Did you run the test patterns via jumper on the control board ?

No I don't know how but if instruct is simple please explain.

This one is like a thorn..

we need pics of your control board to show how to do that.
on samsungs you jumper pins 3/4 on the 4 pin connector. On some, they are just 4 round traces on the board.
I believe you also have to disconnect the mainboard connector going to the control board. Speaking of connectors, you were sure they were all well seated properly. Could be an improper connection somewhere.

I am no expert but does your control board now flash at 1 sec with Y connected and is Vs stable? If so any thought on an eeprom reset.

OK I decided to re-visit this one since i have been paying attention and learning more. also it has been abandoned here and is in my way so I just want to make it a display sign for my store or pull the boards and get the monster out of here.

One board that wasn't mentioned is the XR. However I just got someone to help me get it up on my bench so i will start over with the tests.
I think now that i don't have the stress of the old owner calling 3 times a day I can work thru it a little better than before. did not know if i should have started a new post but some of this info is still relevant.

Service manual anyone??

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

have you run the test patterns yet?

have you tried running it with only the top or bottom buffer attached?

Sorry I got busy on some other must do work and did not get to do my thing on this one. I did check it and it is same as before... red standby, 5V stdby voltage is correct as well as the 3.3v ps_on. then when i turn it on, the red led on front goes out no light on from. boot musical tone plays after a few seconds screen looks dark but you can tell backlights are ready and working.. like a black screen between commercials or something. Audio is clear for program/ch.
I then shutdown and disconnected the Y board from the A main and from the power. Turned it on again. Hear boot sound. VA goes to 59v VS goes to 216v. It stays there for about a full min possibly more, then it cuts off back to standby mode. If I press the power it will do this same cycle. I took the cover off the control board so I can take a photo. Phone was dead.. LOL I will post a good photo of it and the jacks as soon as it works again.
After I get the photos up I will not be back in here until monday, and it is looking like a busy day so it may be later monday eve before I can get back on here (central time US). Thanks for all you guys help!
What most online data has said was wrong with this on has not proven out so far. It is a challenge to solve... I also cannot find the service manual for this particular model. When it is powered on (not standby) the control board has a steady 1 second blink of a green colored led. even when I disconnected the Y-board.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

let me just confirm a couple of things. with all boards hooked up, do you have vs and va present, and do you have panel prime? also, is the heartbeat led on the control board pulsing at around a beat per second?

if this is the case, do the pin jump over slot 3 and 4 of the control board and disconnect the lvds cable that goes to the main board, if all is good, you should see your test patterns. if this happens, then your main board has the issue.

Hey I was still here so I saw your post. OK I connected the Y-board back. All boards connected as normal. VA is holding 59v for 10 min now, VS holding 216 same it just stays the same. Control board constant 1 second interval green led.
I did notice something I have been missing or that seems unusual. It powers on as soon as plugged in and when I press the power button it will not turn off. The only thing that happens is the front led comes on with the button press and goes back off on release. The boards stay the same.. in the powered up state. The old people had ordered a main board from shop jimmy already and it is the same with either one in it. I'm burnt out tonight.
I did download those guides but they don't appear to be for plasma, the info is great though so thanks.
I will do the test pattern things next time I can get to it.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

i would normally confirm test patterns prior to ordering the main, but hopefully that is the only fault.

do the test pattern test sooner rather than later. at least you will have more insight with the result.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

Your issue is the three blue caps on the Y-sustain board. If disconnecting the ribbon on the Y-sustain board allows the VS voltage to stay at 210V, then that is your failure.
There are several boards available on ebay for about $100 right now and shopjimmy is also in stock. There are lots of repair services available for $49 as well on ebay. just type in the search LJ92-01859A and they will all come up. If you don't want to go that route, some of the ebay sellers even sell just the caps for cheap. Those are all you need to replace.

One way to confirm it is going to be by using freeze spray and just spraying them. It won't work 100% of the time, but most often it will allow the TV to temporarily turn on.

Thanks but this is a long thread and this TV has a long history. the owners finally abandoned it here in Feb. --- They were trying to do their own repair off the internet but were too afraid to touch the boards.. possibly got bit by a cap i suspect. ANYHOW they were just buying boards and replacing things based on youtube videos and other forums. The Y sustain is a shop jimmy, it has already been replaced. So have both y buffer boards AND the mainboard. For clairity's sake when the Y-sustain is disconnected, the tv tries to boot then shuts down to standby as it should. I wish it was as simple as 3 caps...
I personally think the test pattern test will reveal some truth. Not there today just on here to see whats up.
Thanks
NOBODY seems to be able to find a service manual/schematic for this model.

