Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
ok here we go,
W26NM60 (red) & W18NK802 (blue) are your power mosfets. Check them for shorts (under 30 ohms). I clipped a pic on your photo to help you. Check pins 1-2, 1-3, 2-3
IC902 on the back of the power supply is your Power Factor Controller (PFC). Assuming the dot on the chip is pin #1, check between pin 6 & 8.
Both above check with meter on the ohms setting (Ω). The 200 scale will work fine. Anything under 30 ohms will need to be removed from the board and checked again. If they are good the meter is going to display either 1 or OL because its going to be in the (k) or (m) range and thats well above 200.
I had a bad pfc controller that shorted out and took the fuse with it. Let us know the results.
Lobo, is your tv doing the same as m1dp? (blowing fuse)
