Re: Phillips 42PFL5432D/37 Chirping and No Picture
No, I got them from Newark I believe. As long as the part number or specs are the same it should work.

Re: Phillips 42PFL5432D/37 Chirping and No Picture
The same diode circled in red on your picture, D912, was reading just like how you described on my board as well. I am pretty sure I replaced that one too. Since replacing everything you circled in both green and red, the television worked normally again.Leave a comment:

Yes I forgot to follow up, but this did fix the TV. Works well again
Thanks!

Re: Phillips 42PFL5432D/37 Chirping and No Picture
For the diode D912, after removing it from the circuit board, I tested it and it tested good. So I put that back in along with the D925. After installed again, the D925 tested good, but the D912 tested OL solid beep for both directions. What would cause it to read differently on the board compared to off? Is it because I don't have all diodes installed on the board? I currently have the two diodes that I know are bad, removed from the board because I'm waiting for those parts to come in.Leave a comment:

Thank you for the info and quick responses. I just added that last cap to my list of parts. I chose the longer life [URL="http://www.newark.com/jsp/search/productdetail.jsp?sku=04M9011"]Panasonic[/URL] capacitor for that one. I'll let you know how it is in a few days when those arrive and are installed.Re: Phillips 42PFL5432D/37 Chirping and No Picture

Re: Phillips 42PFL5432D/37 Chirping and No Picture
Thank you for the help. I've removed the suspected diodes and capacitors. The only two that read "bad" with the multimeter was ZD904 and ZD902. The others seemed to be good. I'm not sure about the capacitors. I'll post a picture below, they are bulging. Tested the caps with ohms, one read 11 M Ohms, The next one was 1 M Ohms, the last was dead completely. I guess I need three [URL="http://www.newark.com/jsp/search/productdetail.jsp?sku=74R3454"]capacitors[/URL] along with the two [URL="http://www.digike...Leave a comment:

Where can I get the diodes I need for this tv board? They are obviously blown...Leave a comment:

Re: Phillips 42PFL5432D/37 Chirping and No Picture
So you never replaced the bloated capacitors, only the two diodes? My photo is just like yours, they look "cooked" on the board, like a an arc burn or something. And also the readings show me on the multimeter that they are blown. Did you have any other blown diodes or bad caps? Also is there a way to test a capacitor with my multimeter?...Leave a comment:

Re: Phillips 42PFL5432D/37 Chirping and No Picture
I forgot to add, these readings were both directions, so I'm suggesting these are bad, right? They seem to be open, and not block directionally which a normal diode would read 0L one direction....Leave a comment:

Re: Phillips 42PFL5432D/37 Chirping and No Picture
I see you listed the 3 capacitors that needed replaced, with new model numbers and a link on newark.com to buy them. I need those, my question is, where did you get the diodes from? The ones that are bad, I have ZD904, ZD902, D925, and D912. My fuses are showing continuity so I guess those are fine. Also, was there anything else that needed replaced? The fourth capacitor, which is smaller, appears to be fine. I haven't tested my three large caps, but they are obviously bulging. C951, C952, and C953.Leave a comment:

Re: Phillips 42PFL5432D/37 Chirping and No Picture
Having the same problem, chirping, same model. I notice the three caps are bulged. Tested digital multimeter on the diodes. They all ring solid continuity, readings are:
ZD904: .025
ZD902: .021
D925: .046
D912: .000
Those readings are inside the circuit. I have not desoldered.
I believe if I replace the three caps (1500 uF 36V), it would bring the TV to life.
Also notice in the images below: The 3 bulged caps, and burn marks near ZD904 and ZD902.
What do you...Last edited by chief0x; 08-10-2012, 09:12 AM.Leave a comment:
