Easy Method to Repair a LG TV Using A Heat Gun

Most videos suggested remove-and-bake the main board to fix the LG TV cold soldering issue. I tried to locally heating the component without removing the main board from the TV. This is so much easier and better than unplugging and plugging 6-7 cables. Besides, a few of those connectors have very limited cycle time... I have seen a spec. on a similar connector rated for 20 cycles only.
If your problem is related to HDMI switching (can't detect devices being plugged into the HDMI ports), I suggest apply heat to the HDMI switcher chip first.
I feel lucky this time and I got that to work in my first trial.
I have seen different failure modes on the same TV but I was able to fix it by baking the main board.
Each 'bake' was able to keep the TV running for 1-3 months... I am actually getting tired of doing this. I stopped buying LG products 2-3 years ago....
