hi

i have tv fujicom pdp4230 with power supply usp440m 42lp, n3501q00156a
And the problem is that the mosfet w20nm60 and diode s20lc60us are burned
There is a component ucc3818n that is "bicmos power factor preregulator"

Someone knows what the solution why every time  these parts burned : W20nm60 and s20lc60us
strange, the tv works fine without this part :W20nm60 and s20lc60us

there is 2 parts of W20nm60

this tv work  between 100-240V

thanks