Hey guys ok i finally got a few mins of peace so i did the test of the control board. jumped 3 and 4 together and disconnected the main board.
There was absolutely no change and no test pattern. i double checked my jumper and verified continuity between pins 3 and 4 (on this one it is actually 4 holes numbered 1,2,3,4) but again no test pattern.
1. TV turns on instant it is plugged in. Power switch has no effect.
2. Control board led blinking in its happy little 1 second interval.
3. Screen is lit but as if black picture. you can tell the backlights are on it is blacked out.
4. Audio boot chime still played even when doing this jump test.

Time to see about a control board?? Would a component level repair be possible or is it a logic chip PGM corrupted situation?

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

This irritating piece of s**t TV. Never buy a damn samsung plasma... what a crap hole.

I went ahead and ordered a control board was 14.99 but then SJ hit me with the ridiculous shipping of $10 so there it is.
If this doesn't fix it guess what is going to happen to this piece of steaming crap?

Found a place selling the service manual (we guess) for 16.99 but hell the board was cheaper.. pre-shipping.

Anyway will let you know if it works about 4 to 5 days from now.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

test patterns would of been good.

i still would of liked to know if disconnecting one of the buffer boards would of brought up half a picture.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

i still would of liked to know if disconnecting one of the buffer boards would of brought up half a picture.

y-buffers? if so we did all that already.

Only boards that haven't been tested are now the bottom buffers they are behind the metal strip that holds the screen in place.
I don't know at this point. I hate working on anything that someone else has already screwed with. HOWEVER how good would it feel if we fixed this sucker!!! LOL
"It may be stubborn but I am more stubborn!" that is a quote from a youtube tech video guy - RetroGameModz when i heard him say that i subscribed to his channel.. LOL

Do you think controller board?
It is possible SJ sold them a bad board but i doubt it, it would be my first one. they test them out pretty good.
SJ boards that have been replaced in this one already... Y-buffers upper and lower, Y-sustain, and A-main, oh I forgot about the power supply the people who brought it did that one first.. all bought from SJ. They had spent over $180 on boards and instead of returning them, they just left the TV here out front. Even after I told them i was not charging them anything on my end. I did the A-main but when it made no change i promptly returned it.
It would be a real pisser if it was the screen or the TV had been dropped or something like that.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

i must of missed the bit where you said that you had done half buffer testing.

if all of your voltages are present, you have screen prime, and the control test patterns didnt work, i can only assume that it is the control board. if you had a damaged panel, i would not expect that it would prime at all.

Re: Samsung PN60E530A3F - Clear sound but no picture no blink cold or warm same

OK UPDATE... FIXED!

This one is a very good lesson in not assuming that because several of the same model TV's problem is solved by replacing 3 caps, it doesn't mean that is necessarily what is wrong with your TV. These people who left this TV here watched Youtube then bought a power supply from SJ. I think they did not discharge the caps because that was the last time they wanted to touch a board on the inside. Then They came to me and did not listen to my advise but told me in no uncertain terms they knew what was wrong (again based on internet searches and youtube) and they only wanted me to put the board in for my fee of "labor only"... being a small town i kept my cool and tried to be nice, as well as trying to actually help but then as soon as i installed the Y-board they had bought.. They took the TV back even though it didn't work. Now is when you guys had been trying to help me help them so i screwed up and mentioned that we needed to test the Y-buffers.... no TV but a week or so later here it comes with the shop jimmy buffers... still didn't fix it... fast forward to Feb. here it comes again and this time it just sat there for all these months.
If you read these posts you will notice people trying to tell us to do the upper lower buffer tests, and like attainteddragon said more than once to do the control board test for the test patterns. I believe way back someone else suggested that.
I did that, bought a $14 plus $10 shipping control board, and it is fixed.
1. Trust your common sense, it is not a mystery. If your meter gets the correct readings on a board, move to the next TEST.
2. If you are a DIY person that is great but do not take it to a professional service guy and then tell him what to do and how to fix it. He may just allow you to do that.
3. If you have trust issues with the service center/persons, go somewhere else.
4. If you purchase a board that does not work from SJ they will refund you and all it costs is the shipping. (DUH)
5. The guys who take time out of their lives to help all of us in here and one another, owe you nothing and are helping out of simple kindness and would appreciate being treated the same.
Pay attention to what the guys with experience are telling you. school cannot teach you that. Youtube video may be a setup. Life experience can be far more valuable than even a PHD if that experience saves your life. (School of hard knocks)
Lastly this is a prime example of any education costs you something... one way or another.

Sorry for the limited picture this freaken TV weighs a ton. I will do a full screen pic after i get the back on it.
