Sony KDL-40BX420--2011 burning ribbon cable

[Harry Demers]

Seems like the 2011 version of the KDL-40BX420 has different PCBs.
The T-Con Board measures 1" by 21" & is located on the top edge of TV.
Other KDL-40BX420's (w/o the "2011" in the model number) have a
4" by 6" T-Con Board mounted at the 'top-rear'.
After replacing the P/S & Main boards from a SHARE (parts only) Sony
of the same vintage (w/ the same "2011" model number) my primary
TV started to burn the ribbon cable going from the Main to that 1" by 21"
T-Con board.

Does anyone have ideas as to where to go from here ???

Should always match part numbers on the boards down to the revision numbers, probably shorted mate.
