Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
THANKS EVERYBODY!! got the parts in soldered them in an tv has been on for about two hours now. the only thing is the power mosfet that came in was smaller than the original so i had to bend the pins like a pitch fork. now i officially brought my first tv back from the dead. 32 inch proview might be next.
(parts, didn't know my links were broken)

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
the setting i use is the 2k setting it has the " -->l-- " symbol on it i posted a pic of it on post #14. i tested the bad mosfet under 2m, 200k, 20k and all pin combinatons tested .000. i tested good mosfet got no change or 1. on all pin combos. (under 2m, 200k, 20k) so now i searched for the replacement and found that it is an obsolete part ([url]http://search.digikey.com/scripts/DkSearch/dksus.dll?x=13&y=14&lang=en&site=us&KeyWords=W18NK80z[/url]). i got on help chat with them and they recomend...Leave a comment:

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
here are the results from mosfet circled in blue
positive on pin 1 to 2= .003
positive on pin 1 to 3= .003
positive on pin 2 to 1= .003
positive on pin 2 to 3= .000
positive on pin 3 to 1= .002
positive on pin 3 to 2= .000Leave a comment:

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
removed mosfet you circled in red test results
with positive on pin 1 to pin 2 =no change or 1.
positive on pin 1 to 3 =no change or 1.
positive on pin 2 to 1= no change or 1.
positive on pin2 to 3 = no change or 1.
positive on pin 3 to 1 = no change or 1.
positive on pin 3 to 2 = .514
all under 2k. i tried to use 200 setting but the number goes away too fast and is never the same
Now, the chip on the back. With positive on pin 8 to 6 is no change or 1.

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
the diode that was circled in green for me by retiredcaps is reading .454 and no reading the other way this means that the diode is still good and can be soldered right?
the bridge rectifier readings are
pin 1 and 2 .548 ,reverse is no reading
pin 2 and 3 no reading either way
pin 3 and 4 .566 ,reverse is no reading
so according to the video this should be good.
also @ mr.bill the chip#is sg6961sz b1aa1720713e

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
I now removed the bridge rectifier and like the mosfet am getting jumpy readings do thes indicate shorts?
i've tried every pin combination. some do stay at, 1. ,with no change and others jump high then back to 1. on the 200 ohms setting. the only results i am getting that stay steady on are when i change the meter to 2k voltage drop. anyway you can clear this up for me so i can get the proper results you need

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
i removed the power mosfet you circled in green and was getting jumpy readings with the 200 ohms setting. I noticed on the pcb in front of the chip is a voltage drop sign so i adjusted to the 2k ohms with voltage drop setting and got no change one way and a reading of .454 ohms the other....Leave a comment:

Re: Philips 42PFL5432D/37 I May Have Made my Problem Worse
the power mosfet you circled is 4 pins, the bridge rectifier is two pins.
will you please tell me what setting to use for ohms? i am only getting results from the continuty beep setting. also notice the smudge on the big brown lelon does it look bad to you and can that be the fuse popper?...Leave a comment:

Philips 42PFL5432D/37 I May Have Made my Problem Worse
Hello this is my first post on BadCaps but not my first visit. About 2 months ago i would go to power on my tv it would stay on for seconds then turn off, (red led turn to green back to flashing then solid red and was also squealing before this occurred) searched and found this site to help me with the bad caps on power board. The bad caps were 3 capXon 1500uF35v c951, c952, c953 and capXon 2200uF16v c955. I replaced them with the panasonic equals from thread "Philips LCD 42PFL5432D/37 - Bad PSU"
