try using another speaker for the center channel and the left speaker, also watch your ohm load, most of the want a 4 ohm load. try to narrow it down to see if it is the speaker or the amp.

try to spray contact cleaner into the speaker port itself.. Powered off of course.. let it dry and try again.. this will clean any connectivity issues due to bad contacts.. as far as replacing jacks.. try the suspected "bad" speaker and wiring in another port.. if it works then the speaker and wiring is good and you have to check actual jack in which you were asking and back to auto amplifier circuit or transistors.

check your sound settings from the control panel it must have been set to 2.1 configuration
2. check for loose cables as well

First off, you want to correctly isolate what or which channels are/is bad. Use one good known speaker. Connect that speaker, one channel at a time, and test that channel with a fixed volume level (don't adjust the volume when you check each channel). Isolate the low level channels and make note of it. Note: each channel has their own amplifier. Once you've isolated the bad channels, take it to a repair shop and tell them the bad channels. They will then locate the circuit and narrow down the search to fine the problem - it's usually a bad solder connection. If it blows fuses - more likely a shorted transistor. In your case it's a bad solder connection.
