Re: Samsung 32" ln32b360c5d

I am getting really frustrating helping people in this badcaps.net troubleshooting problems, tracing out the board and draw up the diagram from poor quality pictures and not much feedback just to have the thread stop half way through.
It may be time for me to move on to some other forum/site. I quit FIXYA a year ago to come here to this forum.

@Peale, this is not directed at you. I'm just addressing budm's comment.

This entirely off topic, but budm/tom66, please see this thread.

https://www.badcaps.net/forum/showthread.php?t=23218

I have adopted my own "idol" idea back in November 2012. Hence, if there is no effort on the OP in terms of

a) picture clarity/quality,
b) some form of grammar, punctuation, spelling, etc (at least 7th grade passable)
c) using the search engine for common and well documented problems

I have moved onto the next thread never to return.

I know you, tom66, and selldoor have participated 100+ posts in one thread where the OP is either too lazy or can't follow instructions and frustration follows on all parties involved. If your gut says the OP is unreliable or can't follow instructions, then move on.

I am getting really frustrating helping people in this badcaps.net troubleshooting problems,

It may be time for me to move on to some other forum/site. I quit FIXYA a year ago to come here to this forum.

PS. These types of problems are not exclusive to badcaps.net. I'm on the eevblog forum, like tom66, and I have answered questions and never see the OP come back to view them or give thanks.

As tom66 says, there are just some people in this world who don't "get it".

Personally, I would like to see all the regulars (unfortunately so few) stay and participate, but obviously if you are feeling burnt out and frustrated, I can understand that.

If it helps, point people to this post to get the basics (picture composition, clarity, problem statement, layout, etc). Start with

https://www.badcaps.net/forum/showpo...7&postcount=21

which leads to the following example

https://www.badcaps.net/forum/showpo...94&postcount=1

I also like selldoor's set of questions particulary the one with experience. If the person is a newbie in electronics, but can follow instructions, then I'm more likely to help. If the person is experienced, but can't follow instructions, then I have moved onto the next thread.

No dude, please stay!

Your efforts are indeed valued and appreciated.

I can understand ditching fixya... other than a vtech phone hack, they've become a useless waste of bandwidth. But here, we're more than that.

If you need to take a break from the forum, go ahead, but please don't ditch the forum entirely.

Re: Samsung 32" ln32b360c5d

got to say if it was not for the likes of budm tom66 retiredcaps selldoor and a good few others i would probably not even be trying to repair electronics i did not know much about circuits and testing methods etc but the above people have gone out of there way to explain it in easy terms for me to understand ie if they say test this item and i am not sure how to or what meter settings they want me to test items on i just ask them politely and they go out there way to help me to understand the test methods etc i may not post much on here (as still learning) but these threads/and this site have helped me repair a good few lcds now even the guides on testing voltage regulators have helped me to understand how they work and what they should output etc so got to say guys many thanks for the good work and your own time to help me and others out it is appreciated.

Re: Samsung 32" ln32b360c5d

Bud, it was never my intention to frustrate you like that. I appreciate all and any help that you've given me. I should be quoting people to whom I'm replying.

The "dead short" reference was in reply to this post: https://www.badcaps.net/forum/showpo...5&postcount=23 , but I bundled information about the inverter transformers in my post, as well.

I've done my very best to answer all of your questions to the best of my ability. If I've done so erroneously, it's because of inexperience, not because of a lack of respect.

I hope that this doesn't dissuade you from the help that you give on these forums. You are an invaluable resource.

Re: Samsung 32" ln32b360c5d

So what is happening? The lamps stay on or not?

Let me try again:

With CN802 disconnected, the lights come one for about a second, and then they shut off.

then check the BL_ON and ps_on pins

Is the BL_ON and the INVERTER_ON/OFF the same thing? (pin 12) It's reading 4.47 VDC, with the connector disconnected.

PS_ON is pin 1, correct? It's reading 2.16 VDC.

