So I had Samsung come and replace the Y-Main board and perform a factory reset. Now my wallet is lighter the set works perfectly. No power on issues and no HDMI issues anymore.

I also have my old Y-Main board if anyone wants it. This is from a PS64F8500ARXZN.

Cheers
Where'd they get the board, even samsungparts.com (J&J) says they don't have it. :(

Well I live in Dubai, and I don't think they sold many of these TV's so there must be a fair stock of spare parts.


The technicians came with a new Power Board, Main Board, Y-Main and presumably have a stock of other parts as well. However these would be for the specific model number, and I'm not sure if it's interchangeable with other regions sets.


Before they came they asked for the TV serial number so they could bring the correct parts.

I have the exactly the same problem ,mine is still under warranty,they changed the main board, same problem .then they changed the power supply ,same problem,it seems that even Samsung tech don't know what is the problem.they are coming back today will tell you what happens


I have been looking to see if other owners of the Samsung PN64F8500AFXZA model have experienced issues with turning on their TV with the TV's original remote or universal remote. I have yet to find any threads talking about such problem. So here goes my issue:

Since I purchased this TV about a year and a half ago, it worked flawlessly with my universal remote MX-800 series. TV would turn off and on with no hesitation or delay. About a year into owning the TV, I started noticing that the TV would not respond to the universal remote. I figured maybe I was blocking the IR sensor, so I would stand directly in front of the TV for several seconds to ensure I was not directing the sensor elsewhere.

It turns out it just wouldn't turn on regardless of how direct I was with pointing the remote. It would occasionally happen here and there, and I would try again a few times and the TV would turn on. I didn't really think anything of it as it would always work quickly after. Over time, the TV started to respond less and less. I even tried turning on manually with the button on the TV and the original remote. Nothing would work. I began to suspect that it might be a capacitor issue that Samsung's have been plagued with as I had a similar issue with my older Samsung LCD. It seems there hasn't been anything reported on this particular model with this issue. Nowadays its hit or miss when I try to turn the TV on, sometimes it works the first time, other times it just doesn't work for a 30 min stretch, then I give up and come back a couple hours later to try again.

I have tried calling Samsung support, but they are the least helpful people on the planet. Not to mention my TV is now out of warranty so it would cost me money just to have someone come out and inspect it. I am hoping by posting this issue here, perhaps the true TV enthusiasts can offer some advice or should I just suck it up and pay for a Samsung tech to come out and look at the TV.

Appreciate any help!

I have several of the boards for the Samsung model PN64F8500AFXZA if anyone is interested. I have three X boards, two Y boards, three main boards, three power supplies and two sets of Y-board upper and lower buffer boards and two sets of X-board buffer boards.
I will sell cheap. Let me know if interested.
I have an opportunity to get this set for free with the exact same issue you had.
It is honestly too big for my house, but...
If the consensus is power supply, how much $
...and if that isn't it... how much for ...

Power supply is $75.00. I will sell any of my boards for $75.00
I paid $269.00 to Samsung for a new power supply. Turns out the problem with my tv wasn't in the four boards.
Let me know if you want a board.
Thanks

Would it be possible to list the part numbers of the boards you have? Also, do you have a price for the entire lot?


I have the same model TV, and I had a turn-on problem as well. Fortunately for me, it was the joystick power button in the back. However, I know the value of having extra boards around, so I would be interested in buying one or all boards in your inventory. I realize that some of the boards may be bad, and that is why I would be interested in buying the lot. Alas, that's the risk we take when new buy online.


BTW, how do you like the OLED? Did you get the LG 65" curved model?


Thanks,
Jim

I got my TV repaired via a Samsung Certified repair company (local to me). They sent the Y-board out for repair and also fixed some grounds they claim come loose. My wallet is $400 lighter but my TV works. So there is hope even if you can't get a new board.

