Dodgy RCA connectors need replacing

[vee dub]

Hi,
the RCA input ports on the back of my Sony stereo a faulty. The right
port seems fine but I get no audio out of the left when playing
through these connectors. I can get sound if I push the left RCA cable
around a bit. However as soon as I let go the sound disappears again.
It seems to be a connectivity issue. My question is, would resolving
this issue be best done by replacing the current RCA ports and
soldering in a new set. I am not experienced at electrical repairs but
thought if these where generic parts it would not be too difficult to
do the soldering if this was all that was required. Can anyone give me
any ideas if I am thinking along the correct lines?
Thanks

You should first try a dfferent set of RCA leads just in case they are the
problem, then try some contact cleaner just in case the fault is due to
corrosion of the contacts. If that fails, you should try and examine the
socket to see if it is a mechanical problem. Then pop the cover and see if
you can identify the problem from the other side - RCA sockets are very
simple - the fault in a socket should be obvious with a bit of poking. If
you can't get the existing socket to behave, then replacement is the obvious
option.

Could also be the connection to the PCB .. if its an older unit, the solder
joints might have broken away slightly from the PCB .. often a little bit of
heat from a soldering iron will reflow the joints and bring them back to
life .. worth a look before replacing it if it can help

**The most likely source of the problem is the connections to the PCB,
rather than the sockets themselves. As for parts, it depends on the type of
sockets used. You may need to use OEM parts.

No contradiction to any of the other posters, but a quick diagnostic test
would be simply swap the L & R connectors. Cheap leads are a likely cause of
failure. If the issue swaps over to the other channel then it's a lead
issue. Buy a new lead. Voila!
