Re: magnavox 37mf337b/37 parts advice
Parts are on the way! Checked D912 out of PSU it came back faulty. I will be using UF4007 diode for that replacement.P6KE120ACT ZD will be used for ZD902 ,and the three caps will be replaced with Panasonic EEU-FR1V102. Killian6pk, great point! Its alot easier to look at a pic than have to remember everything. I will update with progress as soon as parts are installed. Thanks again! Much appreciated!

I will search for the chassis number, I am interested in that now. The diagram is great in showing how the diodes are used, very interesting stuff.

I will definitely take D912 out,confirm the body numbers and diode test . I really appreciate all the input, I could not have done it without BADCAPS!! Thanks for the schematics as well VERY HANDY thing to have.

ZD902 is p6ke120a/744, now that i do see it. I am guessing i should replace with a P6ke120a? Thanks.

PSU # is 715T2484-4, there is a barcode also on PSU with ADPF24220R1P/P5PB74752533 as I am not sure what those numbers stand for. The back of the tv its self has model# and serial #.

I will do that! When I do find the info. I will be sure to pass it on. I will keep this thread open and update my progress. I am pretty good with electronics, this is my first tv and is a good learning experience.

Re: magnavox 37mf337b/37 parts advice
I will retest out of board and report my results. I am needing a KE12 74 , which is ZD902. I was just making sure I do not replace a ZD w/a regular diode.. I am not sure if uf4007 would be good for both faulty diodes.
Thanks for the quick responses, this site is amazing!!

Re: magnavox 37mf337b/37 parts advice
Hello! Yes, from what i understand ZD is zener diode. So does anyone know which ZD I will need? I will be ordering the parts described as above, but would like to make sure that I have a regular diode and a zener diode.
Thanks again!!

magnavox 37mf337b/37 parts advice
Hi! I am a new member and love the site! Thanks for all of the information, very helpful!!
I have a MAGNAVOX Model:37mf337b/37 that currently has the squeak/squeal going on. The Stock CapXon Caps are currently present in the t.v. @ a rating of 1000uf 35v.The three caps will need replacing due to bulging, also I tested the Diodes and found that two need replaced:
ZD902 (KE12 74) tested at .017 and .017, D912 (RD) tested at .001 and .001 while installed to PSU.
What brand of caps should be used?
What are the correct diodes that I will need?...
