Hay guys, I'm in a grind with this LG microwave control board. It had a gentle but sevier death. Upon inspection found leaked capacitors, two damaged optocouplers , a blown inductor and a pitted IC- LNK 364DN. I changed the caps and inductor. I changed all the parts, although had to jerryrig the IC with a DIP package since the D-package is not available here in my country. After replacing the components I powered the bird up but to no avail. I saw that the new IC was getting quite hot and upon measuring the source to drain voltage of the IC it was at 300V DC. Kind of lost here. IMG_20210113_011148.jpgIMG_20210113_011005.jpg
