. It's also possible that your connector on your tv is faulty. If it's a cable type connector, those are actually only connected inside the tv by 2 copper strands. If one gets broken, from perhaps connecting or disconnecting a cable, then it causes a short. If the connector on the back of the tv is loose and can wiggle a little bit, it's probably broken. If you're going to try a new cable from your antenna, just run a loose one up to the antenna, without routing it. This way, if it's not the cable, you haven't wasted too much time installing a new line. If it is the connector on the tv, then just don't use it. It's probably not worth getting repaired. Hope this helped.
