While playing GTA V in morning silence I've said "enough" and got my GT30 naked to find the buzzing source. Surprisingly it wasn't located where everyone suggested (center board), but on the lower left corner of the TV (as google says "source of normal plasma buzz").
I wrote partial solution in the title, because I know what to do, to make it stop buzzing :
What I don't know is how to make it stop permanently. Any suggestions ?
edit: I've found some leftovers of liquid sillicone rubber and made a "piramide" of it, hoping it'll be pushed by the back cover of the TV :) I do not now what about the heat, but I'll worry about it later :)
