This video is a way to handle modules or pcb from AC LG JETCOOL brand which is where the ic regulator burned. We replaced it with a regulator transformer with a current output of 12volt 450ma with 4 cables 2 large cable 2 small cables its advantages: we do not have to bother looking for HIS IC REGULATOR. the drawbacks: none at all, the pcb module works well, but it's only a little difficult to put the transformer into the indoor box. that is it Hopefully this video or tutorial can be useful for all friends.
