Bring up this big picture and magnify it by clicking on it.
Look in the upper right area and you'll see a light green RF submodule
to the right of the Sky chip. Look closely at the green submodule. See
where it has turned brown in a brand new phone? Those chips get HOT!
Now look between the light green module and the chip below it marked:
338S0353. Why is the board BURNED out from under this IC? The blue is
burned off it, and those surface mounted components are scorched!
Something here ain't right!
Now, go down to 36MY1EE below it. Those components are burned, too!
The tiny IC or transistor upper right of 36MY1EE is Toasted, as is the
black component right above the red dot!
Outside the shield around 36MY1EE, to the right of it, notice more
components burned the board. The black square is probably a burned
transistor, too burned to read it.
To the left of 36MY1EE is 337S3754. Look above this IC...It scorched
the board, too! As heat rises, all this burning must have occurred when
this board was vertical in the same way the picture is...burned on the
UPside of these components....
SMP3i above 337S3754 is also burned on top....as are all the rest of the
chips, but to a much lesser degree....always on top in the picture.
Blue boards don't turn brown from soldering. They turn brown from
burning or intense overheating. Something in here got awful HOT!
It's NOT any kind of shadow because the three diplexers marked TQM on
the right show no heating or discoloration whatsoever. They are passive
RF components, not ICs under power.
Most disturbing.....this phone ran home on the plane I'm sure....while
they were all playing with the new toy. Taking off the RF shield didn't
scorch anything....the RF shielding is untouched.

If a man goes way out into the woods all alone and says something,
is it still wrong, even though no woman hears him?
