I had it from electro tania but there is not on this one the schematic for the power board GE3A for the model KDL-46EX521 only for the 32".
Thanks.

In general, unless you are comfortable with reverse engineering a specific circuit board, chances of finding schematic for power boards are next to impossible.
In consumer electronics, ever changing product cycles coupled with cheaper Chinese made parts has made TV servicing modular at best for some time. Not anything like what it used to be. Majority is basically computer generated modules and simply not feasible to repair.
Visuals, basics and datasheets/application notes are pretty the only thing left.
