Hi, i'm trying to repair my TV. The coax cable adaptor broke off, and
i'm trying to reattach it. I've tried soldering it, like i've soldered
many other things, but this does not seem strong enough to hold it in
place. Is there a better solder, or a better method of reattaching it?
It needs to be pretty strong because the tv coax cables are pretty thick
and not very flexible. Any suggestions would be appreciated!



Large surface areas are difficult to solder properly using garden-variety
radio/tv solder. Make sure you're using sufficient heat -- which would be
a gun type iron, 100-200W or higher depending on how much metal you're
trying to heat up. And don't skimp on the solder. If you're trying to
solder huge areas with small diameter solder, you'll have to feed the
solder very quickly. Also, try using flux on the area first, as no amount
of solder will stick well if the surface isn't clean.

As a last resort, you can try acid core solder. Never ever use this stuff
on circuit boards or part leads, but for large metal areas like shielding
cases and nuts/bolts, it's ok to try.

You might also consider using a quick-connect type connector on the cable.
This would prevent such major damage next time the cable was yanked on, as
it simply slips off with little force.

Forgot to mention an alternative if you just cannot get it soldered is to
use a panel mount connector (nuts on both front and back of connector).
You'll have to obviously open up the shield case (if there is one) to get
behind it, but if there's room in there, this is a good option.
