Sorry. Have you heard of lg xd brand bga chip before? I think it's coming out of the tv cards. I'm thinking 3 kilos. Is there gold in it?

Incinerate one ore two properly to grey-white ash, and inspect for bonding wires inside with magnifying glass or microscope. It could be done very quick

What I'm wondering is, do you have any ideas about the lg xd branded bga chip? Is there gold in it?

I'm not sure, couldn't find anything on internet. But there is a good chance there are gold bonding wires inside.
To know for sure: take Orvi's advice and test one.
Breaking one open and using a jewelers loupe could reveal the aluminum or gold bonding wires.
Learn to investigate and test what you have.

I had lg xd bga chips in operation, when disassembling I found that despite the appearance, like all bridges, the gold content was less. On some, the substrate was gilded, like everyone else's, on others it resembled a flip-chip design.
