Oh and the building up of a smps is actually a good idea, ill try that too thanksLeave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
Thank you for the link resources. Like I said, I did read up on allot of things, mostly how to test components and check if they are faulty. Learning to read schematics and have a solid back bone of knowledge is good, I agree with that. But that takes time. You cannot say I do not know how lucky I am. I might be old as hell to. (i'm not, but we literally still used dial up a few years ago where I am from - and pay out our ass for underwhelming internet)
I will read through those. Even then I will still ask dumb questions, because...Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
Thank you for all your help and input. That being said
I have been replacing boards for 5 years and I am over it. I have researched how to test diodes, caps, resistors, transistors, etc. and have applied that knowledge to test things like resistors, with great success. But now I am stuck with something, that I don't quite understand, so I am asking for help.
Usually when you don't understand something, you ask. Knowing how to test the output voltage does not sound too complex to me. No...Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
[B]1[/B]: I cannot find a ground, outside of the 12 pin connector. Hmm, I think so, its giving a volt reading, doesnt that make it safe to say yes? (honest question)
[B]2[/B]: 'BxxV' Is that the type of boards Joshnz was speaking about? The type of TV / SMPS, that the PCB MAIN must be connected to get a accurate volt output reading? (This is a ''always on'' case, for the record)
[B]3[/B]: I can respect that

Re: UA55JU6600KXXA SMPS -> PCB Main
Thank you for the input.
I have some questions:
[B]#1[/B]. Is my numbering charts correct? Please check reference image labeled [I]" [B]Numbering system[/B] "[/I] and [I]" [B]3, 5, 7, 9, PCB[/B] "[/I]
[B]#2[/B]. Is it safe to probe the 4 middle lines, as indicated on reference image [I]" [B]3, 5, 7, 9, PCB[/B] "[/I]? and if it is indeed the correct method and or safe, where do I put the black probe? I see no earth on the chassis, everything is connected, check reference...Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
There is nothing to solve, I just wish to know how to test a SMPS output. (Samsung specifically)
Is there no one who can do this? Dem Koreans to weird for yous?Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
I keep the black rod on the side with the grey cable, which usually means #1
The red bar I am probing all of them one by one, none of them, on either side, gives me 12.8v :what:
Do you still want me to check which one I was checking? lol
EDIT the black is on the ground line yeaLast edited by Jewdo064; 09-16-2016, 07:06 AM.Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
I think I am doing something wrong.
I replaced the panel of a different TV, that is completely working now. (UA55JU6000KXXA)
It uses the exact same SMPS (part number BN44-00807B) and a13v is supposedly, supposed to be 12.8 volts.
So I measured the volts on the power cable to the PCB main, and it doesn't even read @ half those numbers?
[U]Am i even measuring the volts the correct way[/U] ? ([U]please see attached[/U] image - I was informed / instructed, how to measure the volts,...Leave a comment:

Re: UA55JU6600KXXA SMPS -> PCB Main
Thank you.
The voltage readings I get are all between 3 and 5 volts, and is supposedly, supposed to be, at 12.8v.
Which means the smps is faulty.
What is most likely to be the cause of a lack of power like that, a faulty transformer id imagine, am I correct?
[I]From what I googled yesterday, the transformer is not easy to replace, and or, not worth it. So I will just replace the board. I would like to test the transformer though, for learning purposes. [U]Does anyone have a nice...Leave a comment:

UA55JU6600KXXA SMPS -> PCB Main
Hi. I would like some help with some things, if anyone would be kind enough to assist me.
The SMPS board of the UA55JU6600KXXA, (part number BN44-00807B)
the cable that powers the main board of the TV. what are the volts supposed to be at? Where can I find this info?
I have no electrical experience or degree, please keep that in mind.
I was trying to figure this out, but I have a feeling I am way off with my theory:
CNM08 only shows one key, thats a13v. Im not sure what that means.
CM802 shows ''power output'' a13v... -
Re: New Members - please post your introductions here
Hi. My name is Jew. I am a online gamer and biker by hobby. I like woman and beer too.
I worked as a computer technician for a couple of years, and decided to get some papers.
Ironically enough, after I got my papers, I could not find a job for a while, and ended getting hired at a Samsung repair center, in the audio and video department. Well its been 5 years and im tired of replacing entire boards and thought id step up my game. So here I am. May patients be there for those who dare assist me.