Re: Samsung 32" ln32b360c5d

as per post 74 which is the correct model we should be looking at

Mine is the BN44-00289A.

Re: Samsung 32" ln32b360c5d

looks like budm may be going of bn44-00289b? looking at the pdfs hes done for you thats maybe where the confusion is?

Re: Samsung 32" ln32b360c5d

And after wasting all that times the OP never give any more feedback after I traced out the connections on the board. Very frustrating. I just want to tell then just get the new board and forget about troubleshooting down to component level.

Sorry to go off subject with this thread, but I thought I'd chime in and also give my support to budm. His hands on experience has proven to be invaluable on this forum and no has doubt helped many members fix their monitors/TVs. I understand your frustrations and suggest the following:

1) I've taken this tip from retiredcaps and PlainBill: if members asking for help can't be bothered with providing some good focused photos and a good description of the problem/symptoms, then I move on to someone else. Don't be bashful about demanding good photos before you provide help.

2) If you see someone asking for a diagnosis/solution to their problem without having even taken off the rear cover....

3) People who think you have an infinite amount of time and will generate a few pages of posts, then vanish for 2-3 weeks, come back and think you're going to drop everthing to reread their thread from beginning to end and take up where they left off. This shows total dissrepect for YOUR time. Move on!

4) Members who don't know basic electronics or have any tools/test equiptment. Nothing wrong with helping these members, but it will be very time consuming and some will be quickly get overwhelmed and leave the thread hanging, adding to your frustration.

5) Using the search function on this forum can answer a lot of the questions for members. I use it all the time. Members can run the same tests others did and report their results. Saves you from having to "reinvent the wheel" each time. Also, pointing them to retiredcaps excellent guide for "2 seconds to black" saves a lot of time.


I'll sure others can add to this post, but you, retiredcaps, tom66 and others have spent a great deal of your personal time to help others and it would be a great loss to see you leave. Don't let the few members who don't know any better drive you off this forum.

Re: Samsung 32" ln32b360c5d

I also post the diagram and redlined the 289A as well on post76. SAMSUNG uses these built-in pull-up resistors in later model for easy verification of the power supply-inverter board function by just pulling the cable between the main and the power supply board.

[vinceroger69]

Re: Samsung 32" ln32b360c5d

sounds a good idea even more so when you dont have spare resistors to hand. and yes my mistake i was going of the pdf in post 74 not 76.

[budm]

Re: Samsung 32" ln32b360c5d

I just need to calm down. I just get real frustrated when I cannot help solve the problems.

Re: Samsung 32" ln32b360c5d

its hard full stop in my opinion when the sets not in front of you. i now understand how good close up pictures really help you diagnose the problems we have thats why i have just got a good camera with macro on just need to read up on electronics more.

Was my information, above, helpful? The voltages weren't 0, so it must have those pull-up resistors, correct?

I just need to calm down. I just get real frustrated when I cannot help solve the problems.

Believe it or not, I understand. Most of the monitors that I repair are like 30 years old (arcade monitors) and I try and help a lot on places like KLOV. Sometimes, it's like "oh, just give it to me!"

I'll never leave a thread hanging without good reason. I did yesterday because...well, I need to eat and sleep, sometime....

Re: Samsung 32" ln32b360c5d

So the backligts does not stay on when plug between the main and the power supply-inverter board is removed , then next step is to find out what is wrong with this power supply-inverter board.

[Peale]

Re: Samsung 32" ln32b360c5d

At least we've narrowed it down to one of the two boards.

Do you think that inverter transformer could be a possible culprit?

If I pull it, would that allow the rest of the board to operate normally, as a test?

[budm]

Re: Samsung 32" ln32b360c5d

Yes, The transformer readings you had earlier, two are more than 3% off.
All the transformers and all the lamps have to be good, if the circuits detect any faults (lamp fired up but does not stay conduct, lamp draw too much current,etc.) in the first 3 seconds, the inverter will shutdown
