Help me understand this wiring of the headphone jack on an LG television

[curtisG58]

The headphone jack got ripped off the PCB of my LG TV. I've decided to not replace it. However since the jack got damaged, the TV thinks there's a headphone plugged in and mutes the internal speakers.

Looking at the schematic above of the headphone jack wiring, I should just be able to short out pins 3 & 4 (L and DETECT) to tell the TV there isn't a headphone plugged in as this appears to be a NC contact.

Am I reading this correctly?
Would appreciate any insights!
Thanks

All you need to do is to short HP_Detect to ground.
