Thanks a lot fzabkar anything helps...
I stressed all searches without a single match for W5222 (or W5 222 or permutations..)
There is ZERO support or references for such codes
The clue to replace came from other brazilian repair forum with a similar TCON.
It is indeed a MOSFET and possible replacements are: 25C41 or 25C222
also with zero datasheet or reference...
I manage to find some.. and repaired the board as possible..
So far it was saved from landfills and working fine...
all voltages are within expected values.. panel working as expected
The BIG caps are all 20uF the smaller 4u7F (for future ref)
As i could realize this particular TCON has this typical fault quite a lot.
and all similar models. (they have a lot)
OEM support is ZERO. And the most common procedure is
replace the board... (from them)
So ...expect a lot in landfills...

BTW.. if you know the OEM reference for the COILS (all coils) in this board...
please put some here... it seems that COILS are shit.. they crack with thermal stress and age..
very hard to find equals
