Relays on the power supply are clicking on and off numerous times, but it is hit or miss, meaning that it does not happen every time i plug the tv in. Also, there is no audio from the speakers, only from the headphone jack. Two capacitors have been replaced previously and none of the remaining caps appear to be bad. All fuses are good and there is proper voltage to the power supply. Checked voltage on all of the other panel connections(Vs, Vg, Va) and all appear to be as labeled. Just wondering where to go from here? Where to look next? Any assistance or nudge in any direction would be greatly appreciated.
If relays are clicking, the problem could also be the diode connected to the relay or its own power supply. Check whether the relay is getting power enough to remain activated. This chattering can also be caused due to relays becoming weak or by short circuits on its load.

I don't know about replacing a jack but BN94-01208C fits LNT1953HX is the main pcb that has all of the av inputs on it and it is a snap to change.