Thanks for all the information. I also got a PN64F8500 that died before 18 months. A local repair shop here in San Diego confirmed the Y-board cant be ordered anymore so he offered looking at the board for repair. I gave him a heads-up of the HUGE possibility of more TV's coming to him with the same issues.

I have a slightly different model PS64F8500ARXZN but a similar issue. Problem started after 14 months so just outside of warranty.

For me it's a very specific problem though. If the TV has been on for a while then turned off, an immediate start will be fine. Similarly if you wait an hour or more it will start fine. However, if you try turning it on 5-10 minutes later it won't start. The screen stays black, and the red LED power light blinks slowly. You can then try to turn it on and off a few times it will start eventually.

After this 'non-start' the clock will always be reset to 01/01/2013.

Does your set of this as well?
I have very similar fault to you were the tv switches back on for the first 30-40 secs or so after going to standby but after that for ten minutes it wont start back up?
Have you managed to get it fixed and can you tell me the problem part?
Would help me get mine fixed as I have no warranty.
Cheers

It was fixed by replacing the Y-Board. The slow flashing LED on the front indicated a low power voltage on one of the boards apparently. The Y-Board in my case.

I had a factory reset done at the same time as well, but that was to resolve a HDMI issue which was unrelated, and resolved with the factory reset.

That is interesting, thanks for answering my question.
I would have sworn it would have been the power circuit board being a power issue.

At least I have an idea now what to do next.

Many thanks

Yeah, thats what i thought as well, but when the Samsung tech guy came, he measured the voltages coming out of the power board and they were fine.

Apparently they can't tell which board is at fault if the voltages from the power supply are ok, so they replace the main board, Y-Board and X-board in sequence until it was fixed!!

Had my power supply replaced earlier this year but the problem is back for me, undoubtedly the no longer available Y board.

So at this point should I let Samsung try to fix it and get the inevitable refund, or should I just live with it and hope it doesn't get worse?

My big fear is that the problem will get worse once out of warranty and I will be left with a dead large piece of glass.

Confirmed it is capacitor-related.

If your TV is ever in the mode and you need to watch it for whatever reason (TV accidentally got shut off at halftime or something), unplug it and press the power button joystick to drain the capacitors.

When you plug the TV back in, it should fire right up.

Meanwhile Geek Squad has ordered me new X and Y boards, so we'll see if they have a source for or stock of them other repair agents don't.

Ugh.

My packages from Best Buy/Samsung arrived today and I have a new main board and an X board waiting to be installed.

They had ordered a Y board, but they're… out of stock.

So basically the tech is required to install the main and X boards and see if the problem goes away, and if not, it's refund time.

In short, we're back to "if it's your Y board, you're screwed."

Pity as once again last night I marveled at how much I love this TV; stay tuned…

Update:
They came out and swapped out my X and main boards with no difference in the "no power on after a few minutes off" behavior (which we know is usually caused by the unavailable Y board.)

Bottom line is I'll be getting an exchange allowing me to trade in my 8500 towards a 65" OLED.

Pity, as I really do love this TV, but I'm not willing to take the chance that the issue progresses to the TV not turning on at all.

I bought an LG OLED TV to replace my Samsung plasma. I am more hopeful of the customer support from LG.

I have several of the boards for the Samsung model PN64F8500AFXZA if anyone is interested. I have three X boards, two Y boards, three main boards, three power supplies and two sets of Y-board upper and lower buffer boards and two sets of X-board buffer boards.

do you still have any y board or power supply board for PN64F8500AFXZA!?!

3 Capacitors Soldered on y-Board

I had the same issue with the power not turning on after the TV was powered off. I would have to wait 10 to 30 minutes before I was able to turn on the TV..
Samsung tech changed the mainboard 2X, power supply, wifi chip and bluettooth chip on 3 seperate visits.
On the 4th visit they changed 3 capicators on the Y-board (soldered on 3 capacitors) and the problem
was resolved.
It has been 8 days and the issue has been put to rest.
