Re: Samsung LJ92-01511A SMPS Component
Found an equivalent zener diode manufactured by ROHM. It's a different package, but identical specs.
The part number is: TFZGTR30B -

I'm really looking for a substitute, because I can't seem to source the RLZ30BLeave a comment:

Samsung LJ92-01511A SMPS Component
I have attached an image of the back of the power supply. I had a zener diode ZD8001, that was open in both directions.
From my understanding, the zener in question is of type: Rohm LL-34
If this is the case then the part number for the zener would be: RLZ30B
Is this correct? What can I use as a substitute?... -

Actually, that is close. I have the a different board, that I located a picture of via shopjimmy.com. Thanks for pointing me in the right direction.Leave a comment:

Does anyone have a picture of the back of the power supply board? -
Re: Philips 50PFP5332D/37
I ordered a mix of FR and FC series Panasonic caps, and did a full board recap. Plugged it in, and everything worked as expected. The plasma played video for about 10 minutes before I lost all power, including any standby voltages. I did get a faint smell of fried electronics, but was unable to pinpoint the location of the smell on the board.
I am getting voltage on the main filter caps after the bridge rectifiers, but from there I am clueless on the issue.
Any suggestions?Leave a comment:

Re: Philips 50PFP5332D/37
I ended up going with Mouser since that is usually who I go through. I was able to source all the caps as Panasonic's, except one of the bigger caps. Total bill came to $25.56 for a full electro recap. I did run into a question, but pushed through it, in hopes that I made the right decision. I purchased both HC and BR (i think) Panasonic series caps. I thought I read something about one of the Panasonic series not being worth anything, and well I couldn't pull up the article quick enough so I pushed the order through.
However, while un-soldering...Leave a comment:

Re: Philips 50PFP5332D/37
Any suggestions on a rebuild kit or would it just be better to order from mouser?
Is there any suggestions on parts I should check before order new parts?
SMPS number: LJ92-01511A
Thanks everyone!...Last edited by dlaroche; 03-02-2015, 01:19 PM.Leave a comment:

Re: Philips 50PFP5332D/37
I'm not sure if the cap is getting hot. I haven't touched it while it is live
I just assumed somebody before me pealed some of the plastic coating off to see if the cap was bulged or leaking....Leave a comment:

I have tried every video in source the tv has, and it still shuts off every time a video source is applied....Leave a comment:

Re: Philips 50PFP5332D/37
Unfortunately, with all the power supply screws in I got the same readings.Leave a comment:

Re: Philips 50PFP5332D/37
Yes, I did take some tests this way. I will reinstall all the screw on the power supply and retest to verify my numbers.Leave a comment:

Re: Philips 50PFP5332D/37
Va is non adjustable on this unit. I'm thinking power supply rebuild, and go from there.
How do I enable test patterns via SSB?

Re: Philips 50PFP5332D/37
The power supply will start blinking before the front panel will. Is this the sequence you are referring to?
I just jumped pins 3 and 4 again, and monitored the Va voltage from startup. When the Va voltage came up it fluctuated a bit, and dipped down to 52v, but came back up to around 55v. It is averaging 55v right now, but on some test patterns the Va will drop down to around 52v.
The panel sticker is calling for a Va of 63. This is a Samung panel, and supply.Last edited by dlaroche; 02-28-2015, 07:33 PM.Leave a comment:

Re: Philips 50PFP5332D/37
Now I'm really confused. Which one is more indicative of my problem then?Leave a comment:

Re: Philips 50PFP5332D/37
According to the service manual the 6 red blinks is 5v supply. While the front panel is blinking 6 the small card on the power supply is blinking 2 blinks. There is a small chart printed on the PCB and 2 means Va. I'm confused by this conflict also.
Looked at the schematics and the SSB does take a 5v supply.Last edited by dlaroche; 02-28-2015, 07:04 PM.Leave a comment:

Re: Philips 50PFP5332D/37
However, the set plays the test patterns fine. I thought this test ruled out the power supply? The tv will remain on when there is no video plugged into it. It will power off if you try to access the menu or plug video into it. It will play video for about 2 seconds before powering off.Leave a comment:
