Thought I'd share a happy ending. had a LG LED TV, you know the ones that the backlights last about 2 years @ 2014. Anyway This one had a shorted main processor LGE2132. Not a huge chip and relatively thin.
I'd got hold of a cheap board to swap in but found the IC for only $15 USD.
Sometimes you just have to have a go, about 20 bucks Aussie, nic e challenge.
anyway, Hot air station got the old one off clean, always a challenge without the best gear.
Chip arrived pre-balled, cleaned up the old site, used a sandwich press and cake stand as a pre-heat, good dose of flux, line d the chip up by eye best I could, hot air from above and flowed.
Cooled down , placement looked pretty close and miraculously booted up and all functions , display and inputs 100%.
Boards no longer available and $150 -200 used over here.
Feeling pretty damn good
