Origin Electric PSE-324 Power Supply

[crtfool]

I am looking for a schematic diagram and a component parts list for this power supply. The board that I have has been very poorly repaired by it's previous owner, and it is a mess and still does not work properly.

Specifically, I need the original values for the following components:

SMD Resistors R352, R353, R354, R355 - currently installed resistors are 4.7 ohms each and are not SMD

SMD Resistors R356, R357, R358, R359 - currently installed resistors are 0.47 ohms each and are SMD marked R47

Transistors Q7 - 2SK2717 and Q6 - 2SK2127

This power supply comes out of a 32" Sony Plasma TV Model # KE-32TS2U

Thank you for any info that you can supply.

Ok Guys, I also now need the same info from above post. I was able to change out the 2 450 volt 230 mfd caps and now have sound, but now need to address the burnt out resistors and transister. This is a real common problem with the old Sony Bravias, but nobody wants to give up the ghost to fix them. Help please, I hate to let things like these get the best of me.

Ok, now I really need to get this going. I just fixed a 47" Vizio for the same customer and he gave me the Sony Plazma for free. I wish it was as east of a fix as the Vizio fuse number 3. Please help guys I would like to get this up and going soon.

Put in the model number. Set the drop downs to ALL and ALL.
There is a service manual PDF there.

Thanks for the site Toast, it is real good. I did download the PDF, and went to the charts on the bottom, and guess what none of these parts are listed. everthing is there exept the info on the power board. I think that Sony is just to worried about injury, and won't give out the info. I guess it is back to pounding the internet. somebody has to have posted a fix out there somewhere.

I hate when sony calls this a OEM part and you have to replace the hole thing. No Scematics for it just replace it.

Re: Origin Electric PSE-324 Power Supply

Ok here is what I do know. R352-R355 go from a Resistor with the marking of (224) and go to a Capacitor marked (2J224 L2N1) and R356-R359 go from a transistor marked (K2717 21) 900V 5A and go to the other leg of the same capacitor.

Re: Origin Electric PSE-324 Power Supply

Were you guys able to fix this power supply module? I have the same burnt out R47 resistors and presumably the related transistor too. Any guidance would be appreciated.
