Re: 47mf437B/37 replace the four caps and still have chirping and no power. which dio
Thanks budm. Those diode numbers P4KE250A & P6KE120A, do they replace what I think is a standard diode and a zenor diode? or am I looking at that wrong?Last edited by jdkruse; 12-26-2015, 09:20 PM.

thank you. I will pull and test them when I go back to work. have better equipment there. I'm getting parts from Mouser Electronics. any better recommendations?

those you mentioned have discoloring of the board under them as well as D924 & ZD906

Thank you. how will I determine what size diode to purchase? they are black with just a silver line (cathode) mark.Last edited by jdkruse; 12-26-2015, 07:57 PM.

I will pull them. Is the discoloring of the board an indicator?Last edited by jdkruse; 12-26-2015, 07:11 PM.

Re: 47mf437B/37 replace the four caps and still have chirping and no power. which dio
I have tested a few of them in circuit. I was wandering if there was a common diode or group to look at first. the board is slightly brown near some of the diodes does this indicate definitely a burned diode or do they get that hot? this is my first attempt on a television although I have replaced caps on a few boards in washing machines.
