Need help with LG TV 42PM4700


Novice Member
I have a LG Plasma TV model 42PM4700 with a power supply problem.
I found a bad transistor (labeled Q501 ) mounted on a heat sink on the power supply board.
The part # is completely unreadable on it.
I can not find any info on the internet.
Would anyone have the info on that transistor ?
It is a TO-220 package

There's some info on it here in Italian.

Thank you for passing that on.
He gave the part # as TK13A25D which is a MOSFET.
So it may not be bad since i was testing it as a transistor
