Re: Samsung PN60E530 no picture
I don't remember Ve. I never had a schematic for any of the boards on my 60E530. One voltage was supposed to be 211 volts DC; another, I think, was 5 volts.
Can you tell me on which board you probed a voltage of 113 volts?...

Re: Samsung PN60E530 no picture
In my case, on my Samsung 60E530, the problem turned out to be a bad Y-main ("Y-sustain" is a synonym) board. The voltage should have been 211 volts DC, but instead it quickly started about there (205) and quickly (60 seconds) it dropped to under 100 volts. (at that point I stopped measuring; it might have gone much lower if I'd continued.) Disconnecting the Y-main (only) allowed the voltage to continue at 211 volts, but of course the picture didn't display at that point.
The problem started out, in the summer of 2015...Leave a comment:

Re: Samsung PN60E530 no picture
Thanks; I just learned that. However, I can see from accessing my TV's service function that my version of firmware is 1018.1; supposedly the newest version of firmware should be 1012. something. This is a mystery that I cannot explain. Since things seem to be working okay, I'm not going to try to "update" that firmware....Leave a comment:

Re: Samsung PN60E530 no picture
My 60E530 failed due to a bad Y-main board.
How does somebody update the software for a 60E530? As far as I know, it doesn't have WiFi, nor a SD card, nor an Internet (ethernet) connection, etc....Leave a comment:

Re: Samsung PN60E530 no picture
Well, my 60E530 went through a time where that tactic was a consideration. But eventually it degraded so much that even this caution didn't work.
Here's how to determine if the Y-main board is bad: There are two voltage test points, maybe they were Vs and Va. The Vs is supposed to be about 211 volts: The actual value for the screen is on a sticker inside the TV, easily visible while you are servicing the TV. If Y-main board is bad, if you turn on the TV, the voltage quickly rises to nearly 211 volts, but then drops down to...Leave a comment:

Re: Samsung PN60E530 no picture
I'm not sure what you mean. When I was servicing my TV, it was standing upright, and I used a mirror to be able to easily see the image. I didn't hear any noise, but I wasn't listening for it. I should mention that I am nearly 58 years old, and it is well-known that high-frequency hearing gets reduced with age. If you are young, perhaps you are hearing noise causes by AC current flowing through those capacitors. I don't know what the current scan frequencies are, but it is certainly conceivable that you heard what for me was ultr...Leave a comment:

===============
Thanks for adding your comments.
My 60E530A3F gradually got worse and eventually the screen wouldn't light at all. I eventually solved the problem. I tried a number of things, described above in various messages. Eventually, I determined that the fault was in the Y-main board, and solved it by buying a new Y-main board from a Chinese place called "Buyqual", [url]http://www.buyqual.com/[/url] for a total of about $108 including shipping
Plugged it in a couple of weeks ago, everything...Leave a comment:

Re: Samsung PN60E530 no picture
I have a 60E530, which has failed, probably the Y-main (Y-sustain) board.
One chip which may go bad frequently is ICE3BR0665J. I've seen somebody offer a kit, consisting of this chip plus three tantalum capacitors, for about $20. That's WAY overpriced.
A better source should be DigiKey. [url]http://www.digikey.com/product-search/en?vendor=0&keywords=3BR0665[/url] For $1.84

I have a Samsung 60E530, bought early 2013. For 2 years it worked great. Middle of 2015, it began to exhibit turn-offs after the TV had been on for hours. But when I tried turning the TV on again, the sound came on, but the video did not. Initially, I had to wait about 5 minutes of "off"...Leave a comment:

Re: Samsung PN60E530 no picture
I received a new Y-buffer card yesterday. Unfortunately, after plugging it in, I see that it has not fixed things. If anything, things are WORSE: The video turns off all the time, now, as opposed to the original Y-buffer card. That latter behavior may be more consistent with the behavior seen by most owners of 60E530's than my original Y-buffer: My original buffer, installed, seems to have been associated with a thermal sensitivity that I previously described.
This may indicate that the actual problem is in the Y-main board.
Can anyone...Leave a comment:

Re: Samsung PN60E530 no picture
I believe that I have narrowed down the problem to the second-lowest chip on the upper Y-buffer board, or at least somewhere around it. I heat that chip with the hair dryer, and the TV video won't turn on. Once I let that chip cool down, the TV video turns on normally.
I have removed most of the silicone-rubber-looking material from around all the ICs on the Y-buffer boards, but not all of it. I have seen that there are some commercial silicone-rubber-removing chemicals available, but I don't know if they would be safe to use on a printed circuit...Leave a comment:

Re: Samsung PN60E530 no picture
My efforts last night suggest that heating the Y-buffer board exacerbates the problem. I suggest that other people try the same thing: Take the back off the TV, set it up on its base in some cool location (basement or unheated garage?) and see if the TV comes on. If it does, play a hair-dryer's output over various boards, and see if the thing fails. If it does, stop heating and let the thing cool down for a few minutes, then try again. Do this for all the boards in the TV, until you find the ones which are heat-sensitive.s

Re: Samsung PN60E530 no picture
I have just opened up my Samsung PN60E530 Plasma TV. No obvious visual defects (such as leaky or expanded electrolytic capacitor.) The thing fails to start at 69 degrees Fahrenheit, but should do so readily at 66 or so. I will take it down in the basement (where it is much cooler) and play a hair dryer over it to see what location of heating causes it to fail. Then, by blocking the heating using a large piece of cardboard, I should be able to narrow down the location of the heat-sensitive component, possibly to a single component.Leave a comment:
