Hello,
I'm trying to remove the E1 board (y/c jungle)
from the main chassis of Sony kv-27xbr35.
It's a vertical board, soldered to connector,
and the connector soldered to the main A board.

Looking at the underside of the A board, I can see the
50 small pins of the connector.
What is the proper technique for unsoldering and removing
the connnector/board?

TIA
Dave
