See the silicone "blob" on the bottom of the power supply board ?
Remove it and clean the area with denatured alcohol then
re-solder the pins of the regulator IC.
HTH.

Re: Samsung PN60E6000GF 60" Smart TV turns off, red flashing power light

Now the TV is just trying to mess with me..

Last night I tried the blow dryer and heated the power board and main board separately; each for about 5 minutes. The TV did not turn off during this time. I then found out it had a default 15 minute timer to shut off if no input. I turned that off, and played a 90-minute video off a USB. The TV stayed on the whole video and stayed on the whole night (about 9 hours). From here, I figured it was fixed after the reset and was just being stupid about that 15min timer. I put it together and remounted it, for it to only turn off at random intervals again. Now it turns off after about 2-5 minutes, and I have tried to reset it again, without success.

One time it turned off after it was reset (during the setup process), but the sound was still present (just no picture). Not sure if this helps to determine which board it could be.

Also, it does not seem to decrease in duration now. It could stay on for 60s, and be turned off (after unplugging it) and then be on for 2 min.

Thanks and I appreciate the help so far.

cool,so main,logic board,sn,buffers and x main seem to work ok.
Back at the power supply. Or logic board but most likely power supply.
Saying that time it stays on decreases almost makes it sound like heat sensitive.
Have a can of air? If held up side down it sprays freon,thus freezing a target area. Got a hair dryer? I would heat up the powersupply in lets say a 1/4 area of the board and see if it shuts down sooner. Once area is found that seems heat sensitive,you can then use can of air upside down to freeze that area and pretty close target the component.
Try that also with the logic board,those BGA chips sometimes let go and then need a reflow.

Thanks for the quick and detailed response. I will give this a try tonight. Do I have to worry about any condensation from the compressed air?

--Update--

Resetting the TV got it to stay on longer. Each time I left it on, the duration that it stayed on, seemed to decrease. The TV is up to date on firmware, and obviously did not let me downgrade the version.

Just reattempted shorting the 3/4 pin (and found the thread for it). When doing that, with the cable removed connecting the logic board to the main board, it displayed a series of colors. Started white and then cycled to through blue, red, etc. Without doing anything, the TV did turn off during this process. I also reattempted it a few times, and the TV did the same thing (I believe how long it stayed on for, decreased each time too). Not sure if the pattern or order of colors matters.

Thanks

I found out the IR sensor was likely blocked when I had it on the floor.

The more I look into this problem, it appears to be a possible firmware issue. So I just reset the TV and have it on at the moment. Will wait to see what it does/doesn't do. Maybe update the firmware if problem persists and see if that fixes it.

Otherwise I will reattempt to get the test mode working if resetting doesn't work.

Now,on most samsungs what you do is disconnect the cable between the logic board and the mainboard,then make a short between 3&4 on the logic board,right top of board. Then plugin the tv,it should now display a variety of test displays.(on some you need to hit the power button).
Try that,with vs and va giving those voltages I'd say power supply is working yes.


Disclaimer: I don't know a whole lot about this model. Merely trying to help you to narrow down the problem board and some basic tests till somebody with more knowledge jumps in

Thanks for the reply. When disconnecting the main board and logic board, and shorting pins 3/4, nothing would display on the TV. When leaving the boards connected and shorting the pins, the tv came on as normal, but did not display any test displays.

Given when trying this, the TV is resting on the floor (no stand) and I am unable to press the power button. So I was trying to use the remote, could that be the reason for not getting the testing screens?

Behind the black plastic part for the stand is another board,the logic board,can we get a close up picture from that? Wanna see if we can get it to run the test patterns.

And maybe swap out that wired cap for the good of Alastairs blood pressure

Attached is the main board. And I will go ahead and order a replacement capacitor

--Bump--

I would be willing to donate some coin if someone can help. Just annoying having a 60" broken and using a 30" as a temp

i think you will find this is a Samsung Bluetooth Module

Re: Samsung PN60E6000GF 60" Smart TV turns off, red flashing power light

--VS--
Actual: 221.8
Rated: 219.0

--VA--
Actual: 55.1
Rated: 55.0

Since I believe these are within reason, and no signs of blown caps, should I assume the power board is fine?

Edit: I should also mention that since I owned the TV (for the 2 weeks it worked), it would intermittently go black and then go back to the picture and say "HDMI2" or etc. I didn't think much of it before, as I figured it was either my HTPC or the HDMI cord bottling the throughput, but now I realize that could mean T-sys board too?

Edit 2: I was checking the VSC and it was about 10v off. Then the TV turned off like it has been doing. I then retested the VS/VA and it was something like 70v/10v, respectfully.. Not sure what to make of this personally.

Why on Earth--is there a cap hanging off that board instead of being fitted correctly!
--recipe for disaster, that!

That is the capacitor I had suspected beforehand. The only replacement I could find was >x2 the Voltage and does not fit around the caps that were near it originally. So I ran a small bit of wire and used heat wrap to cover the leads of the cap to prevent arching or etc.

I will skim that thread a bit more in a little, but did not see anything to deal with my error code/problem.

Look on the power supply firstly you will have VS/VA test points measure them to see what you get they should match up with your panel sticker voltages

Let me go ahead and check.

Slightly off topic but would appreciate your answers.
What is the part which is in the red box.

Have you checked to see what supplies come up and if any do not?
